2. Heaters are designed for use in heating applications with ambient startup temperatures between -40°F and 90°F and ambient operating temperatures between 40°F and 90°F.
3. Do not install unit outdoors. 4. In garages or other sections of aircraft hangars such
as offices and shops that communicate with areas used for servicing or storage, keep the bottom of the unit at least 7′ above the floor unless the unit is properly guarded. In parking garages, the unit must be installed in accordance with the standard for parking structures ANSI/NFPA 88A latest edition, and in repair garages the standard for repair garages NFPA 30A – latest edition (formerly NFPA 88B). In Canada, installation of heaters in airplane hangars must be in accordance with the requirements of the enforcing authority, and in public garages in accordance with the current CSA-B149 codes. 5. In aircraft hangars, keep the bottom of the unit at least 10′ from the highest surface of the wings or engine enclosure of the highest aircraft housed in the hangars and in accordance with the requirements of the enforcing authority and/or NFPA 409 latest edition. 6. Installation of units in high humidity or salt water atmospheres will cause accelerated corrosion resulting in a reduction of the normal life of the units.

To prevent premature heat exchanger failure, do not locate ANY gas-fired appliances in areas where corrosive vapors (i.e. chlorinated, halogenated or acidic) are present in the atmosphere.
Location Recommendations 1. When locating the heater, consider general space and
heating requirements, availability of gas and electrical supply, and proximity to vent locations.

Combustion Air Requirements The National Fuel Gas Code defines an “unconfined space” as a space whose volume is greater than 50 cubic feet per 1,000 Btu/Hr input of the installed appliance(s). A confined space is 50 cubic feet or less per 1,000 Btu/Hr input of the installed appliance(s).

2. Avoid installing units in extremely drafty locations. Drafts can cause burner flames to impinge on heat exchangers which shortens life. Maintain separation between units so discharge from one unit will not be directed into the inlet of another.
3. Be sure the structural support at the unit location site is adequate to support the unit’s weight. For proper operation the unit must be installed in a level horizontal position.
4. Do not install units in locations where the flue products can be drawn into the adjacent building openings such as windows, fresh air intakes, etc.
5. Be sure that the minimum clearances to combustible materials and recommended service clearances are maintained. Units are designed for installation on noncombustible surfaces with the minimum clearances shown in Figure 4.1 and Tables 4.1 and 4.2.
6. Units exposed to inlet air temperatures of 40°F or less, may experience condensation, therefore, provisions should be made for disposal of condensate.
7. When locating units, it is important to consider that the exhaust vent piping must be connected to the outside atmosphere.
8. Maximum equivalent vent lengths are listed in “Section A General Instruction – All Units” of the Venting Instructions.

Units installed in tightly sealed buildings or confined spaces must be provided with two permanent openings, one near the top of the confined space and one near the bottom. Each opening should have a free area of not less than one square inch per 1,000 BTU per hour of the total input rating off all units in the enclosure, freely communicating with interior areas having, in turn adequate infiltration from the outside.
For further details on supplying combustion air to a confined (tightly sealed) space or unconfined space, see the National Fuel Gas Code ANSI Z223.1 (NFPA 54) or CSA-B149.1 Installation Code – latest edition.
Sound and Vibration Levels All standard mechanical equipment generates some sound and vibration that may require attenuation. Libraries, private offices and hospital facilities will require more attenuation, and in such cases, an acoustical consultant may be retained to assist in the application. Locating the equipment away from the critical area is desirable within ducting limitations. Generally, a unit should be located within 15′ of a primary support beam. Smaller deflections typically result in reduced vibration and noise transmission.

6-580.21

INSTALLATION

UNIT MOUNTING

1. Be sure the means of suspension is adequate to support the weight of the unit (see pages 25 and 26 for unit weights).
2. For proper operation and to assure that flames are directed into the center of the heat exchanger tubes, the unit must be installed in a level horizontal position. Use a spirit level to ensure that the unit is suspended correctly.
3. Clearances to combustibles as specified in Figure 4.1 and Tables 4.1 and 4.2 must be strictly maintained.
4. All standard units are shipped fully boxed. Larger units are also supplied with skid supports on the bottom of the box. The larger units may be lifted from the bottom by means of a fork lift or other lifting device only if the shipping support skids are left in place and the forks support the whole depth of the unit. If the unit must be lifted from the bottom for final installation without the carton in place, be sure to properly support the unit over its entire length and width to prevent damage. When lifting units, make sure the load is balanced.
5. Propeller models up to size 350 have 2 mounting holes, size 350 and above have 4 mounting holes and blower models up to size 350 have 4 mounting holes, size 350 and above have 6 mounting holes. Units with two point suspension incorporate a level hanging feature. Depending on what options and accessories are being used, the heater may not hang level as recieved from the factory. Do not hang heaters with deflector hoods until referring to the “Installation Manual for Deflector Hoods” and making the recommended preliminary adjustments on the heater, while the heater is resting on the floor. The units can be mounted with 3/8″-16 threaded rod as follows:
· On each piece of threaded rod used, screw a nut a distance of about 1″ onto the end of the threaded rods that will be screwed into the unit heater.
· Place a washer over the end of the threaded rod and screw the threaded rod into the unit heater weld nuts on the top of the heater at least 5 turns, and no more than 10 turns. Tighten the nut first installed onto the threaded rod to prevent the rod from turning.
· Drill holes into a steel channel or angle iron at the same center-line dimensions as the heater that is being installed. The steel channels or angle iron pieces need to span and be fastened to appropriate structural members.
· Cut the threaded rods to the preferred length, place them through the holes in the steel channel or angle iron and secure with washers and lock nuts or lock washers and nuts. A double nut arrangement can be used here instead of at the unit heater (a double nut can be used both places but is not necessary).
· Do not install standard unit heaters above the maximum mounting height shown in Table 20.1.
NOTE: A pipe hanger adapter kit, shown in Figure 5.2, is available as an accessory. One kit consists of drilled 3/4″ IPS pipe caps and 3/8″ – 16 x 1-3/4″ capscrews to facilitate threaded pipe suspension.

CAUTION

Installation must conform with local building codes or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) – latest edition. In Canada installation must be in accordance with CSA B149.1.

Model PDP and BDP unit heaters must be vented with the proper passageway as described in these instructions to convey flue gases from the unit or the vent connector to the outside atmosphere.
The venting instructions are organized in sections, based on installation type. The sections are identified as follows:

Instructions

Applicable Installation Instructions by Vent System Type

General Instructions for ALL Installations

VERTICAL CATEGORY I vent systems j

HORIZONTAL CATEGORY III vent systems k

The differences between vertical and horizontal vent systems will be identified in “Section A – General Instructions – All Units”.
Section A – General Instructions – All Units

A1. If the unit heater being installed is replacing existing equipment and using the existing vent system from that equipment, inspect the venting system for proper size and horizontal pitch, as required in the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) or CSA B149.1 Installation Code latest edition and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies, which could cause an unsafe condition.
A2. The vent pipe should be galvanized steel or other suitable corrosion resistant material. Follow the National Fuel Gas Code for minimum thickness of vent material. The minimum thickness for connectors varies depending on the pipe diameter. Do not vent unit with PVC or other forms of plastic venting material.
A3. All heaters come with a vent adapter for attaching the vent pipe to the heater (see Table 6.1). Attach the vent pipe to the adapter with 3 corrosion resistant screws. (Drill pilot holes through the vent pipe and adapter prior to screwing in place). Vent pipe must not be smaller than the connector size.
A4. Limit the total equivalent vent pipe length to fall between the minimum and maximum equivalent vent lengths given

in Table 6.1, making the vent system as straight as possible. The equivalent length of a 5″ elbow is 6′ and for a 6″ elbow is 7′.
A5. A minimum of 12″ straight pipe is recommended from the flue outlet before turns in the vent pipe.
A6. Horizontal sections of vent pipe are to be installed with an upward or downward slope from the appliance of 1/4″ per foot and suspended securely from overhead structures at points not greater than 3′ apart.
A7. Fasten individual lengths of vent together with at least 3 corrosion resistant sheet metal screws.
A8. Keep single wall vent pipe at least 6″ from combustible materials. For double wall vent pipe, follow the vent pipe manufacturer’s clearances to combustibles. The minimum distance from combustible materials is based on the combustible material surface not exceeding 160°F. Clearance from the vent pipe (or the top of the unit) may be required to be greater than 6″ if heat damage other than fire could result (such as material distortion or discoloration).
A9. Avoid venting through unheated space when possible. When venting does pass through an unheated space or if the unit is installed in an environment that promotes condensation, insulate runs greater than 5′ to minimize condensation. Inspect for leakage prior to insulating and use insulation that is noncombustible with a rating of not less than 400°F. Install a tee fitting at the low point of the vent system and provide a drip leg with a clean out cap as shown in Figure 9.1.

INSTALLATION – VENTING
A10. When the vent passes through a combustible INTERIOR wall or floor, a metal thimble 4″ greater than the vent diameter is necessary. If there is 6′ or more of vent pipe in the open space between the appliance and where the vent pipe passes through the wall or floor, the thimble need only be 2″ greater than the diameter of the vent pipe. If a thimble is not used, all combustible material must be cut away to provide 6″ of clearance. Where authorities have jurisdiction, Type B vent may be used for the last section of vent pipe to maintain clearance to combustibles while passing through wall or floor. See Figure 6.1. Any material used to close the opening must be noncombustible.
A11. Seal all seams and joints of un-gasketed single wall pipe with metal tape or Silastic suitable for temperatures up to 400°F. Wrap the tape 2 full turns around the vent pipe. One continuous section of double wall vent pipe may be used within the vent system to pass through the wall to the listed vent cap. Refer to instruction A12 in “Section A General Instructions All Units” for attaching double wall pipe to single wall pipe.

A12. The following are general instructions for double wall (Type B) terminal pipe installation.
How to attach a single wall vent terminal to double wall (Type B) vent pipe:
1. Look for the “flow” arrow on the vent pipe.
2. Slide the vent terminal inside the exhaust end of the double wall vent pipe.
3. Drill 3 holes through the pipe and the vent terminal. Using 3/4″ long sheet metal screws, attach the cap to the pipe. Do not over tighten.
How to connect a single wall vent system to a double wall (Type B) vent pipe:
1. Slide the single wall pipe inside the inner wall of the double wall pipe.
2. Drill 3 holes through both walls of the single and double wall vent pipes. Using 3/4″ sheet metal screws, attach the 2 pieces of pipe. Do not over tighten.
3. The gap between the single and double wall pipe must be sealed but it is not necessary to fill the full volume of the annular area. To seal, run a large bead of 400°F silastic around the gap.
A13. Vent termination clearances must be maintained:

B7. Use a listed vent terminal to reduce down drafts and moisture in the vent.
B8. Double wall vent pipe is recommended, although single wall can be used if the requirements of the National Fuel Gas Code are followed.
B9. Vertical vents must terminate a minimum horizontal and vertical distance from roof lines and adjacent walls or obstructions. These minimum distances are outlined as follows (based on National Fuel Gas Code requirements for vents with diameters less than 12″):
· For double wall vent pipe and 8′ or greater horizontal distance to any vertical wall or similar obstruction, the vent must terminate above the roof in accordance with Figure 9.1 and Table 9.1.
· For double wall vent pipe and less than 8′ horizontal distance to any vertical wall or similar obstruction, the vent must terminate at least 2′ above the highest point where it passes through a roof of a building and at least 2′ higher than any portion of a building within a horizontal distance of 10′ (see Figure 9.1).

INSTALLATION – VENTING
Section C Horizontal, Category III Vent System
Installation
C1. This section applies to horizontally vented Category III vent systems and is in addition to “Section A General Instructions All Units”.
C2. Horizontal vent systems terminate horizontally (sideways).
C3. Seal all seams and joints of un-gasketed single wall pipe with metal tape or Silastic suitable for temperatures up to 400°F. Wrap the tape 2 full turns around the vent pipe. For single wall vent systems, 1 continuous section of double wall vent pipe may be used within the vent system to pass through the wall to the listed vent cap. Under no circumstances should two sections of double wall vent pipe be joined together within one horizontal vent system due to the inability to verify complete seal of inner pipes. Category III vent systems listed by a nationally recognized agency and matching the diameters specified may be used. Different brands of vent pipe materials may not be intermixed. Refer to instruction A10 in “Section A General Instructions All Units” for attaching double wall pipe to single wall pipe.
C4. Refer to Table 6.1 for total minimum and maximum vent lengths, making the system as straight as possible. The equivalent length of a 90° elbow is 6′ for 5″ diameter and 7′ for 6″ diameter.
C5. All horizontal Category III vents must be terminated with a listed vent cap. The cap must terminate a minimum distance beyond the exterior wall surface as shown in Figure 10.2 and Table 10.1. The vent must be supported as shown in Figure 10.1. Precautions must be taken to prevent degradation of building materials by flue products.

GAS CONNECTIONS
WARNING
1. All field gas piping must be pressure/leak tested prior to operation. Never use an open flame. Use a soap solution or equivalent for testing.
2. Gas pressure to appliance controls must never exceed 14″ W.C. (1/2 psi).
3. To reduce the opportunity for condensation, the minimum sea level input to the appliance, as indicated on the serial plate, must not be less than 5% below the rated input, or 5% below the minimum rated input of dual rated units.

Figure 11.1 – Recommended Sediment Trap/Manual Shut-off Valve Installation for Gas Connection
j

CAUTION
1. Purging of air from gas lines should be performed as described in the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) – latest edition or in Canada CSA-B149 codes.
2. When leak testing the gas supply piping system, the appliance and its combination gas control must be isolated during any pressure testing in excess of 14″ W.C. (1/2 psi).
3. The unit should be isolated from the gas supply piping system by closing its field installed manual shut-off valve. This manual shut-off valve should be located within 6′ of the heater.
4. Turn off all gas before installing appliance.
IMPORTANT
To prevent premature heat exchanger failure, the input to the appliance, as indicated on the serial plate, must not exceed the rated input by more than 5%.
1. Installation of piping must conform with local building codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) – Latest Edition. In Canada, installation must be in accordance with CSA-B149.1.
2. Piping to units should conform with local and national requirements for type and volume of gas handled, and pressure drop allowed in the line. Refer to Table 11.1 to determine the cubic feet per hour (cfh) for the type of gas and size of unit to be installed. Using this cfh value and the length of pipe necessary, determine the pipe diameter from Table 11.2. Where several units are served by the same main, the total capacity, cfh and length of main must be considered. Avoid pipe sizes smaller than 1/2″. Table 11.1 allows for a 0.3″ W.C. pressure drop in the supply pressure from the building main to the unit. The inlet pressure to the unit must be 6-7″ W.C. for natural gas and 11-14″ W.C. for propane gas. When sizing the inlet gas pipe diameter, make sure that the unit supply pressure can be met after the 0.3″ W.C. has been subtracted. If the 0.3″ W.C. pressure drop is too high, refer to the Gas Engineer’s Handbook for other gas pipe capacities.
3. Install a ground joint union with brass seat and a manual shut-off valve adjacent to the unit for emergency shut-off and easy servicing of controls, including a 1/8″ NPT plugged tapping accessible for test gauge connection (see Figure 11.1).
4. Use 2 wrenches when connecting field piping to units. 5. Provide a sediment trap before each unit and in the line
where low spots cannot be avoided (see Figure 11.1). 6. When pressure/leak testing, pressures above 14″ W.C.
(1/2 psi), close the field installed shut-off valve, disconnect the appliance and its combination gas control from the gas supply line, and plug the supply line before testing. When testing pressures 14″ W.C. (1/2 psi) or below, close the manual shut-off valve on the appliance before testing.

j Manual shut-off valve is in the “OFF” position when handle is perpendicular to pipe.

INSTALLATION – HIGH ALTITUDE ACCESSORY KIT

HIGH ALTITUDE ACCESSORY KIT
Modine’s gas-fired equipment standard input ratings are certified by ETL. For elevations above 2,000′, ANSI Z223.1 requires ratings be reduced 4 percent for each 1000′ above sea level. For units in Canada, CSA requires that ratings be reduced 10 percent at elevations above 2,000′. The high altitude adjustment instructions and pressure switch kits listed in this manual are for use with units that will be installed over 2,000′ These methods and kits comply with both ANSI Z223.1 and CSA requirements.
If a unit is to be installed at higher elevations AND converted from natural gas to propane gas operation, a propane conversion kit must be used in conjunction with the pressure adjustment methods and pressure switch kits listed herein. For the Selection and Installation Instructions for propane conversion kits, please see the latest revision of Modine Manual 75-511.
Selection of the Proper Pressure and Kit
To determine the proper manifold pressure at altitude and if required, the proper combustion air pressure switch kit, the full model number of the heater, the fuel to be used, and the altitude the unit will be installed at must be known. Refer to the unit serial plate or carton label to obtain the necessary information about the unit.
After obtaining this information, refer to the gas pressure and selection charts shown in Tables 12.1 through 13.1. The pressure charts are differentiated by elevation, fuel type, and country the product is being installed in. The selection charts are differentiated by product type, altitude and fuel type. If converting from natural gas to propane gas and operation at high altitude, both a propane conversion kit and a pressure switch kit must be used (if applicable). Selection

charts include the proper kit suffix, when required.
Manifold Pressure Adjustment
The inlet pressure to the unit must be confirmed to be within acceptable limits (6-7″ W.C. for natural gas and 11-14″ W.C. for propane gas) before opening the shutoff valve or the combination gas valve may be damaged.
Heaters for use with natural gas have gas valves that need to be feild set at 3.5″ W.C. manifold pressure at 7.0″ W.C. inlet pressure.
Units for use with propane gas need to be feild set for 10.0″ W.C. manifold pressure at 14.0″ W.C. inlet pressure.
Installation above 2,000′. elevation requires adjustment of the manifold pressure as described.
Derated BTU Content Gas and Manifold Pressure Calculation
Some utility companies may derate the BTU content (heating value) of the gas provided at altitude to a value other than 1,050 BTU/ft3 for natural gas or 2,500 BTU/ft3 for propane gas to allow certain heating appliances to be used with no manifold pressure adjustments. For this reason it is necessary that the supplying utility be contacted for detailed information about the gas type and BTU content (heating value) before operating any heater. Tables 12.1 and 12.2 show the standard derated heating values (4% per 1,000′ of elevation in the USA and 10% between 2,001′ and 4,500′ elevation in Canada) of natural and propane gases at various altitudes. If the utility is supplying gas with heating values as shown in Tables 12.1 and 12.2, the manifold pressure should be set to 3.5″ W.C for natural gas and 10.0″ W.C. for propane gas.
NOTE: Only the high fire gas pressure need be adjusted, low fire gas pressure should remain the same.

INSTALLATION
ELECTRICAL CONNECTIONS
WARNING
1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.
2. All appliances must be wired strictly in accordance with wiring diagram furnished with the appliance. Any wiring different from the wiring diagram could result in a hazard to persons and property.
3. Any original factory wiring that requires replacement must be replaced with wiring material having a temperature rating of at least 105°C.
4. Ensure that the supply voltage to the appliance, as indicated on the serial plate, is not 5% greater than rated voltage.
CAUTION
Ensure that the supply voltage to the appliance, as indicated on the serial plate, is not 5% less than the rated voltage.
1. Installation of wiring must conform with local building codes, or in the absence of local codes, with the National Electric Code ANSI/NFPA 70 – Latest Edition. Unit must be electrically grounded in conformance to this code. In Canada, wiring must comply with CSA C22.1, Part 1, Electrical Code.
2. Two copies of the unit wiring diagram are provided with each unit. One is located in the electrical junction box and the other is suppled in the literature packet. Refer to this diagram for all wiring connections.
3. Make sure all multi-voltage components (motors, transformers, etc.) are wired in accordance with the power supply voltage.
4. The power supply to the unit must be protected with a fused or circuit breaker switch.
5. The power supply must be within 10 percent of the voltage rating and each phase must be balanced within 2 percent of each other. If not, advise the utility company.
6. External electrical service connections that must be installed include:
a. Supply power connection (120, 208, 240, 480, or 575 volts).
b. Thermostats, summer/winter switches, or other accessory control devices that may be supplied (24 volts).
NOTE: Certain units will require the use of a field step-down transformer. Refer to the serial plate to determine the unit supply voltage required.
7. Refer to Figure 19.1 for the electrical junction box locations.
8. All supply power electrical connections are made in the electrical junction box of the unit. The low voltage (thermostat and accessory control devices) can be wired to the terminals on the electrical junction box. Refer to the wiring diagram for the terminal location of all low voltage wiring.

DUCT INSTALLATION
IMPORTANT
Do not attempt to attach ductwork of any kind to propeller models.
When installing the heater, always follow good duct design practices for even distribution of the air across the heat exchanger. Recommended layouts are shown in Figure 14.1. When installing blower units with ductwork the following must be done.
1. Provide uniform air distribution over the heat exchanger. Use turning vanes where required (see Figure 14.1).
2. Provide removable access panels in the ductwork on the downstream side of the unit heater. These openings should be large enough to view smoke or reflect light inside the casing to indicate leaks in the heat exchanger and to check for hot spots on exchanger due to poor air distribution or lack of sufficient air.
3. If ductwork is connected to the rear of the unit use a Modine blower enclosure kit or if using a field designed enclosure maintain dimensions of the blower enclosure as shown on page 26.

Additional Requirements for Blower Model BDP
Determining Blower Speed The drive assembly and motor on all blower units are factory assembled and adjusted for operation under average conditions of air flow and without any external static pressure. The motor sheave should be adjusted as required when the unit is to be operated at other than average air flows and/or with external static pressures. Adjustment must always be within the performance range shown on page 20 and the temperature rise range shown on the unit’s rating plate.
To determine the proper blower speed and motor sheave turns open, the operating conditions must be known. For example, a model BDP350 unit, operating with no external static pressure, (e.g. no ductwork, nozzles, etc.) is to deliver an air volume of 6481 cfm (cfm = cubic feet per minute). This requires the unit be supplied with a 5 hp motor, a -207 drive, and the drive sheave set at 2.5 turns open to achieve a blower speed of 960

6-580.21

INSTALLATION
rpm (see performance table for units with or without blower enclosure, page 21). See “Blower Adjustments” for setting of drive pulley turns open.
If a blower unit is to be used with ductwork or nozzles, etc., the total external static pressure under which the unit is to operate, and the required air flow must be known before the unit can be properly adjusted. Any device added externally to the unit, and which the air must pass through, causes a resistance to air flow called pressure loss.
If Modine filters are used, the pressure loss through the filters is included in the performance data on page 21. If Modine supplied discharge nozzles are used, the pressure drop of the nozzles can be found footnoted at the bottom of page 24. If filters, nozzles or ductwork are to be used with the unit, and they are not supplied by Modine, the design engineer or installing contractor must determine the pressure loss for the externally added devices or ductwork to arrive at the total external static pressure under which the unit is to operate.
Once the total static pressure and the required air flow are known, the operating speed of the blower can be determined and the correct motor sheave adjustments made. As an example, a model BDP350 is to be used with a Modine supplied blower enclosure and filters attached to ductwork by others. The unit is to move 6481 cfm of air flow against an external static pressure of 0.2″ W.C, which must be added for the filter pressure drop for a total of 0.4″ W.C. total pressure drop. The performance table on page 21 for a BDP350, at 6481 cfm and 0.4″ W.C. static pressure, shows that the unit will require a 5 hp motor using a -207 drive, and the motor sheave should be set at .5 turns open to achieve a blower speed of 1050 rpm.
To Install 1. Remove and discard the motor tie down strap and the
shipping block beneath the belt tension adjusting screw (Not used on all models.)
2. For 3 and 5 HP motors, affix sheave to the motor shaft and install motor on the motor mounting bracket. Install belt on blower and motor sheaves.

Figure 15.1 – Blower Model
THREADED MOUNTING BRACKETS ON BLOWER ASSEMBLY

MOTOR MOUNTING BRACKET

3. Adjust motor adjusting screw for a belt deflection of approximately 3/4″ with five pounds of force applied midway between the sheaves (see Figure 15.3). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension. Excessive tension will cause bearing wear and noise.
4. The blower bearings are lubricated for life; however, before initial unit operation the blower shaft should be lubricated at the bearings with SAE 20 oil. This will reduce initial friction and start the plastic lubricant flowing.
5. Make electrical connections as outlined in the section “Electrical Connections” on page 14.

Blower Adjustments

Following electrical connections, check blower rotation to assure blow-through heating. If necessary interchange wiring to reverse blower rotation. Start fan motor and check blower sheave RPM with a hand-held or strobe-type tachometer. RPM should check out with the speeds listed in “Performance Data” shown on page 21. A single-speed motor with an adjustable motor sheave is supplied with these units. If blower fan speed changes are required, adjust motor sheave as follows:
NOTE: Do not fire unit until blower adjustment has been made or unit may cycle on limit (overheat) control.
1. Shut-off power before making blower speed adjustments. Refer to “Determining Blower Speed” on page 14 and to “Performance Data” on page 20 to determine proper blower RPM.
2. Loosen belt and remove from motor sheave.
3. Loosen set screw on outer side of adjustable motor sheave (see Figure 15.2).
4. To reduce the speed of the blower, turn outer side of motor sheave counterclockwise.
5. To increase the speed of the blower, turn outer side of motor sheave clockwise.
6. Retighten motor sheave set screw, replace belt and retighten motor base. Adjust motor adjusting screw such that there is 3/4″ belt deflection when pressed with 5 pounds of force midway between the blower and motor sheaves (see Figure 15.3). Since the belt tension will decrease dramatically after an initial run-in period, it is necessary to periodically re-check the tension to assure proper belt adjustment.
7. Check to make certain motor sheave and blower sheave are aligned. Re-align if necessary.
8. Re-check blower speed after adjustment.
9. Check motor amps. Do not exceed amps shown on motor nameplate. Slow blower if necessary.
10. Check air temperature rise across unit. Check temperature rise against values shown in Performance Tables on page 20 to assure actual desired air flow is being achieved.
11. If adjustments are required, recheck motor amps after final blower speed adjustment.

START-UP PROCEDURE
IMPORTANT
1. To prevent premature heat exchanger failure, observe heat exchanger tubes. If the bottom of the tubes become red while blower and furnace are in operation, check to be sure the blower has been set to the proper rpm for the application. Refer to page 15 for blower adjustments.
2. Start-up and adjustment procedures must be performed by a qualified service agency.
1. Turn off power to the unit at the disconnect switch. Check that fuses or circuit breakers are in place and sized correctly. Turn all hand gas valves to the “OFF” position.
2. Remove electrical junction box cover. 3. Check that the supply voltage matches the unit supply
voltage listed on the Model Identification Plate. Verify that all wiring is secure and properly protected. Trace circuits to insure that the unit has been wired according to the wiring diagram. If installed at altitudes above 2,000′ and the high altitude kit includes a combustion air proving switch, replace the switch in the unit with the switch provided in the kit. Take care to ensure that the tubing and electrical connections are securely fastened. 4. Check to insure that the venting system is installed correctly and free from obstructions. 5. Check to see that there are no obstructions to the intake and discharge of the unit. 6. For blower units, check the belt tension and sheave alignment. Refer to “Blower Adjustments” for proper belt tension. 7. Check bearings for proper lubrication (if applicable). 8. Check to make sure that all filters are in place and that they are installed properly according to direction of air flow (if applicable). 9. Perform a visual inspection of the unit to make sure no damage has occurred during installation. Lower bottom pan and visually inspect all components in the burner compartment. Check to ensure all fasteners are in place and the burner openings are properly aligned with the heat exchanger tubes and that the gas orifices are centered in the burner inspirator tube opening, as shown in Figure 17.2. 10. Check that all horizontal deflector blades are open a minimum of 30° as measured from vertical. 11. Turn on power to the unit at the disconnect switch. Check to insure that the voltage between electrical junction box terminals T1 and G is 24V. 12. Check the thermostat, ignition control, gas valve, and supply fan blower motor for electrical operation. If these do not function, recheck the wiring diagram. Check to insure that none of the Control Options have tripped. 13. Check the blower wheel for proper direction of rotation when compared to the air flow direction arrow on the blower housing (if applicable). Blower wheel rotation, not air movement, must be checked as some air will be delivered through the unit with the blower wheel running backwards. 14. For blower units, check the blower speed (rpm). Refer to “Blower Adjustments” for modification. 15. Check the motor speed (rpm). 16. Check the motor voltage. On three phase systems, check to make sure all legs are in balance. 17. Check the motor amp draw to make sure it does not exceed the motor nameplate rating. On three phase systems, check all legs to insure system is balanced. 18. Recheck the gas supply pressure at the field installed manual shut-off valve. The minimum inlet pressure should be 6″ W.C. on natural gas and 11″ W.C. on propane gas. The maximum inlet pressure for either gas is 14″ W.C. If inlet pressure exceeds 14″ W.C., a gas pressure regulator must be added upstream of the combination gas valve.

19. Open the field installed manual gas shut-off valve. 20. Open the manual main gas valve on the combination gas
valve. Call for heat with the thermostat and allow the pilot to light for intermittent pilot ignition. If the pilot does not light, purge the pilot line. If air purging is required, disconnect the pilot line at outlet of pilot valve. In no case should line be purged into heat exchanger. Check the pilot flame length (See “Pilot Flame Adjustment”). 21. Once the pilot has been established, check to make sure that the main gas valve opens. Check the manifold gas pressure (see “Main Gas Adjustment”) and flame length (see “Air Shutter Adjustment”) while the supply fan blower is operating. Inspect the condition of the main flame and if necessary, resolve flame appearance problems (see “Burner Flame Adjustment” and Figures 29.1 through 29.4). 22. Check to insure that gas controls sequence properly (see “Control Operating Sequence”). Verify if the unit has any additional control devices and set according to the instructions in the “Control Options”. 23. Once proper operation of the unit has been verified, remove any jumper wires that were required for testing. 24. Replace the electrical junction box cover. 25. If installed at altitudes above 2,000′, affix label included with high altitude kit and fill in all fields with a permanent marker.
Pilot Burner Adjustment
The pilot burner is orificed to burn properly with an inlet pressure of 6-7″ W.C. on natural gas and 11-14″ W.C. on propane gas, but final adjustment must be made after installation. If the pilot flame is too long or large, it is possible that it may cause soot and/or impinge on the heat exchanger, causing failure. If the pilot flame is shorter than shown, it may cause poor ignition and result in the controls not opening the combination gas control. A short flame can be caused by a dirty pilot orifice. Pilot flame condition should be observed periodically to assure trouble-free operation.
To Adjust the Pilot Flame 1. Create a call for heat from the thermostat.
2. Remove the cap from the pilot adjustment screw. For location, see the combination gas control literature supplied with unit.
3. Adjust the pilot length by turning the screw in or out to achieve a soft steady flame 3/4″ to 1″ long and encompassing 3/8″-1/2″ of the tip of the thermocouple or flame sensing rod (see Figure 16.1).
4. Replace the cap from the pilot adjustment screw.

START-UP PROCEDURE
Main Burner Adjustment
The gas pressure regulator (integral to the combination gas control) is adjusted at the factory for average gas conditions. It is important that gas be supplied to the unit heater in accordance with the input rating on the serial plate. Actual input should be checked and necessary adjustments made after the unit heater is installed. Over-firing, a result of too high an input, reduces the life of the appliance and increases maintenance. Under no circumstances should the input exceed that shown on the serial plate.
Measuring the manifold pressure is done at the outlet pressure tap of the gas valve (see Figure 17.1).
To Adjust the Manifold Pressure
1. Move the field installed manual shut-off valve to the “OFF” position.
2. Remove the 1/8″ pipe plug in the pipe tee or gas valve and attach a water manometer of “U” tube type which is at least 12″ high.
3. Move the field installed manual gas shut-off valve to the “ON” position.
4. Create a high fire call for heat from the thermostat. 5. Determine the correct high fire manifold pressure (3.5″ W.C.
for natural gas, 10″ W.C. for propane gas). (Pressures at 0-2,000′ elevation are 3.5″ W.C. for natural gas, 10″ W.C. for propane gas, for elevations above 2,000′ refer to the instructions in “Gas Connections – High Altitude Accessory Kit” on page 12). Adjust the main gas pressure regulator spring to achieve the proper manifold pressure (for location, see the combination gas control literature supplied with unit). 6. After adjustment, move the field installed manual shut-off valve to the “OFF” position and replace the 1/8″ pipe plug. 7. After the plug is in place, move the field installed manual shut-off valve to the “ON” position and recheck pipe plugs for gas leaks with soap solution.

It may also be necessary to adjust the manifold position in addition to adjusting air shutters to obtain proper flame. Follow the instructions under “Natural Gas Flame Control” for adjusting the manifold.

Burner Flame Adjustment
Proper operation provides a soft blue flame with a well-defined inner core. A lack of primary air will reveal soft yellow-tipped flames. Excess primary air produces short, well-defined flames with a tendency to lift off the burner ports. For both natural and propane gas, the flame may be adjusted by sliding the manifold. Also, for units with the air shutters, they can be adjusted to control the burner flame height. The air shutters can be accessed by lowering the bottom pan of the unit heater.
Natural Gas Flame Control Control of burner flames on unit heaters utilizing natural gas is achieved by resetting the manifold position to either increase or decrease primary combustion air. Prior to flame adjustment, operate unit heater for about fifteen minutes. The main burner flame can be viewed after loosening and pushing aside the flame observation disc on the back of the unit.
To increase primary air, loosen the manifold mounting screws and move the manifold away from the burner until the yellowtipped flames disappear (see Figure 17.2). To decrease primary air, move manifold closer to the burner until flames no longer lift from burner ports, but being careful not to cause yellow tipping. Retighten manifold mounting screws after adjustment.
Propane Gas Flame Control An optimum flame will show a slight yellow tip. Prior to flame adjustment, operate heater for at least 15 minutes. Loosen air shutter set screws and move the air shutters away from the manifold to reduce the primary air until the yellow flame tips appear (see Figure 17.3). Then increase the primary air until yellow tips diminish and a clean blue flame with a well-defined inner cone appears.

START-UP PROCEDURE
Control Operating Sequence
All units are supplied with intermittent pilot systems with continuous retry control as standard. For intermittent pilot systems, both the main burner and pilot are turned off 100% when the thermostat is satisfied. For all units, the system will attempt to light the pilot for 70 seconds. If the pilot is not sensed, the ignition control will wait approximately 6 minutes with the combination gas control closed and no spark. After 6 minutes, the cycle will begin again. After 3 cycles, some ignition controllers lockout for approximately 1 hour before the cycle begins again. This will continue indefinitely until the pilot flame is sensed or power is interrupted to the system. Refer to Table 19.1 for control code descriptions. Specific descriptions of the control sequence for different control codes are listed below.
1. The thermostat calls for heat.
2. The power exhauster relay is energized, starting the power exhauster motor. Once the motor has reached full speed, the differential pressure switch closes.
3. The pilot valve opens and the ignitor sparks for 70 seconds in an attempt to light the pilot.
4. Once the pilot is lit, the flame sensor proves the pilot and stops the ignitor from sparking.
5. On single stage units, the main gas valve is opened and the main burner is lit to 100% full fire. On two stage units, the gas valve may open at either 50% or 100%, depending on what the two stage thermostat is calling for.
6. The air mover starts after 30 to 90 seconds to allow the heat exchanger to warm up.
7. The unit continues to operate until the thermostat is satisfied, at which time both the main and pilot valves close 100%.
8. The air mover stops after 30 to 90 seconds to remove residual heat from the heat exchanger.

UNIT AND CONTROL OPTIONS
Figure 19.1 – Factory Mounted Option Location
q

All units include the standard (STD) features. The unit must be reviewed to determine the optional (OPT) features that may have been supplied with the unit.
j Gas Valve
a) Single Stage Gas Valve – (STD) The main gas valve provides the pilot, regulator, main gas, and manual shutoff functions. For additional information, see the supplier literature included with the unit.
b) Two Stage Gas Valve – (OPT) The two stage gas valve provides the pilot, regulator, main gas (100% and 50% fire), and manual shutoff functions. For additional information, see the supplier literature included with the unit.
k Ignition controller – (STD)
The ignition controller is factory installed on the back of the unit heater with the spark igniter and sensor located on the burner. For additional information, refer to “Control Operating Sequence” on page 18 and the supplier literature included with the unit.
l Time Delay Relay – (STD)
The time delay relay is factory installed in electrical junction box and controls propeller/blower motor function. For singlephase units below 2 Hp, the time delay relay controls the motor directly. For single-phase units 2 Hp and greater and all three phase units, the time delay relay controls the motor starter. For additional information, refer to “Control Operating Sequence” on page 18.
m Low Voltage Terminal Board – (STD)
The low voltage terminal board is located in the electrical junction box. The terminal board is labeled to match the electrical wiring diagram provided with the unit. All low voltage field wiring connections should be made to the exposed side of the terminal board (exterior of electrical junction box) to prevent miswiring by modifying the factory wiring, which is inside the electrical junction box.
n Control Step Down Transformer – (STD)
The control step down transformer is located in the electrical junction box. The transformer is used to step down the supply power (115V, 208V, 230V, 460V, 575V) to 24V. This transformer is used to control the gas controls, fan delay relay, field supplied motor starter, etc. All unit heaters are supplied with a 40VA control step down transformer. To determine the control transformer supplied as well as any accessory/field supplied transformers required, reference the supply voltage listed on the serial plate.

o High Limit Switch – (STD)
The automatic reset high limit switch is factory installed on the left side (air blowing at you) of the unit heater. If the limit temperature is exceeded, the gas controls are de-energized until the switch is cooled.
p Pressure Switch (STD)
An automatic reset vent pressure switch is designed to prevent operation of the main burner if there is restricted venting of flue products. This restriction may occur due to an improper vent diameter, long vent runs, unapproved vent terminal, high winds, high negative pressure within space, etc. After the cause of the restriction has been corrected, the pressure switch will reset automatically. See the troubleshooting section for more information.
q Power Exhauster (STD)
All power vented unit heaters are supplied with a round vent pipe connection. Some models may require the use of a vent transition from the power exhauster outlet to the vent pipe (see Table 6.1). The power exhauster may be rotated 180° to allow for various venting directions.
r Blower Motor – (STD on BDP models only)
The blower motor can be provided in a variety of supply voltages and motor horsepowers. Refer to the model nomenclature to determine the motor provided. The blower motor is supplied with an adjustable sheave that can be used to increase/decrease the blower RPM. For instructions on changing the blower RPM, refer to “Blower Adjustments.”

j Outputs shown are for elevations up to 2000′. For elevations over 2000′, output needs to be
reduced 4% for each 1000′ above sea level.
(Does not apply in Canada – see rating plate) k Sheave turns open are approximate.
For proper operation, check blower rpm. l Models not shown use same HP and drive
numbers as cataloged. m Performance is the same; motor sheave
accommodates larger shaft. When ordering
230/460V (1 & 1-1/2 HP) or 575V, specify the
listed 230/460V (1 & 1-1/2 HP) or 575V drive.

MAINTENANCE

WARNING
When servicing or repairing this equipment, use only factoryapproved service replacement parts. A complete replacement parts list may be obtained by contacting the factory. Refer to the rating plate on the appliance for complete appliance model number, serial number, and company address. Any substitution of parts or controls not approved by the factory will be at the owner’s risk.
CAUTION
1. Service or repair of this equipment must be performed by a qualified service agency.
2. Do not attempt to reuse any mechanical or electrical controllers which have been wet. Replace defective controller.
NOTE: To check most of the possible remedies in the troubleshooting guide listed in Table 28.1, refer to the applicable sections of the manual.
General Maintenance The unit and venting system must be checked once a year by a qualified service technician. All installation and service of these units must be performed by a qualified installation and service agency. Before any service, BE SURE TO TURN OFF GAS AT THE MANUAL SHUT-OFF VALVE AHEAD OF THE COMBINATION GAS CONTROL AND TURN OFF ALL ELECTRIC POWER TO THE HEATER.
General Unit When providing annual maintenance for the unit heater, keep the unit free from dust, dirt, grease and foreign matter. Pay particular attention to: 1. The combustion air and exhaust vent piping. 2. The burner ports and pilot burner orifices (avoid the use of
hard, sharp instruments capable of damaging surfaces for cleaning these ports). To check the burner port and pilot burner orifice, see “Burner and Pilot Assembly Removal”. 3. The air shutters and main burner orifices (avoid the use of hard, sharp instruments capable of damaging surfaces for cleaning these orifices). To check the air shutters and main burner orifices, see for “Manifold Assembly Removal.” 4. The heat exchanger. Clean tubes from the bottom with a stiff non-wire brush. 5. The heat exchanger should be checked annually for cracks and discoloration of the tubes. If a crack is detected, the heat exchanger should be replaced before the unit is put back into service. If the tubes are dark gray, airflow across the heat exchanger should be checked to insure that a blockage has not occurred or the blower is operating properly.
Electrical Wiring The electrical wiring should be checked annually for loose connections or deteriorated insulation.

Gas Piping & Controls The gas valves and piping should be checked annually for general cleanliness and tightness.
The gas controls should be checked to ensure that the unit is operating properly.
Propeller Assembly
Check the motor for lubrication if the motor is not permanently lubricated. Inspect the fan for damage and fit on motor shaft. Clean any dust, dirt or foreign matter from the fan blades.
Blower Assembly The blower assembly includes the bearings, drive sheaves and belts. Blower bearings should be checked and lubricated based on the blower manufacturer’s recommendations. Bearings should also be checked for any unusual wear and replaced if needed.
Drive sheaves should be checked at the same time the bearings are inspected. Check to make sure the sheaves are in alignment and are securely fastened to the blower and motor shafts.
Belt tension should be rechecked shortly after the unit has been installed to check for belt stretching. After the initial start-up, monthly checks are recommended.
Manifold Assembly Removal To remove the manifold:
1. Shut off gas and electric supply. 2. Lower bottom pan to expose burner and manifold (see
Figure 17.2). 3. Disconnect pilot tubing and thermocouple lead (or ignition
cable) at the combination gas control (and ignition control). 4. Disconnect control wires for the combination gas control. 5. Disconnect gas manifold at ground union joint. 6. Remove the 2 screws holding the manifold to the heat
exchanger support. 7. Clean the orifices and adjust the air shutters as necessary. 8. Follow steps 2-6 in reverse order to install the manifold
assembly. 9. Turn on the electric and gas supply. 10. Check the ground union joint for leaks with a soap
solution. Tighten if necessary.
Burner and Pilot Assembly Removal To remove the burner:
1. Shut off gas and electric supply. 2. Lower bottom pan to expose burner and manifold (see
Figure 17.2). 3. Disconnect pilot tubing and thermocouple lead (or ignition
cable) at the combination gas control (and ignition control). 4. Remove the 2 burner retaining pins holding the burner in
place. The burner can then be easily lowered from the unit. 5. Examine the burner and pilot assembly for cleanliness
and/or obstructions as necessary (see “General Unit” for cleaning instructions). 6. Replace the burner assembly in reverse order. In replacing the burner, be certain that the slots at the front of the burner are located properly on their shoulder rivets and that the burner retaining pins are put back into their proper locations. 7. Reconnect the ignition cable and pilot gas supply line. 8. Turn on the electric and gas supply.

WARRANTY
This Warranty (the “Warranty”) shall apply to Products (as defined below) sold by Modine Manufacturing Company, a Wisconsin corporation (“Seller”) to you (“Buyer”).
Seller hereby warrants that during the Applicable Warranty Period (as defined below) its Products shall be free from defects in material and factory workmanship under normal use and service, subject to the EXCLUSIONS described below and according to the terms outlined in this Warranty.
If Seller receives written notice of a breach of this Warranty prior to the end of the Applicable Warranty Period (which such notice shall include the model and serial numbers of the Product, as well as the date and a reasonably detailed description of the Product’s alleged failure), Buyer shall with Seller’s prior written approval, return the applicable Product or component thereof to Seller with shipping charges prepaid; if upon examination by Seller such Product or component thereof is disclosed to have been defective, then Seller will, without charge to Buyer, at Seller’s option, either repair the Product, replace defective parts in the Product, or offer an entire replacement unit of the Product; provided that the warranty period for a Product that has been repaired or provided with replacement parts shall not extend beyond the original Applicable Warranty Period, nor shall any replacement parts provided for a Product be under any warranty beyond the original Applicable Warranty Period for the Product; similarly, if Seller provides an entire replacement unit of the Product, the warranty period for the replacement unit is limited to the remainder of the original Applicable Warranty Period. Seller shall have no responsibility for installation, service, field labor, shipping, handling, or other costs or charges, except as expressly provided in this Warranty. Buyer shall have no remedy hereunder for any defective part returned without proper written authorization from Seller, as described above.
For purposes of this Warranty and subject to the exclusions described below, the term “Products” shall mean parts or equipment manufactured by Seller, sold to Buyer pursuant to a purchase contract between Buyer and Seller (most often initiated by a purchase order issued by Buyer and accepted by Seller), and expressly described in such contract. The term “Products” shall not include third-party parts or equipment furnished by Seller, except that, to the extent assignable, Seller will assign to Buyer the benefits (together with all limitations and exclusions) of the thirdparty manufacturer’s warranty for such parts or equipment. This Warranty extends only to the original purchase contract between Buyer and Seller and is nontransferable, except that this Warranty may be assigned to an Authorized End User (as defined below). All replaced parts or equipment shall become Seller’s property. For purposes of this Warranty, the term “Applicable Warranty Period” shall mean the warranty period set forth in the table below for each type or class of Product described on the table; provided that, when the Product is to be used as a component part of equipment manufactured by Buyer, the Applicable Warranty Period shall be limited to one (1) year after the date of shipment from Seller, notwithstanding anything in the table below to the contrary. For purposes of this Warranty, the term “Authorized End User” shall mean any third-party that purchases the Product directly or indirectly from Buyer for the Authorized End User’s own use upon the first installation of the Product and not for resale.

BUYER HEREBY ACKNOWLEDGES THAT ITS REMEDIES FOR BREACH OF THIS WARRANTY, EXCLUSIVE OF ALL OTHER REMEDIES PROVIDED BY LAW, ARE LIMITED AS DESCRIBED ABOVE.
EXCLUSIONS AND LIMITATIONS: This Warranty is subject to the following exclusions and limitations:
The term “Products” shall not include and this Warranty shall not apply to any of the following items: refrigerant gas, belts, filters, fuses and other items consumed or worn out by normal wear and tear.
In addition, this Warranty shall not apply to:
(1) Products or components thereof that are damaged or adversely affected by conditions beyond Seller’s control, including but not limited to polluted or contaminated or foreign matter contained in the air or water utilized for heat exchanger (condenser) cooling or if the failure of the part is caused by improper air or water supply, or improper or incorrect sizing of power supply;
(2) Any Products or components thereof which have been repaired or altered outside the factory of Seller in any way, or otherwise subject to unauthorized repairs or alterations, so as, in the judgment of Seller, to affect the Product’s durability or performance;
(3) Materials or labor of any kind not furnished by Seller, or any charges for any such labor or materials, whether such labor, materials or charges thereon are due to replacement of parts, adjustments, repairs, or any other work done by any party other than Seller;
(4) Labor or other costs incurred for diagnosing, repairing, removing, installing, shipping, servicing, or handling of either defective or replacement parts;
(5) Any Products removed from their original location for reinstallation in another location;
(6) Any Products or components thereof which have been operated, maintained, or serviced contrary to Seller’s written installation, operation, and/or servicing instructions or owner’s manual;
(7) Damages resulting from operation with an inadequate or interrupted supply of air or water;
(8) Any Products or components thereof which have been subjected to misuse, negligence, faulty installation, improper servicing, accident, excessive thermal shock, excessive humidity, physical damage, impact, abrasion, improper operation, or other operating conditions in excess of or contrary to those for which such equipment was designed;
(9) With respect to gas-fired or oil-fired units, any Products or components thereof if the input to the Product exceeds the rated input (as indicated on the Product’s serial plate) by more than five percent (5%);
(10) Any Products or components thereof which, in the judgment of Seller, have been installed in a corrosive atmosphere, marine, or coastal application, subjected to corrosive fluids or gases, or damaged or adversely affected by the effects of the physical or chemical properties of water or steam or other liquids or gases used in the Products or any component thereof;
(11) Damage or failure to start resulting from improper voltage conditions, blown fuses, open circuit breakers, or other

6-580.21

inadequacy or interruption of electrical service or fuel supply; or
(12) Any Products or components thereof from which the serial number has been altered, defaced or removed.
BUYER AGREES THAT THE WARRANTIES AND REMEDIES DESCRIBED HEREIN ARE THE ONLY WARRANTIES AND REMEDIES PROVIDED BY SELLER WITH RESPECT TO THE PRODUCTS AND TO THE MAXIMUM EXTENT PERMITTED UNDER APPLICABLE LAW SHALL BE IN LIEU OF AND EXCLUSIVE OF ALL OTHER WARRANTIES AND REMEDIES WHATSOEVER, EITHER EXPRESS OR IMPLIED, WHETHER ARISING FROM LAW, COURSE OF DEALING, USAGE OF TRADE, OR OTHERWISE, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, EACH OF WHICH SELLER HEREBY EXPRESSLY DISCLAIMS. SELLER NEITHER ASSUMES (NOR HAS AUTHORIZED ANY PERSON TO ASSUME) ANY OTHER WARRANTY OR LIABILITY IN CONNECTION WITH ANY PRODUCTS. REPRESENATATIONS AND CONDITIONS, EXPRESS OR IMPLIED BY STATUTE, TRADE USAGE, OR OTHERWISE, ARE EXCLUDED AND WILL NOT APPLY TO THE PRODUCTS UNDER THIS WARRANTY, EXCEPT FOR WARRANTIES WHICH BY LAW CANNOT BE EXCLUDED

OR LIMITED. Without limiting the foregoing, Seller makes no and specifically disclaims all representations and/or warranties that the Products will detect the presence of, or eliminate, prevent, treat, or mitigate the spread, transmission, or outbreak of any pathogen, disease, virus, or other contagion, including but not limited to COVID 19.
BUYER AGREES THAT IN NO EVENT WILL SELLER BE LIABLE FOR COSTS OF PROCESSING, LOST REVENUES OR PROFITS, INJURY TO GOODWILL, OR ANY OTHER SPECIAL, CONSEQUENTIAL, OR INCIDENTAL DAMAGES OF ANY KIND RESULTING FROM THE PURCHASE OF THE PRODUCTS, OR FROM BUYER’S USE OF ANY PRODUCT, WHETHER ARISING FROM BREACH OF WARRANTY, NONCONFORMITY TO ORDERED SPECIFICATIONS, DELAY IN DELIVERY, OR ANY OTHER LOSS SUSTAINED BY THE BUYER.
OPTIONAL SUPPLEMENTAL WARRANTY
Buyer may purchase from Seller a supplemental warranty with respect to Products which shall extend the Applicable Warranty Period as set forth in the express terms and conditions described in the supplemental warranty agreement. Such supplemental warranty terms may include an additional four (4) years on certain compressors, an additional five (5) years “all parts” warranty, an additional four (4) or nine (9) years on certain heat exchangers, and/ or such additional supplemental warranty terms as Seller chooses to make available to its customers from time to time.
