Installation and service of this water heater requires ability equivalent to that of a Qualified Agency (as defined by ANSI below) in the field involved. Installation skills such as plumbing, air supply, venting, gas supply and electrical supply are required in addition to electrical testing skills when performing service.
ANSI Z223.1 2006 Sec. 3.3.83: "Qualified Agency" - "Any individual, firm, corporation or company that either in person or through a representative is engaged in and is responsible for (a) the installation, testing or replacement of gas piping or (b) the connection, installation, testing, repair or servicing of appliances and equipment; that is experienced in such work; that is familiar with all precautions required; and that has complied with all the requirements of the authority having jurisdiction."
If you are not qualified (as defined by ANSI above) and licensed or certified as required by the authority having jurisdiction to perform a given task do not attempt to perform any of the procedures described in this manual. If you do not understand the instructions given in this manual do not attempt to perform any procedures outlined in this manual.
PREPARING FOR THE INSTALLATION
1. Read the "General Safety" section, page 4-5 of this manual first and then the entire manual carefully. If you don't follow

the safety rules, the water heater will not operate properly. It could cause DEATH, SERIOUS BODILY INJURY AND/ OR PROPERTY DAMAGE.
This manual contains instructions for the installation, operation, and maintenance of the gas-fired water heater. It also contains warnings throughout the manual that you must read and be aware of. All warnings and all instructions are essential to the proper operation of the water heater and your safety. Since we cannot put everything on the first few pages, READ THE ENTIRE MANUAL BEFORE ATTEMPTING TO INSTALL OR OPERATE THE WATER HEATER.
2. The installation must conform with these instructions and the local code authority having jurisdiction. In the absence of local codes, the installation must comply with the current editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or CAN/CSA-B149.1 the Natural Gas and Propane Installation Code. All documents are available from the Canadian Standards Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131. NFPA documents are also available from the National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269.

FEATURES AND COMPONENTS

THE HYDROCANNON (SELF-CLEANING SYSTEM)
These units include The Hydrocannon (Self-Cleaning System) installed in the front water inlet, See Figure 1. The Hydrocannon inlet tube can only be used in the front water inlet connection. Do not install the Hydrocannon inlet tube in either the top or back inlet water connection. The Hydrocannon must be oriented correctly for proper function. There is a marked range on pipe nipple portion of the Hydrocannon, that must be aligned with top of inlet spud. A label above the jacket hole has an arrow that will point to marked portion of pipe nipple if the orientation is correct. If the arrow does not point within the marked range on pipe nipple, adjust the pipe nipple to correct. A pipe union is supplied with the Hydrocannon to reduce probability of misaligning the Hydrocannon accidentally while tightening the connection to inlet water supply line. Improper orientation of the Hydrocannon can cause poor performance of heater and can significantly reduce outlet water temperatures during heavy draws.

creating a spark at the pilot assembly. See Figure 3. Pilot gas is ignited and burns during each running cycle. The main burner and pilot gases are cut off during the OFF cycle. Pilot gas ignition is proven by the pilot sensor. Main burner ignition will not occur if the pilot sensor does not first sense pilot ignition.

Note: The Hydrocannon may have 1, 3 or 7 cross tubes.
FIGURE 1.
HIGH LIMIT SWITCH
The digital thermostat (Figure 2) contains the high limit (energy cutout) switch. The high limit switch interrupts main burner gas flow should the water temperature reach 203°F (95°C).
In the event of high limit switch operation, the water heater cannot be restarted unless the water temperature is reduced to approximately 120°F (49°C). The high limit reset button on the front of the control then needs to be depressed.
Continued manual resetting of high limit control, preceded by higher than usual water temperature is evidence of high limit switch operation. The following is a possible reason for high limit switch operation:
· A malfunction in the thermostatic controls would allow the gas control valve to remain open causing water temperature to exceed the thermostat setting. The water temperature would continue to rise until high limit switch operation.
Contact your dealer or service agent if continued high limit switch operation occurs.

IGNITION MODULE
FIGURE 3.
AUTOMATIC FLUE DAMPER
All units are equipped with an automatic flue damper that reduces heat loss during the OFF cycles.
Each automatic flue damper drive assembly is equipped with a "Service Switch", as shown in Figure 4
The "Ser vice Switch" has 2 positions: AUTOMATIC OPERATION and HOLD OPEN DAMPER. For normal operation the switch should be in the AUTOMATIC OPERATION position.
If there is a problem with the damper the "Service Switch" can be placed in the HOLD OPEN DAMPER position. When the switch is placed in the HOLD OPEN DAMPER position the damper disc will rotate to the open position and the heater may be used until vent assembly is repaired or replaced. DO NOT turn the damper disc manually; damage will occur to the drive assembly if operated manually. Refer to TESTING DAMPER OPERATION section of this manual for additional information.

DIGITAL THERMOSTAT FIGURE 2.
ELECTRONIC IGNITION CONTROL
Each heater is equipped with a Honeywell ignition module. The solid state ignition control ignites the pilot burner gas by

FLUE DAMPER FIGURE 4.
UNCRATING
The heater is shipped with the flue damper already installed. The wiring conduit runs from the thermostat to the damper drive cover. Before turning unit on, check to make sure the wiring conduit is securely plugged into damper drive.

INSTALLATION CONSIDERATIONS

LOCATING THE WATER HEATER
CAUTION
Property Damage Hazard

Flammable items, pressurized containers or any other potential fire hazardous articles must never be placed on or adjacent to the heater. Open containers or flammable material should not be stored or used in the same room with the heater.
The heater must not be located in an area where it will be subject to freezing.

· All water heaters eventually leak. · Do not install without adequate drainage.

Locate it near a floor drain. The heater should be located in an area where leakage from heater or connections will not result in damage to adjacent area or to lower floors of the structure.

When installing the heater, consideration must be given to proper location. Location selected should be as close to the stack or chimney as practicable, with adequate air supply and as centralized with the piping system as possible.

When such locations cannot be avoided, a suitable metal drain pan should be installed under heater. Such pans should be fabricated with sides at least 2" deep, with length and width at least 2" greater than diameter of heater and must be piped to an adequate drain. Pan must not restrict combustion air flow.

Fire or Explosion Hazard
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
Avoid all ignition sources if you smell gas. Do not expose water heater controls to excessive gas pressure.
Use only the gas shown on the water heater rating label. Maintain required clearances to combustibles. Keep ignition sources away from faucets after extended periods of non-use.

CLEARANCES
These heaters are approved for installation on combustible flooring in an alcove when the minimum clearance from combustion or non-combustible construction are followed as indicated in Figure 6 and Table 4.
In all installations the minimum combustible clearances from draft hood surface or vent piping shall be 6" (152mm). Vent piping passing through a combustible wall or ceiling must be a continuous run (no joints) and retain 6" (152mm) clearance unless an approved reducing thimble is used.
A service clearance of 24" (610mm) should be maintained from serviceable parts, such as relief valves, baffles, thermostats, cleanout openings or drain valves.

Read instruction manual before installing, using or servicing water heater.
There is a risk in using fuel burning appliances such as gas water heaters in rooms, garages or other areas where gasoline, other flammable liquids or engine driven equipment or vehicles are stored, operated or repaired. Flammable vapors are heavy and travel along the floor and may be ignited by the heater's igniter or main burner flames causing fire or explosion. Some local codes permit operation of gas appliances in such areas if they are installed 18" or more above the floor. This may reduce the risk if location in such an area cannot be avoided.
Do not install this water heater directly on a carpeted floor. A fire hazard may result. Instead the water heater must be placed on a metal or wood panel extending beyond the full width and depth by at least 3 inches in any direction. If the heater is installed in a carpeted alcove, the entire floor shall be covered by the panel. Also, see the DRAINING requirements in MAINTENANCE Section.
The heater shall be located or protected so it is not subject to physical damage by a moving vehicle.

INSULATION BLANKET

FIGURE 6.
NSF LEG KIT
The NSF Leg Kit (part number 9003425205) is needed only for applications that must conform to NSF/ANSI Standard 5. Installation of the NSF leg kit will increase the height of the unit and all connection points by 3 inches. See Figure 7.
Follow these steps to install the Leg Kit: 1. Unit needs to be lifted in a way not to damage unit or laid on
it's side to access the bottom of the legs.
2. Slide leg extension under leg and the bolt up through the bottom hole located in the bottom of the leg.
3. Once in place, screw nut down and secure.
4. Front of leg should line up with front of leg extension as shown to make sure weight of unit is distributed through the leg extension.

Breathing Hazard - Carbon Monoxide Gas
Do not obstruct water heater air intake with insulating blanket.
Gas and carbon monoxide detectors are available.
Install water heater in accordance with the instruction manual.
Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.
Insulation blankets are available to the general public for external use on gas water heaters but are not necessary with these products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. The water heaters covered by this manual meet or exceed the Energy Policy Act standards with respect to insulation and standby heat loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater, you should follow these instructions. See the Features and Components section of this manual for identification of components mentioned below. Failure to follow these instructions can restrict the air flow required for proper combustion, potentially resulting in fire, asphyxiation, serious personal injury or death.
· DO NOT apply insulation to the top of the water heater, as this will interfere with safe operation of the draft hood.
· DO NOT cover the gas control valve, thermostat or the Temperature-Pressure Relief Valve.
· DO NOT allow insulation to come within 2" (5 cm) of the burners, to prevent blockage of combustion air flow to the burners.
· DO NOT allow insulation to come within 9 inches (23 cm) of floor, (within 2 inches (5 cm) of bottom cover) to prevent blockage of combustion air flow to the burners..
· DO NOT cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.
· DO obtain new warning and instruction labels from the manufacturer for placement on the blanket directly over the existing labels.
· DO inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air flow.
HARD WATER
Where hard water conditions exist, water softening or the threshold type of water treatment is recommended. This will protect the dishwashers, coffee urns, water heaters, water piping and other equipment.
See the Maintenance Section in this manual for sediment and lime scale removal procedures.

CIRCULATION PUMPS

FIGURE 7.

A circulating pump is used when a system requires a circulating loop or there is a storage tank used in conjunction with the water heater. See Water Piping Diagrams in this manual for installation location of circulating pumps.
See the Circulation Pump Wiring Diagrams in this manual for electrical hookup information. Install in accordance with the current edition of the National Electrical Code, NFPA 70 or the Canadian Electrical Code, CSA C22.1.
All-bronze circulating pumps are recommended for used with commercial water heaters.
Some circulating pumps are manufactured with sealed bearings and do not require further lubrication. Some circulating pumps

FIGURE 9. HIGH ALTITUDE INSTALLATIONS

Fire and Explosion Hazard
Under no circumstances should the input exceed the rate shown on the water heater's rating label. Overfiring could result in fire or explosion. Gas and carbon monoxide detectors are available.

Installations above 2000 feet (610 meters) require replacement of burner orifices in accordance with current edition of the National Fuel Gas Code (ANSI Z223.1). For Canadian installations consult Canadian Installations Code CAN/CSA B149.1. Failure to replace orifices will result in improper and inefficient operation of the water heater resulting in the production of increased levels of carbon monoxide gas in excess of safe limits which could result in serious personal injury or death.
You should contact your gas supplier for any specific changes which may be required in your area.
As the elevation above sea level is increased, there is less oxygen per cubic foot of air. Therefore, the heater input rate should be reduced at high altitudes for satisfactory operation with the reduced oxygen supply. Failure to make this reduction would result in an over firing of the heater causing sooting, poor combustion and/or unsatisfactory heater performance.
Ratings specified by manufacturers for most appliances apply for elevations up to 2000 feet (610m). For elevations above 2000 feet (610), ratings must be reduced at the rate of 4% for each 1000 feet (305m) above sea level. For example, if a heater is rated at 78,000 Btuh (22.9 Kwh) at sea level, to rate the heater at 4000 feet (1219m), you subtract 4 (once for each thousand feet) x.04 (4% input reduction) x 78,000 (original rating) from the original rating.
Therefore, to calculate the input rating at 4,000 feet (1219m): 4 x .04 x 78,000 = 12,480 Btuh (3.7 Kwh), 78,000 (22.9 Kwh) 12,480 (3.7 Kwh) = 65,520 Btuh (19.2 Kwh). At 6000 feet (1829m) the correct input rating should be 59,280 Btuh (17.4 Kwh).

INSTALLATION REQUIREMENTS

GAS SUPPLY SYSTEMS
Low pressure building gas supply systems are defined as those systems that cannot under any circumstances exceed 14" W.C. (1/2 PSI Gauge). These systems do not require pressure regulation. Measurements should be taken to insure that gas pressures are stable and fall within the requirements stated on the water heater rating plate. Readings should be taken with all gas burning equipment off (static pressure) and with all gas burning equipment running at maximum rate (dynamic pressure). The gas supply pressure must be stable within 1.5" W.C. from static to dynamic pressure to provide good performance. Pressure drops that exceed 1.5" W.C. may cause rough starting, noisy combustion or nuisance outages. Increases or spikes in static pressure during off cycles may cause failure to ignite or in severe cases damage to appliance gas valves. If your low pressure system does NOT meet these requirements, the installer is responsible for the corrections.
High Pressure building supply systems use pressures that exceed 14" W.C. (1/2 PSI Gauge). These systems must use field supplied regulators to lower the gas pressure to less than 14" W.C. (1/2 PSI Gauge). Water heaters require gas regulators that are properly sized for the water heater input and deliver the rating plate specified pressures. Gas supply systems where pressure exceeds 5 PSI often require multiple regulators to achieve desired pressures. Systems in excess of 5 PSI building pressure should be designed by gas delivery professionals for best performance. Water heaters connected to gas supply systems that exceed 14" W.C. (1/2 PSI Gauge) at any time must be equipped with a gas supply regulator.
All models require a minimum gas supply pressure of 4.5" W.C. for natural gas and 11.0" W.C. for propane gas. The minimum supply pressure is measured while gas is flowing (dynamic pressure). The supply pressure should never fall below 4.5" W.C. for natural gas and 11.0" W.C. for propane gas. The supply pressure should be measured with all gas fired appliances connected to the common main firing at full capacity. If the supply pressure drops more than 1.5" W.C. as gas begins to flow to the water heater then the supply gas system including the gas line and/or the gas regulator may be restricted or undersized. See Supply Gas Regulator section and Gas Piping section of this manual. The gas valve on all models has a maximum gas supply pressure limit of 14" W.C. The maximum supply pressure is measured while gas is not flowing (static pressure).
SUPPLY GAS REGULATOR
The maximum allowable gas supply pressure for this water heater is 14 inches W.C. (3.48 kPa). Install a positive lock-up gas pressure regulator in the gas supply line if inlet gas pressure can exceed 14 inches W.C. (3.48 kPa) at any time. Regulators must be sized/used according to manufacturer's specifications.
If a positive lock-up regulator is required follow these instructions:
1. Positive lock-up gas pressure regulators must be rated at or above the input Btu/hr rating of the water heater they supply.
2. Positive lock-up gas pressure regulator(s) should be installed no closer than 3 equivalent feet (1 meter) and no farther than 8 equivalent feet (2.4 meters) from water heater's inlet gas connection.
3. After installing the positive lock-up gas pressure regulator(s) an initial nominal supply pressure setting of 7.0" W.C. while the water heater is operating is recommended and will generally provide good water heater operation. Some addition adjustment maybe required later to maintain a steady gas supply pressure.

4. When installing multiple water heaters in the same gas supply system it is recommended that individual positive lock-up gas pressure regulators be installed at each unit.
POWER SUPPLY
The water heaters covered in this manual require a 120 VAC, 1Ø (single phase), 60Hz, 15 amp power supply and must also be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/ NFPA 70 or the Canadian Electrical Code, CSA C22.1.
WATER TEMPERATURE CONTROL AND MIXING VALVES

Water temperature over 125°F (52°C) can cause severe burns instantly resulting in severe injury or death.
Children, the elderly and the physically or mentally disabled are at highest risk for scald injury.
Feel water before bathing or showering.
Temperature limiting devices such as mixing valves must be installed when required by codes and to ensure safe temperatures at fixtures.

Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and cause permanent injury upon contact. Short repeated heating cycles caused by small hot water uses can cause temperatures at the point of use to exceed the water heater's temperature setting by up to 20°F (11°C).

Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm and the physically/mentally disabled. Table 5 shows approximate time-to-burn relationship for normal adult skin. If anyone using hot water provided by the water heater being installed fits into one of these groups or if there is a local code or state law requiring a certain water temperature at the point of use, then special precautions must be taken.

In addition to using the lowest possible temperature setting that satisfies the demand of the application a Mixing Valve should be installed at the water heater (see Figure 10) or at the hot water taps to further reduce system water temperature.

Mixing valves are available at plumbing supply stores. Consult a Qualified Installer or Service Agency. Follow mixing valve manufacturer's instructions for installation of the valves.

DISHWASHING MACHINES
All dishwashing machines meeting the National Sanitation Foundation requirements are designed to operate with water flow pressures between 15 and 25 pounds per square inch (103 kPa and 173 kPa). Flow pressures above 25 pounds per square inch (173 kPa), or below 15 pounds per square inch (103 kPa), will result in improperly sanitized dishes. Where pressures are high, a water pressure reducing or flow regulating control valve should be used in the 180°F (82°C) line to the dishwashing machine and should be adjusted to deliver water pressure between these limits.
The National Sanitation Foundation also recommends circulation of 180°F (82°C) water. The circulation flow rate should be just enough to provide 180°F (82°C) water at the point of take-off to the dishwashing machine.
Adjust flow by throttling a full port ball valve installed in the circulating line on the outlet side of the pump. Never throttle flow on the suction side of a pump. See Water Piping Diagrams in this manual.
NOTE: These water heaters meet the NSF Standard 5 for sanitary installations when used with the leg kit part number 9003425205.
CLOSED WATER SYSTEMS
Water supply systems may, because of code requirements or such conditions as high line pressure, among others, have installed devices such as pressure reducing valves, check valves, and back flow preventers. Devices such as these cause the water system to be a closed system.
THERMAL EXPANSION
As water is heated, it expands (thermal expansion). In a closed system the volume of water will grow when it is heated. As the volume of water grows there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent Temperature-Pressure Relief Valve operation: water discharged from the valve due to excessive pressure build up. This condition is not covered under the limited warranty. The Temperature-Pressure Relief Valve is not intended for the constant relief of thermal expansion.

Explosion Hazard
Temperature-Pressure Relief Valve must comply with ANSI Z21.22CSA 4.4 and ASME code.
Properly sized temperaturepressure relief valve must be installed in opening provided.
Can result in overheating and excessive tank pressure.
Can cause serious injury or death.
This water heater is provided with a properly rated/sized and certified combination Temperature-Pressure Relief Valve (T&P valve) by the manufacturer. The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Pressure Relief Valves for Hot Water Supply Systems, ANSI Z21.22 · CSA 4.4, and the code requirements of ASME.
If replaced, the new T&P valve must meet the requirements of local codes, but not less than a combination TemperaturePressure Relief Valve rated/sized and certified as indicated in the above paragraph. The new valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater Btu/hr or kW input rate as shown on the water heater's model rating label.
NOTE: In addition to the factory installed Temperature-Pressure Relief Valve on the water heater, each remote storage tank that may be installed and piped to a water heating appliance must also have its own properly sized, rated and approved TemperaturePressure Relief Valve installed. Call the toll free technical support phone number listed on the back cover of this manual for technical assistance in sizing a Temperature-Pressure Relief Valve for remote storage tanks.
For safe operation of the water heater, the Temperature-Pressure Relief Valve must not be removed from its designated opening nor plugged. The Temperature-Pressure Relief Valve must be installed directly into the fitting of the water heater designed for the pressure relief valve . Install discharge piping so that any discharge will exit the pipe within 6 inches (15.2 cm) above an adequate floor drain, or external to the building. In cold climates it is recommended that it be terminated at an adequate drain inside the building. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve.

14

No valve or other obstruction is to be placed between the Temperature-Pressure Relief Valve and the tank. Do not connect discharge piping directly to the drain unless a 6" (15.2 cm) air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in adequate quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.
CAUTION
Water Damage Hazard
· Temperature-Pressure Relief Valve discharge
pipe must terminate at adequate drain.

CONTAMINATED AIR
Breathing Hazard - Carbon Monoxide Gas
Install water heater in accordance with the Instruction Manual and NFPA 54 or CAN/CSA-B149.1. To avoid injury, combustion and ventilation air must be taken from outdoors. Do not place chemical vapor emitting products near water heater. Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

T&P Valve Discharge Pipe Requirements:
· Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
· Shall not be plugged or blocked.
· Shall not be exposed to freezing temperatures.
· Shall be of material listed for hot water distribution.
· Shall be installed so as to allow complete drainage of both the Temperature-Pressure Relief Valve and the discharge pipe.
· Must terminate a maximum of six inches above a floor drain or external to the building. In cold climates, it is recommended that the discharge pipe be terminated at an adequate drain inside the building.
· Shall not have any valve or other obstruction between the pressure relief valve and the drain.

Corrosion of the flue ways and vent system may occur if air for combustion contains certain chemical vapors. Such corrosion may result in failure and risk of asphyxiation.
Combustion air that is contaminated can greatly diminish the life span of the water heater and water heater components such as hot surface igniters and burners. Propellants of aerosol sprays, beauty shop supplies, water softener chemicals and chemicals used in dry cleaning processes that are present in the combustion, ventilation or ambient air can cause such damage.
Do not store products of this sort near the water heater. Air which is brought in contact with the water heater should not contain any of these chemicals. If necessary, uncontaminated air should be obtained from remote or outdoor sources. The limited warranty is voided when failure of water heater is due to a corrosive atmosphere. (See limited warranty for complete terms and conditions).
AIR REQUIREMENTS

Burn hazard.

Hot water discharge.

Breathing Hazard - Carbon Monoxide Gas

Keep clear of TemperaturePressure Relief Valve discharge outlet.

Install water heater in accordance with the Instruction Manual and NFPA 54 or CAN/CSA-B149.1.
To avoid injury, combustion and ventilation air must be taken from outdoors.

The Temperature-Pressure Relief Valve must be manually operated at least twice a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the Temperature-Pressure Relief Valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot. If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions in this manual, and replace the TemperaturePressure Relief Valve with a properly rated/sized new one.
NOTE: The purpose of a Temperature-Pressure Relief Valve is to prevent excessive temperatures and pressures in the storage tank. The T&P valve is not intended for the constant relief of thermal expansion. A properly sized thermal expansion tank must be installed on all closed systems to control thermal expansion, see Closed Water Systems and Thermal Expansion on page 14.

Do not place chemical vapor emitting products near water heater.
Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.
For safe operation an adequate supply of fresh uncontaminated air for combustion and ventilation must be provided.
An insufficient supply of air can cause recirculation of combustion products resulting in contamination that may be hazardous to life. Such a condition often will result in a yellow, luminous burner flame, causing sooting of the combustion chamber, burners and flue tubes and creates a risk of asphyxiation.
Do not install the water heater in a confined space unless an adequate supply of air for combustion and ventilation is brought in to that space using the methods described in the Confined Space section that follows.

If you do not understand these instructions or have any questions regarding the Temperature-Pressure Relief Valve call the toll free number listed on the back cover of this manual for technical assistance.

Never obstruct the flow of ventilation air. If you have any doubts or questions at all, call your gas supplier. Failure to provide the proper amount of combustion air can result in a fire or explosion and cause property damage, serious bodily injury or death.

UNCONFINED SPACE
An Unconfined Space is one whose volume IS NOT LESS THAN 50 cubic feet per 1,000 Btu/hr (4.8 cubic meters per kW) of the total input rating of all appliances installed in the space. Rooms communicating directly with the space, in which the appliances are installed, through openings not furnished with doors, are considered a part of the unconfined space.
Makeup air requirements for the operation of exhaust fans, kitchen ventilation systems, clothes dryers and fireplaces shall also be considered in determining the adequacy of a space to provide combustion, ventilation and dilution air.
UNUSUALLY TIGHT CONSTRUCTION
In unconfined spaces in buildings, infiltration may be adequate to provide air for combustion, ventilation and dilution of flue gases. However, in buildings of unusually tight construction (for example, weather stripping, heavily insulated, caulked, vapor barrier, etc.) additional air must be provided using the methods described in the Confined Space section that follows.
CONFINED SPACE
A Confined Space is one whose volume is less than 50 cubic feet per 1,000 Btu/hr (4.8 cubic meters per kW) of the total input rating of all appliances installed in the space.
Openings must be installed to provide fresh air for combustion, ventilation and dilution in confined spaces. The required size for the openings is dependent on the method used to provide fresh air to the confined space and the total Btu/hr input rating of all appliances installed in the space.

DIRECT VENT APPLIANCES
Appliances installed in a Direct Vent configuration that derive all air for combustion from the outdoor atmosphere through sealed intake air piping are not factored in the total appliance input Btu/ hr calculations used to determine the size of openings providing fresh air into confined spaces.
EXHAUST FANS
Where exhaust fans are installed, additional air shall be provided to replace the exhausted air. When an exhaust fan is installed in the same space with a water heater, sufficient openings to provide fresh air must be provided that accommodate the requirements for all appliances in the room and the exhaust fan. Undersized openings will cause air to be drawn into the room through the water heater's vent system causing poor combustion. Sooting, serious damage to the water heater and the risk of fire or explosion may result. It can also create a risk of asphyxiation.
LOUVERS AND GRILLES
The free areas of the fresh air openings in the instructions that follow do not take in to account the presence of louvers, grilles or screens in the openings.
The required size of openings for combustion, ventilation and dilution air shall be based on the "net free area" of each opening. Where the free area through a design of louver or grille or screen is known, it shall be used in calculating the size of opening required to provide the free area specified. Where the louver and grille design and free area are not known, it shall be assumed that wood louvers will have 25% free area and metal louvers and grilles will have 75% free area. Non motorized louvers and grilles shall be fixed in the open position.

VENTING INSTALLATION

VENTING
THE INSTRUCTIONS IN THIS SECTION ON VENTING MUST BE FOLLOWED TO AVOID CHOKED COMBUSTION OR RECIRCULATION OF FLUE GASES. SUCH CONDITIONS CAUSE SOOTING OR RISKS OF FIRE AND ASPHYXIATION.

GAS PIPING
Contact your local gas service company to ensure that adequate gas service is available and to review applicable installation codes for your area.
Size the main gas line in accordance with Table 7. The figures shown are for straight lengths of pipe at 0.5 in. W.C. pressure drop, which is considered normal for low pressure systems. Note: Fittings such as elbows, tees and line regulators will add to the pipe pressure drop. Also refer to the latest version of the National Fuel Gas Code.
Schedule 40 Steel or Wrought Iron Pipe is the preferred material for the gas line of this water heater. It is imperative to follow the sizing recommendations in the latest version of the National Fuel Gas Code if Corrugated Stainless Steel Tubing (CSST) is used as the gas line for this water heater.
The heater is not intended for operation at higher than 14.0" W.C.natural gas, (1/2 pound per square inch gage) supply gas pressure. Exposure to higher supply pressure may cause damage to the gas valve which could result in fire or explosion. If overpressure has occurred such as through improper testing of gas lines or emergency malfunction of the supply system, the gas valve must be checked for safe operation. Make sure that the outside vents on the supply regulators and the safety vent valves are protected against blockage. These are parts of the gas supply system, not the heater. Vent blockage may occur during ice storms.

Be sure the gas meter has sufficient capacity to supply the full rated gas input of the water heater as well as the requirements of all other gas fired equipment supplied by the meter. If gas meter is too small, ask the gas company to install a larger meter having adequate capacity.

If copper supply lines are used they must be internally tinned and certified for gas service. Before attaching the gas line, be sure that all gas pipe is clean on the inside.

To trap any dirt or foreign material in the gas supply line, a sediment trap must be incorporated in the piping (see Figure 21). The sediment trap must be readily accessible and not subject to freezing conditions. Install in accordance with recommendations of serving gas suppliers. Refer to the latest version of the National Fuel Gas Code.

To prevent damage, care must be taken not to apply too much torque when attaching gas supply pipe to gas valve inlet.

Apply joint compounds (pipe dope) sparingly and only to the male threads of pipe joints. Do not apply compounds to the first two threads. Use compounds resistant to the action of liquefied petroleum gases.

GAS METER SIZE ­ NATURAL GASES ONLY

Fire and Explosion Hazard
Use joint compound or Teflon tape compatible with propane gas. Leak test before placing the water heater in operation. Disconnect gas piping and main gas shutoff valve before leak testing. Install sediment trap in accordance with NFPA 54.
Any time work is done on the gas supply system perform a leak test to avoid the possibility of fire or explosion.
1. For test pressures exceeding 1/2 psi (3.45 kPa) disconnect the water heater and its Main Gas Shutoff Valve from the gas supply piping system during testing, see Figure 21. The gas supply line must be capped when disconnected from the water heater.
2. For test pressures of 1/2 psi (3.45 kpa) or less, the water heater need not be disconnected, but must be isolated from the supply gas line by closing the Main Gas Shutoff Valve during testing.
3. Coat all supply gas line joints and connections upstream of the water heater with a non-corrosive soap and water solution to test for leaks. Bubbles indicate a gas leak. Do not use matches, candles, flame or other sources of ignition for this purpose.
4. Repair any leaks before placing the water heater in operation.
PURGING
Gas line purging is required with new piping or systems in which air has entered.
Purging should be performed per the current edition of NFPA 54 the National Fuel Gas Code.

OPERATION

Fire or Explosion Hazard
Gas line purging is required with new piping or systems in which air has entered.
To avoid risk of fire or explosion purge discharge must not enter into confined areas or spaces where ignition can occur.
The area must be well ventilated and all sources of ignition must be deactivated or removed.

Light the water heater in accordance with the Lighting and Operation Instruction label on the water heater and in this manual on pages 27 and 28.
The water heaters covered by this manual are equipped with an electronic control system that automatically sequences the Igniter, the 24 VAC Gas Valve, the Burner ignition, and flame sensing.
Before attempting start up, thoroughly study and know the exact Sequence Of Operation. See written Sequence Of Operation on page 25 and Sequence Of Operation Flow Chart on page 26.
Be certain that the water heater is full of water, that air is purged from the gas and water lines and that there are no leaks in the gas and water lines. Ensure all inlet water valves are open.

Read instruction manual before installing, using or servicing water heater.
PRIOR TO START UP
Installation and start up of this water heater requires abilities and skills equivalent to that of a licensed tradesman in the field involved, see Qualifications on page 6.
Do not place the water heater in operation if any part has been under water. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system and any gas control which has been under water.

FILLING THE WATER HEATER
Follow these steps to fill the water heater prior to start up. 1. Close the heater drain valve.
2. Open a nearby hot water faucet to permit air in system to escape.
3. Fully open the cold water inlet valve allowing the piping and water heater to fill with water.
4. Close hot water faucet opened in Step 2 as water starts to flow.
Read SEQUENCE OF OPERATION section of this manual prior to lighting and operating this water heater.
With above conditions satisfied, start the unit in accordance with the instructions on the operating label attached to the heater. For your convenience a copy of the instructions are shown on pages 27 and 28.

SEQUENCE OF OPERATION

The following information will describe the Sequence of Operation for this water heater.
1. Switch power on to unit.
2. Thermostat calls for heat.
3. Ignition Control performs diagnostic self check on system components.
4. The Ignition Control begins the trial for ignition.
5. The Ignition Control turns on the Spark Igniter and opens the Pilot Gas Valve.
6. The Ignition Control monitors the Flame Sensor during the ignition trial period.
7. If the Ignition Control does not sense the pilot flame during the ignition trial period, the Ignition Control shuts the Pilot Gas Valve and turns off the Spark Igniter. Depending on the water heater model, the Ignition Control will either retry the ignition trial at step 4 or lockout the ignition sequence. If the ignition sequence

is locked out, the power to the unit must be cycled to restart the Ignition Control.
8. If the pilot flame is proved during the ignition trial period, the Ignition Control turns off the Spark Ignitor and opens the Main Gas Valve.
9. The Ignition Control allows a 2 second pilot flame stabilization period to insure that the pilot flame is not extinguished by the main burner light-off process.
10. The Ignition Control monitors the Flame Sensor during the heating cycle. If the flame signal is lost, the Ignition Control shuts the Main Gas Valve and Pilot Gas Valve and re-starts the ignition process at step 4.
11. Once the unit is satisfied, the Ignition Control will shut off the Main Gas Valve and the Pilot Gas Valve and the unit will be in standby mode until another call for heat is initiated by the thermostat.
See the flow chart on page 26 for more information.

ADJUSTMENTS
ON INITIAL STARTUP SOME ADJUSTMENTS MAY BE NECESSARY.
Check Manifold and inlet gas pressures (see GAS SUPPLY SYSTEMS on page 13 and CHECKING THE INPUT on page 29-30.)
Check Pilot Burner (See Pilot Burner section on page 34.)
TESTING DAMPER OPERATION
With the Service Switch in the AUTOMATIC OPERATION position, check the operation of the flue damper three (3) times with the water operating controls for proper operating sequence:
· The damper disc must be open (in the vertical position) before the ignition and combustion process begins.
· The damper disc must be in the open position when the main burner is firing.
· The gas control valve must close and the main burner must have ceased firing before the damper disc begins its return to the closed (horizontal) position.
If during testing of the operation of the damper you find that there is a problem with the operation of the water heater when the Service Switch is in the AUTOMATIC OPERATION position: Reset the Service Switch to the HOLD OPEN DAMPER position and check operation again.
If the water heater does operate when placed in the HOLD OPEN DAMPER position:
· Refer to the EFFIKAL RVGP-FSF-SERIES TROUBLESHOOTING GUIDE on page 37.
If the water heater does not operate with the Service Switch in either position:
· Refer to the Troubleshooting Sections and Troubleshooting Checklist.

FAILURE TO CORRECT BACK DRAFTS MAY CAUSE AIR CONTAMINATION AND UNSAFE CONDITIONS.
· If the back draft cannot be corrected by the normal method or if a suitable draft cannot be obtained, a blower type flue gas exhauster must be employed to assure proper venting and correct combustion.
CHECKING THE INPUT
For installation locations with elevations above 2000 feet, refer to HIGH ALTITUDE INSTALLATIONS section of this manual for input reduction procedure.
1. Attach a pressure gauge or a manometer to the manifold pressure tap on the gas control valve and refer to Table 8, for correct manifold pressure.
2. Use this formula to "clock" the meter. Be sure that other gas consuming appliances are not operating during this interval.
(3600/T) x H = Btuh
T = Time in seconds to burn one cubic foot of gas.
H = Btu's per cubic foot of gas.
Btuh = Actual heater input.
Example:
T = 15.1 seconds
H = 1050 Btu
Btuh = ?

CHECKING VENTING

(3600/15.1) x 1050 = 250,000

The following steps shall be followed with each appliance connected to the venting system placed in operation, while any other appliances connected to the venting system are not in operation.
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1or the CAN/ CGA B149 Installation Codes and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
3. So far as is practical, close all building doors and windows and all doors between the space in which the water heater(s) connected to the venting system are located and other spaces of the building. Turn on all appliances not connected to the venting system. Turn on all exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Close fireplace dampers.
4. Follow the lighting instruction. Place the water heater being inspected in operation. Adjust thermostat so water heater shall operate continuously.
5. Test for draft hood spillage at the relief opening after 5 minutes of main burner operation.
6. After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous conditions of use.
7. If improper venting is observed during any of the above tests, the venting system must be corrected.

Should it be necessary to adjust the gas pressure to the burners to obtain the full input rate, the steps below should be followed:

3. Remove the regulator adjustment sealing cap and adjust the pressure by turning the adjusting screw with a screwdriver. See Figure 24.

Clockwise to increase gas pressure and input rate.

Counterclockwise to decrease gas pressure and input rate.

4. "Clock" the meter as in step 2 above.
5. Repeat steps 3 and 4 until the specified input rate is achieved.
6. Turn the gas control knob to PILOT. Remove the pressure gauge and replace the sealing cap and the Allen wrench set screw in the pressure tap opening.

FIGURE 24.
UNDER NO CIRCUMSTANCES SHOULD THE GAS INPUT EXCEED THE INPUT SHOWN ON THE HEATER MODEL AND RATING PLATE. OVERFIRING COULD RESULT IN DAMAGE OR SOOTING OF THE HEATER.

MAINTENANCE

VENTING SYSTEM
Examine the venting system every six months for obstructions and/or deterioration of the vent piping.
Remove all soot or other obstructions from chimney which will retard free draft.

REMOTE STORAGE TANK TEMPERATURE CONTROL

The water temperature in the remote storage tank (if used) is controlled by the storage tank temperature control. The sensing element is mounted in the hot water storage tank, see Water Piping Diagram section.
A change in water temperature in the storage tank lower than the tank temperature control setting will cause the sensor to activate the circulating pump. The pump then circulates the water through the heater where the thermostat senses the drop in water temperature and activates main burner operation of the water heater.
If the storage tank temperature control is out of calibration, replace with new control.
SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL TO SHUT OFF, TURN OFF THE MANUAL GAS CONTROL VALVE TO THE WATER HEATER.
TEMPERATURE-PRESSURE RELIEF VALVE TEST

FIGURE 25.
If the Temperature-Pressure Relief Valve on water heater weeps or discharges periodically, this may be due to thermal expansion.
NOTE: Excessive water pressure is the most common cause of Temperature-Pressure Relief Valve leakage. Excessive water system pressure is most often caused by "thermal expansion" in a "closed system." See Closed Water Systems and Thermal Expansion on page 14. The TemperaturePressure Relief Valve is not intended for the constant relief of thermal expansion.
Temperature-Pressure Relief Valve leakage due to pressure build up in a closed system that does not have a thermal expansion tank installed is not covered under the limited warranty. Thermal expansion tanks must be installed on all closed water systems.
DO NOT PLUG THE TEMPERATURE-PRESSURE RELIEF VALVE OPENING. THIS CAN CAUSE PROPERTY DAMAGE, SERIOUS INJURY OR DEATH.

Burn hazard.

Hot water discharge.

Explosion Hazard

Keep clear of TemperaturePressure Relief Valve discharge outlet.
It is recommended that the Temperature-Pressure Relief Valve should be checked to ensure that it is in operating condition every 6 months.
When checking the Temperature-Pressure Relief Valve operation, make sure that (1) no one is in front of or around the outlet of the Temperature-Pressure Relief Valve discharge line, and (2) that the water discharge will not cause any property damage, as the water may be extremely hot. Use care when operating valve as the valve may be hot.
To check the pressure relief valve , lift the lever at the end of the valve several times, see Figure 25. The valve should seat properly and operate freely.
If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater and drain the water heater, see Draining And Flushing on page 32. Replace the Temperature-Pressure Relief
Valve with a properly rated/sized new one, see TemperaturePressure Relief Valve on pages 12-13 for instructions on replacement.

Temperature-Pressure Relief Valve must comply with ANSI Z21.22CSA 4.4 and ASME code.
Properly sized temperaturepressure relief valve must be installed in opening provided.
Can result in overheating and excessive tank pressure.
Can cause serious injury or death.
ANODE ROD INSPECTION
CAUTION
Property Damage Hazard · Avoid water heater damage. · Inspection and replacement of anode rod required.
The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding tank,

31

water ions attack and eat away the anode rod. This does not affect water's taste or color. The rod must be maintained to keep tank in operating condition. Anode rod deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician, and at a minimum should be checked annually after the warranty period. Artificially softened water is exceedingly corrosive because the process substitutes sodium ions for magnesium and calcium ions. The use of a water softener may decrease the life of the water heater tank. The anode rod should be inspected after a maximum of three years and annually thereafter until the condition of the anode rod dictates its replacement. Anode replacement is not covered by warranty. NOTE: artificially softened water requires the anode rod to be inspected annually.
DRAINING AND FLUSHING
Burn harzard.
Hot water discharge.
Keep hands clear of drain valve discharge.
It is recommended that the water heater storage tank be drained and flushed every 6 months to reduce sediment buildup. The water heater should be drained if being shut down during freezing temperatures. See Features And Components in this manual for the location of the water heater components described below. TO DRAIN THE WATER HEATER STORAGE TANK: 1. Turn off the electrical supply to the water heater. 2. Turn off the gas supply at the Main Gas Shutoff Valve if the
water heater is going to be shut down for an extended period. 3. Ensure the cold water inlet valve is open. 4. Open a nearby hot water faucet and let the water run until
the water is no longer hot. 5. Close the cold water inlet valve to the water heater. 6. Connect a hose to the water heater drain valve and terminate
it to an adequate drain. 7. Open the water heater drain valve and allow all the water to
drain from the storage tank. 8. Close the water heater drain valve when all water in the
storage tank has drained. 9. Close the hot water faucet opened in Step 4. 10. If the water heater is going to be shut down for an extended
period, the drain valve should be left open.

5. Ensure the drain hose is secured before and during the entire flushing procedure. Flushing is performed with system water pressure applied to the water heater.
6. Open the water heater drain valve to flush the storage tank.
7. Flush the water heater storage tank to remove sediment and allow the water to flow until it runs clean.
8. Close the water heater drain valve when flushing is completed.
9. Remove the drain hose.
10. Fill the water heater - see Filling The Water Heater in this manual.
11. Turn on the electrical supply to place the water heater back in operation.
12. Allow the water heater to complete several heating cycles to ensure it is operating properly.
RECOMMENDED PROCEDURE FOR PERIODIC REMOVAL OF LIME DEPOSITS FROM TANK TYPE COMMERCIAL WATER HEATERS
The amount of calcium carbonate (lime) released from water is in direct proportion to water temperature and usage, see chart. The higher the water temperature or water usage, the more lime deposits are dropped out of the water. This is the lime scale which forms in pipes, heaters and on cooking utensils.
Lime accumulation not only reduces the life of equipment but also reduces efficiency of the heater and increases fuel consumption.
The usage of water softening equipment greatly reduces the hardness of the water. However, this equipment does not always remove all of the hardness (lime). For this reason it is recommended that a regular schedule for deliming be maintained.
The time between cleaning will vary from weeks to months depending upon water conditions and usage.
The depth of lime buildup should be measured periodically. Heaters equipped with cleanouts will have about 2" of lime buildup when the level of lime has reached the bottom of the cleanout opening. A schedule for deliming should then be set up,based on the amount of time it would take for a 1" buildup of lime. It is recommended that the water heater initially be inspected after 6 months.
Example 1:
Initial inspection after 6 months shows 1/2" of lime accumulation. Therefore, the heater should be delimed once a year.
Example 2:
Initial inspection after 6 months shows 2" of lime accumulation. Therefore, the heater should be delimed every 3 months.

TO FLUSH THE WATER HEATER STORAGE TANK:
1. Turn off the electrical supply to the water heater. 2. Ensure the cold water inlet valve is open. 3. Open a nearby hot water faucet and let the water run until
the water is no longer hot. Then close the hot water faucet. 4. Connect a hose to the drain valve and terminate it to an
adequate drain.

FIGURE 26.

DELIMING SOLVENTS

UN·LIME is recommended for deliming. UN·LIME is a patented food grade acid which is safe to handle and does not create the harmful fumes which are associated with other products.
UN·LIME may be obtained from your dealer, distributor or water heater manufacturer. Order Part Number 9005416105, 1 gallon, packed 4 gallons per case or Part Number 9005417105, 5 gallon container.
NOTE: Un·Lime is not available for use in Canada.
Hydrochloric base acids are not recommended for use on glass lined tanks.
Observe handling instructions on label of product being used.
TANK CLEANOUT PROCEDURE

Explosion Hazard
Flammable hydrogen gases may be present.
Keep all ignition sources away from faucet when turning on hot water.
Do not smoke or have open flame or sparks in vicinity of heater. Do not mix UN·LIME with other chemicals. Do not allow contact with magnesium, aluminum or galvanized metals.

The following practices will ensure longer life and enable the unit to operate at its designed efficiency:
1. Once a month the heater should be flushed. Open the drain valve and allow two gallons of water to drain from the heater. Inlet water valve should remain open to maintain pressure in tank.
2. A cleanout opening is provided for periodic cleaning of the tank. Gas must be shut off and heater drained before opening cleanout.
To clean heater through cleanout opening, proceed as follows:
3. Drain heater.
4. Remove outer cover plate from lower side of heater jacket.
5. Remove six (6) hex head screws securing tank cleanout plate and remove plate.
6. Remove lime, scale, or sediment using care not to damage the glass lining.
7. Inspect cleanout plate gasket, if new gasket is required, replace with part no. 9004099215.
8. Install cleanout plate. Be sure to draw plate up tight by tightening screws securely.
9. Replace outer jacket cover plate.
In some water areas the sediment might not be removed by this method and may result in the water heater making rumbling or boiling noises. To dissolve and remove these more stubborn mineral deposits, UN·LIME Professional Delimer should be used.
DELIMING USING FLO-JUG METHOD
UN·LIME in the 5 gallon size is recommended for deliming of all models. Contact your local dealer, distributor or, water heater manufacturer.
Prepare the Water Heater
To delime the water heater using the Flo-Jug method, first prepare the heater for deliming.

Chemical Hazard
· Product contains phosphoric acid.
· Keep out of reach of children.
· Use rubber or neoprene gloves.
Contains phosphoric acid. In case of external contact, flush with cool water. If irritation persists, get medical attention. If swallowed, give 1 or 2 glasses of water or milk and call physician.
Get immediate medical attention for eyes. Keep out of reach of children.
NOTE: THE USE OF RUBBER OR NEOPRENE GLOVES IS RECOMMENDED, ESPECIALLY IF YOU HAVE ANY OPEN SORES OR CUTS TO AVOID UNNECESSARY IRRITATION OR DISCOMFORT.
1. Turn off fuel and/or power supply to heater. Also, turn off power to any electrical device or equipment, which is attached, or part of the system.
2. Open hot water side of faucet closest to heater and allow water to run until it is cool enough to handle safely.
3. Close cold water inlet valve to heater.
4. Connect hose to drain valve at bottom of heater and start draining heater into suitable floor drain area.
5. Remove pressure relief valve while heater is draining. NOTE: Do not replace pressure relief valve until deliming is completed. Pressure relief valve opening will also act as a vent in case of possible contact between the delimer and the anode rod(s), which may produce flammable hydrogen-air mixtures.
6. If pressure relief valve appears to be limed-up, place it in a clean glass or plastic container adequate in size so that you can pour enough UN·LIME® into container to cover the valve and allow space for foaming. When foaming stops, run fresh cool water into the container and rinse the pressure relief valve for a few minutes.
7. If heater does not drain completely after a reasonable length of time, turn off the main water supply valve to stop water from entering the tank due to a by-pass problem or defective cold water inlet valve. Also, check for clogged drain valve opening. Heater must be completely drained before introducing UN·LIME.
8. Remove the cleanout cover and place a clean plastic bucket next to the cleanout opening.
Partially open the cold water inlet valve to allow time to accomplish the following and then close the valve.

33

While the water is being run through the tank, insert a stiff wire, copper tube flattened at one end or an opened wire coat hanger through the cleanout opening and scrape out any loose deposits of scale or sediment. This is an economical way to avoid unnecessary usage of the deliming solution.
Repeat the opening and closing of the cold water inlet valve as necessary but be sure the heater is completely drained when ready to introduce the UN·LIME.
Upon completion, reinstall the cleanout cover and use a new cleanout cover gasket (part number 9004099215).
Remove the drain valve.
9. Install the long plastic male adapter insert fitting into the drain valve opening of heater after applying Teflon tape or paste to threads. Tighten firmly by hand and use wrench or adjustable pliers to check for secure connection. Do not over tighten to avoid damage to threads and fittings.
Prepare the Up-N-Down Transfer Kit
The next step is the preparation on the Up-N-Down Transfer Kit, if you have not already done so:
1. With the 5 gallon Up-N-Down container in the vertical position, unscrew the plastic vent cap in the handle and pierce the plastic membrane over the vent boss under the cap to allow the container to vent.
Note: If your container does not have the vent cap and vent boss, drill a 3/16" hole in the handle. When you have finished deliming you will be able to plug this drilled vent with the stainless steel screw that is supplied with the kit.
2. Remove the container's cap and cut the plastic membrane located in the 3/4" IPT opening in the cap. Take care to not damage the threads.
3. Find the 3/4" male adapter, apply teflon tape to the threaded end and screw it into the 3/4" IPT opening in the cap.
4. Put cap with male adapter back on the container and slide 3/4" hose over end of male adapter and fasten in place using hose clamp provided.

FIGURE 27. PILOT BURNER At least once a year, check the pilot burner, Figure 29, and the main burner, Figure 30, for proper operation. See Figure 28 for the location of the Pilot Burner and the Main Burners. For access to pilot, unfasten two screws to burner cover and remove. Locate the burner with pilot and remove screw holding burner to manifold. Unfasten pilot tubing from valve and slide out burner and pilot. Servicing of the pilot burner includes keeping pilot free of lint, cleaning the burner head, the primary air opening and the orifice of the pilot burner.
FIGURE 28.

Delime using Flo-Jug Method

5. Slide the hose clamp over end of hose and slide hose over the male adapter in the water heater drain opening and secure in place using hose clamp.

6. Lift container to the "Pour" Position, see Figure 27, being careful to keep the vent in the handle above the liquid level and pour the UN·LIME into the heater.

7. Lower container, you may have to place the container on its empty carton to prevent the UN·LIME from flowing back into the container.
8. Let UN·LIME remain in the heater for 5 minutes and then lower the container to the "Drain" Position, see Figure 27.
9. Deliming activity is indicated by foaming on the surface of the UN·LIME. If there is deliming activity, repeat steps 6 thru 8.
Normally, lime removal will be completed within one hour. Severe build-up of lime may take longer than an hour to complete descaling.
Note: To check UN·LIME for continued use, place some scale or white chalk in a glass with a small amount of UN·LIME. If the material is vigorously dissolved by the UN·LIME, it can be reused; if not, the UN·LIME should be replaced.

FIGURE 29.
Pilot burner flame is affected by:. 1. Low gas pressure.
· Adjust pilot flame by means of the pilot gas adjustment located on the gas control valve. See Figure 31.
· The pilot flame should envelop sensing device with 5/8" (1.6cm) flame, Figure30. Remove pilot adjustment cover screw, Figure 31. Turn inner adjustment screw clockwise to decrease, or counterclockwise to increase pilot flame. Be sure to replace cover screw on gas control valve after adjustment to prevent possible gas leakage.
2. Clogged pilot burner orifice. · Clean or replace orifice. A clogged orifice will restrict gas flow.

34

Pilot sensing device must sense a flame before sparking will stop. Loose wires or a draft may cause intermittent or abnormal sparking. To eliminate this condition, first correct loose wiring condition, and then, if necessary, increase pilot flame.
MAIN BURNER
The main burner, Figure 30, should display the following characteristics:
· Cause rapid ignition and carry over of flame across entire burner.
· Give reasonably quiet operation during ignition, burning and extinction.
· Cause no excessive lifting of flame from burner ports.
If the preceding burner characteristics are not evident, check for accumulation of lint or other foreign material that restricts or other foreign material that restricts or blocks air openings to burner or heater. To clean main burners: 1. Remove main burners from unit. 2. Check that burner venturi and ports are free of foreign matter.
3. Clean burners with bristle brush and/or vacuum cleaner DO NOT distort burner ports or pilot location.
4. Reinstall burners in unit. Make sure front and rear of burners are installed correctly in burner support brackets.
Also check for good flow of combustion and ventilating air to the unit.

GAS CONTROL VALVE Figure 31 shows the two types of combination gas control valves used on these heaters. If gas control valve becomes defective, repairs should not be attempted. A new valve should be installed in place of defective one.

FOR YOUR INFORMATION

START UP CONDITIONS
SMOKE/ODOR
It is not uncommon to experience a small amount of smoke and odor during the initial start-up. This is due to burning off of oil from metal parts, and will disappear in a short while.
STRANGE SOUNDS
Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions. Condensation causes sizzling and popping within the burner area during heating and cooling periods and should be considered normal. See "Condensation" section in this manual.
CONDENSATION
Whenever the water heater is filled with cold water, some condensate will form while the burner is on. A water heater may appear to be leaking when in fact the water is condensation. This usually happens when: a. A new water heater is filled with cold water for the first time. b. Burning gas produces water vapor in water heaters,
particularly high efficiency models where flue temperatures are lower. c. Large amounts of hot water are used in a short time and the refill water in the tank is very cold. Moisture from the products of combustion condense on the cooler tank surfaces and form drops of water which may fall onto the burner or other hot surfaces to produce a "sizzling" or "frying" noise.
OPERATIONAL CONDITIONS

c. A sulfate reducing bacteria which has accumulated within the water heater (this harmless bacteria is nontoxic to humans).
d. An excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode rod.
Smelly water may be eliminated or reduced in some water heater models by replacing the anode rod(s) with one of less active material, and then chlorinating water heater tank and all water lines.
Contact the local water heater supplier or service agency for further information concerning an Anode Rod Replacement Kit and this chlorination treatment.
If smelly water persists after anode rod replacement and chlorination treatment, we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem.
Do not remove the anode rod leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.
"AIR" IN HOT WATER FAUCETS
HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet, located farthest away, be opened for several minutes before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.

HOT WATER ODOR
In each water heater there is installed at least one anode rod for
corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water. The most common complaint associated with the anode rod is one of a "rotten egg smell" in the hot water. The smell is a result of four factors which must all be present for the odor to develop:
a. A concentration of sulfate in the supply water.
b. Little or no dissolved oxygen in the water.

HIGH WATER TEMPERATURE SHUT OFF SYSTEM
This water heater is equipped with a manual reset type high limit (Energy Cutout) switch. The high limit switch interrupts the main burner gas flow should water temperature reach 203°F (95°C).
In the event of high limit switch operation, the water heater cannot be restarted unless the water temperature is reduced to approximately 120F (49C). The high limit reset button on the front of the thermostat then needs to be depressed. See Figure 2 for the location of the reset button.
