It is available from some local libraries or can be purchased from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269 as booklet ANSI/NFPA 70. Canadian installations should refer to CSA22.1, a copy can be purchased from the Canadian Standards Association, 5050 Spectrum Way, Mississauga,ONT L4W 5N6 Location Locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. Long un-insulated hot water lines can waste energy and water. Place the water heater in such a manner that the thermistor access panels can be removed to permit inspection and servicing such as checking controls. The water heater and water lines should be protected from freezing temperatures. DO NOT install the water heater in outdoor, unprotected areas. Make certain the floor underneath the water heater is strong enough to sufficiently support the weight of the water heater once it is filled with water. Floor isolation kit is recommended to minimize vibrations (where applicable). ! CAUTION: The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the water heater. NOTICE: Installation in a confined space will lead to higher power consumption if adequate ventilation is not provided. It is recommended that the hybrid water heater be installed where ambient temperatures DO NOT exceed 145°F (63°C). Insufficient air exchange will result in increased energy consumption levels. Clearances NOTICE: Auxiliary drain pan MUST conform to local codes. Drain Pan Kits are available from the store where the water heater was purchased, or any water heater distributor. Drain Pan should not B obstruct cold inlet or drain valve. Rear 0" Sides Top 3" 9" A--Diameter of water heater plus 4" min.. B--Maximum 2 To open drain, line should be at least 3/4 ID and pitched for proper drainage. A 6 Location (cont.) NOTICE: Read this page before continue. All the space area requirement specified are the unoccupied space under installation section. Unoccupied space means free air space excluding other objects like furniture, appliances or other objects that will occupy the room volume. Inspect Shipment Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the power supply corresponds to the water heater requirements. Rating plate is located on front of water heater. 7 Installing the water heater Locations that provide optimal efficiency Heater: Not Ducted Room size: Larger than 1200 ft2 (e.g. 12' x 10' x 10'). Requirements: No additional ventilation needed Heater: Not Ducted Room size: 400 ft2 (e.g. 5' x 8' x 10') - 1200 ft3 (e.g. 12' x 10' x 10'). Requirements: Full louvered door OR two louvers top and bottom1 See below. 1. Minimum louver free opening area required for not ducted room installation application will be 2.9 sq ft 2. Minimum louver free opening area required for ducted closet installation application will be 3.25 sq ft NOTICE: If air temperature in installed location drops more than 15°F (8°C) during heating, air circulation is insufficient for efficient operation. Utilize ducting to direct cold exhaust air to another location. The room size are referring to the free unoccupied space inside the room. Heater: Ducted with outlet duct Room size: For all closet installation (size smaller than 400 ft3). Requirements: Full louvered door2. 8 NOTICE: The inlet and outlet water nipple remain with the black markings pointed up. Thermal Expansion Determine if a check valve exists in the inlet water line. Check with your local water utility. It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the cold water inlet line can cause what is referred to as a "closed water system". A cold water inlet line with no check valve or back flow prevention device is referred to as an "open" water system. As water is heated, it expands in volume and creates an increase in the pressure within the water system. This action is referred to as "thermal expansion". In an "open" water system, expanding water which exceeds the capacity of the water heater flows back into the city main where the pressure is easily dissipated. A "closed water system", however, prevents the expanding water from flowing back into the main supply line, and the result of "thermal expansion" can create a rapid and dangerous pressure increase in the Water Supply Connections Refer to the illustration on the next page for suggested typical installation. The installation of flexible connectors is recommended on the hot and cold water connections. Flexible connections provide vibration isolation and allow the water heater to be easily disconnected for servicing if necessary. The HOT and COLD water connections are clearly marked and are 3/4in. NPT on all models. Install a shut-off valve in the cold water line near the water heater. See page 9 on "To Fill The Water Heater". water heater and system piping. This rapid pressure increase can quickly reach the safety setting of the relief valve, causing it to operate during each heating cycle. Thermal expansion, and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve, and possibly the heater itself. Replacing the relief valve WILL NOT correct the problem! The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between the water heater and the check valve (refer to the illustration on the next page). The expansion tank is designed with an air cushion built in that compresses as the system pressure increases, thereby relieving the over pressure condition and eliminating the repeated operation of the relief valve. Other methods of controlling thermal expansion are also available. Contact your installing contractor, water supplier or plumbing inspector for additional information regarding this subject. NOTICE: DO NOT apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting adapter to the water connections on heater. Any heat applied to the water supply fittings will permanently damage the dip tube and/or heat traps. Condensate Drains NOTICE: Condensate from this unit is not Acidic and is not required to be neutralized. Consult local codes or ordinances for specific requirements. Refer to page 5. IMPORTANT: When making drain fitting connections to the drain tubing, use a thin layer of piping tape or silicone and install hand tight. · All drain lines must be pitched downward away from the unit a minimum of 1/8" per foot of line to ensure proper drainage. · Drain lines must include a P-trap if connected to a sewer pipe. IMPORTANT: When making drain fitting · If no drain is available, then a common connections to the drain tubing, DO NOT condensate pump with a capacity no overtighten.

WARNING: The pressure rating of the relief valve must not exceed 150 PSI, the maximum working pressure of the water heater as marked on the rating plate. Relief Valve The btu/h rating of the relief valve must not be less than the input rating of the water heater as indicated on the rating label located on the front of the heater (1 watt=3.412 btu/h). Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts or persons and to eliminate potential water damage. Piping used should be of a type approved for hot water distribution. The discharge line must be no smaller than the outlet of the valve and must pitch downward from the valve to allow complete drainage (by gravity) of the relief valve and discharge line. The end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in the discharge line. !

WARNING: If local codes require external application of insulation blanket kits the manufacturer's instructions included with the kit must be carefully followed. Insulation Blankets Insulation blankets, available to the general public, for external use on electric water heaters are not necessary. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. This water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements making an insulation blanket unnecessary. The manufacturer's warranty does not cover any damage or defect caused by installation, attachment or use of any type of energy saving or other unapproved devices (other than those authorized by the manufacturer) into, onto or in conjunction with the water heater. The use of unauthorized energy saving devices may shorten the life of the water heater and may endanger life and property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices. ! CAUTION: If local codes require the application of an external insulation blanket to this water heater, pay careful attention to the following so as not to restrict the proper function and operation of the water heater: DO NOT cover the operating or warning labels attached to the water heater or attempt to relocate them on the exterior of insulation blanket. DO NOT cover air openings of the water heater . DO NOT cover the Controller Assembly, temperature and pressure relief valve or drain valve. Inspect the insulation blanket frequently. Vertical Flexible Filter Air filter must be accessible Controller Assembly Air Outlet Opening 12 Hot and Cold Pipe Insulation Installation Install the insulation on the cold water supply inlet and the hot water outlet as shown in the illustration. Hot Water Outlet Relief Valve Cold Water Inlet Drain Valve 13 Installing the water heater Ducting Requirements Always check with local building and HVAC codes before designing the duct system The water heater may be ducted to the outdoors or another space as described in these instructions. Ducting configurations that does not comply with these guidelines are not supported. DO NOT connect this water heater to existing duct work; it must be ducted separately from other appliances. Ducting approved for HVAC applications is required. Ducting must be adequately supported along both vertical and horizontal lengths. UL Certified terminations must be used for ducting to the outside. These terminations have been evaluated to ensure there is sufficient protection from rain water entry and resistance to air flow is minimized. Indoor registers approved for HVAC applications is required. Rigid ducting must be isolated from floor joists or other structural members to minimize the transmission of noise and vibration. A short section (12 inch minimum) of flexible duct must be used between the water heater and rigid ducting as an isolation method. Every foot of flexible ducting counts as three feet of rigid ducting. Ducting must be insulated per HVAC codes (to prevent condensation). Ensure cold air exhaust is sufficiently away from structures to prevent condensation on surfaces. Maximum heater performance is obtained by lowering the resistance to air flow (regular filter maintenance is beneficial) and providing the unit with warm moist air. Considerations when planning the duct system: Run the ducting the most direct route possible. Limit the number of elbows/bends. Use the largest duct size possible. Use the largest termination possible. Consider placement and direction of terminations (reduce recirculation of exhaust into the intake). Calculated length of duct is the length on the inlet plus the length on the outlet. Any combination of duct lengths on the inlet and outlet is supported up to the maximum duct length (Table 1). Duct System Configuration 8, 7, 6 and 5 inch diameter ducting is supported. Table 1 lists the total feet of ducting allowed. For duct diameters smaller than 8 inch diameter, Table 1 takes into account the duct reducer(s) and up to 10 feet of 8 inch rigid ducting (two elbows) before the duct reducer(s) at the unit.Duct Reducers must be installed within 10 feet (two elbows) of the unit or within 2 feet of the end of the duct. Table 1.- Maximum Duct Length. Duct Type / Diameter 8" 7" 6" 5" Rigid Flexible 340' 160' 65' 17' 125' 65' 25' -- 14 Equivalent feet for Duct Accessories Elbows/Bends Rigid duct elbows and flex bends greater than 45° is considered an elbow. Flexible ducting bends' inner radius cannot be less than its diameter. If bends with tighter radiuses are needed, a rigid elbow must be used. Maximum number of elbows/bends allowed are shown in [brackets] in Table 2. Terminations/Registers Table 2 equivalent feet for terminations includes the rodent screen. For terminations and registers with smaller diameters than the duct diameter, Table 2 accounts for the duct reducer and termination/register. Smaller diameter terminations and registers with more than a 2 ft. connection is not supported. Damper If ducting to the outside using an exhaust duct only (no intake duct), an approved Rheem damper should be installed no further than 10 ft. of rigid ducting total (two elbows equivalent) from the unit. This prevents outside air from coming into the living space. If ducting air from the outside to the inlet of the heater, no provision is made to prevent outside air from flowing into the living space. Table 2.- Equivalent feet for Duct Accessories.

HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water begins to flow. DO NOT smoke or use an open flame near the faucet at the time it is open. Safety Precautions Disconnect all power to water heater if it has been subjected to over heating, fire, flood, physical damage. DO NOT turn on water heater unless it is filled with water. DO NOT turn on water heater if cold water supply shut-off valve is closed. If there is any difficulty in understanding or following the Operating Instructions or the Care and Cleaning section, it is recommended that a qualified person or serviceman perform the work. WARNING: If the water heater has been subjected to fire, flood or physical damage, disconnect all power to water heater, and DO NOT operate the water heater again until it has been checked by a qualified service technician. NOTICE: DO NOT use this appliance if any part has been under water. Immediately call a qualified installer or service agency to replace a flooded water heater. DO NOT attempt to repair the unit! It must be replaced. Safety Controls The water heater is equipped with a temperature limiting control (ECO) that is located in upper cavity cover in contact with the tank surface. If for any reason the water temperature becomes excessively high, the temperature limiting control (ECO) breaks the power circuit to the heating system. Once the control opens, it must be reset manually. CAUTION: The cause of the high temperature condition must be investigated by qualified service technician and corrective action must be taken before placing the water heater in service again. To reset the temperature limiting control: (Refer to Illustration in Cavity Insert section): Disconnect all power to unit before starting maintenance. Remove the upper cavity cover and insulation. Press the red RESET button. Replace the insulation, jacket access panel and plastic housing before turning on the power to the water heater. Water Temperature Setting ! DANGER: There is a hot water scald potential if the thermostat is set too high. Households with small children, disabled, or elderly persons may require a 120°F (49°C) or lower thermostat setting to prevent contact with HOT water. The temperature of the water in the water heater can be regulated by selecting the desired temperature on control display. Safety and energy conservation are factors to be considered when selecting the water temperature setting of the water heater. The lower the temperature setting, the greater the savings in energy and operating costs. To comply with safety regulations the temperature is factory set at 120°F (49°C) or less where local codes require. This is the recommended starting point. Water temperatures above 125°F (52°C) can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined in this manual and on the label on the water heater. This label is located on the front of the water heater. Mixing valves are recommended for reducing point of use water temperature by mixing hot and cold water in branch water lines. It is recommended that a mixing valve complying with the Standard for Temperature Actuated Mixing Valves for Hot Water Distribution Systems, ASSE 1017 be installed. See page 3 for more details and contact a licensed plumber or the local plumbing authority for further information. When used in demand response applications a thermostatic mixing valve conforming to ASSE 1017 shall be installed on the hot water supply line following all manufacturer installation instructions. See page 32 for additional installation information. The chart on the page 3 may be used as a guide in determining the proper water temperature for your home. 19 Local Startup User Interface Current Mode Fault Indicator Temp & Value Adjustment Current Alarm & History Scroll Available Current Set Point Scald Warning Mode Toggle Next Screen / Option Text Display Enable/Disable Clear Alarm Enter / Select WiFi Setup & Indicator ICONS show the current state of the entire system. 1.

DANGER: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage. In order to drain the water heater, turn off the cold water supply. Open a hot water faucet or lift the handle on the relief valve to admit air to the tank. Attach a garden hose to the drain valve on the water heater and direct the stream of water to a drain. Open the valve. DANGER: Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with the hot water released by the valve. The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage. NOTICE: If the temperature and pressure relief valve on the water heater discharges periodically, this may be due to thermal expansion in a closed water system. Contact the water supplier or your plumbing contractor on how to correct this. DO NOT plug the relief valve outlet. Routine Preventative Maintenance Properly maintained, your water heater will provide years of dependable trouble-free service. It is suggested that a routine preventive maintenance program be established and followed by the user. Most electrical appliances, even when new, make some sound when in operation. If the hissing or singing sound level increases excessively, Contact a qualified installer or plumbing contractor to inspect. IMPORTANT: See "DANGER on left". At least once a year, lift and release the lever handle on the temperature pressure relief valve, located on the side of the water heater, to make certain the valve operates freely. Allow several gallons to flush through the discharge line to an open drain. It is recommended to clean the filter on top of the heat pump when "Clean filter reminder" alert appears. Clean by washing with mild detergent and water. Dry and replace. Remove the filter by lifting up, then replace by lowering back into the filter slot on top of the unit. See Figure below. At least once a year pour a cup of bleach in the access opening of the condensate drain to kill any algae, mold, or mildew that has formed in the pipe. Ensure the condensate can flow freely; unclog if needed. A water heater's tank can act as a setting basin for solids suspended in the water. It is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank. It is suggested that a few quarts of water be drained from the water heater's tank every month to clean the tank of these deposits. Rapid closing of faucets or solenoid valves in automatic water using appliances can cause a banging noise heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can be used to minimize the problem. Vertical Flexible Filters Filter Handle 26 Care and cleaning of the water heater NOTICE: Refer to the Hydrogen Gas Caution in the Operating Instructions. Vacation and Extended Shut-Down If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off to conserve energy and prevent a build-up of dangerous hydrogen gas. After a long shut-down period, the water heater's operation and controls should be checked by qualified service personnel. Make certain the water heater is completely filled again before placing it in operation. The water heater and piping should be drained if they might be subjected to freezing temperatures. NOTICE: DO NOT remove the anode rod from the water heater's tank. Operation with the anode rod removed will greatly shorten the life of the glass lined tank and will exclude warranty coverage. Anode Rod This water heater is equipped with an anode rod designed to prolong the life of the glass-lined tank. The anode rod is slowly consumed, thereby eliminating or minimizing corrosion of the glasslined tank. Water sometimes contains a high sulfate and/or mineral content and together with cathodic protection process can produce a hydrogen sulfide, or rotten egg odor in the heated water. Chlorination of the water supply should minimize the problem. 27 Before You Call For Service... Troubleshooting Tips Save time and money! Review the chart on this page first and you may not need to call for service. Problem Rumbling noise Possible Causes Water conditions in your home caused a build up of scale or mineral deposits in the water heater. What to Do Allow a few quarts of water to run from drain valve to remove sediment settlings.
