GENERAL INFORMATION This water heater must be installed in accordance with The Federal Manufactured Home Construction And Safety Standard (H.U.D. Title 24, Part 3280.707d2) or CAN/CSA Z240 MH series, mobile home. In the absence of such a standard, the water heater should be installed in accordance with the Standard For Mobile Homes (ANSI/NFPA NO. 501-B1977).
General Information continued- This water heater has been manufactured for operation at altitudes from sea level to 2000 feet (610m) (unless otherwise specified on the water heater). For use of this appliance at an elevation greater than 2000 feet (610m), contact the dealer or manufacturer listed on the rating plate for information on any necessary modification. Uncorrected operation of this appliance may create a hazard to life and property.
Installation (Locating The Water Heater) continued- Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process chemicals.
Installation (Locating The Water Heater) continued- This water heater MUST be installed indoors out of the wind and weather. This water heater must be located in an area where leakage of the tank, water line connections, or the combination temperature and pressure relief valve will not result in damage to the area adjacent to the water heater or to lower floors of the structure.
Installation continued- Figure 1 Minimum Clearances From Combustible Materials A 0” (0cm) B 0” (0cm) C 3” (7.62cm) D 78” (1.98mm) VENT ---- IMPORTANT The flow of combustion and ventilating air must not be obstructed.
Drain Pan Installation for non-flammable vapor ignition resistant manufactured home water heaters 1. 2. 3. 4. 5. This section is intended for use with non-flammable vapor ignition resistant manufactured home water heaters that will be installed in an application where a drain pan is required. After hole is cut in floor and underside sheathing, and before the water heater is installed, prepare drain pan. Locate and cut a 3-1/2” diameter hole in drain pan at 4-1/2” from center (see Figure 2).
Combustion Air Supply All combustion air must be supplied from outdoors by one of the following installation methods and as illustrated in Figure 5. The flow of combustion and ventilating air must not be obstructed. Adequate air must be supplied for combustion and ventilation. An insufficient supply of air will cause recirculation of combustion products resulting in air contamination that may be hazardous to life.
Combustion air supply continued- 1. After selecting the proper location for the water heater, cut a 4” (10.2cm) diameter hole through the floor and all other layers of flooring and sheathing directly beneath the front center of the water heater. 2. Insert the air intake into the 4” (10.2cm) diameter hole and fasten to the floor with the screws provided. 3. Adjust the air intake so the lower tube extends below the underside sheathing and secure with the screws provided.

Water connections continuedIf this water heater is installed in a closed water supply system, such as the one having a back-flow preventer in the cold water supply, provisions shall be made to control thermal expansion. DO NOT operate this water heater in a closed system without provisions for controlling thermal expansion. Your water supplier or local plumbing inspector should be contacted on how to control this situation.
Water Connections continued- WARNING Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before you use any electrical appliance, which is connected to the hot water system.
Gas Connections The gas supply lines must meet all requirements of the National Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code (Latest Edition). The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0) inch (0.25 kPa) water column above the operating manifold pressure. See the rating plate and gas valve for the manifold pressure and gas type.
Gas Conversion Instructions Unless specifically ordered for operation on natural gas, this water heater is normally equipped for operation on liquefied petroleum (LP) gas but may be converted by following these gas conversion instructions. Caution: Make sure gas to be supplied to this water heater following the conversion matches the gas being converted to. CAUTION All gas conversions must be performed by qualified service personnel only.
Gas Conversion Instructions continued- 7. Replace the burner assembly, reconnect all fittings and check for leaks. Refer to “Gas Connections”. 8. Close and/or replace inner and outer doors. 9. To light pilot, follow the lighting instructions provided on the water heater and in this installation and operation instruction manual. 10. Remove “equipped for” card from cloth bag and attach to gas piping as close to gas control as possible.
Gas Conversion Instructions continued- 7. Replace the burner assembly and reconnect all fittings and check for leaks. Refer to “Gas Connections”. 8. Close and/or replace inner and outer doors. Note: For closed combustion product, make sure screws are tight and seal is made around gas supply tube to burner. 9. To light pilot, follow the lighting instructions provided on the water heater and in this installation and operation instruction manual. 10.

GENERAL OPERATION WARNING Water heaters are heat producing appliances. To avoid damage or injury there shall be no materials stored against the water heater or vent-air intake system, and proper care shall be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.

Thermostat Adjustment Figure 9 The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the ” “ mark on the thermostat dial (approximately 120°F [48.9°C]) as pictured above. Rotate the thermostat dial clockwise to decrease the temperature setting.

General Operation continued- DANGER Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 140 F (60 C). To protect against hot water injury, install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch water lines. A licensed plumbing professional or local plumbing authority should be consulted.
Maintenance Continued- Regular inspection and maintenance of the water heater and vent-air intake system will help to insure safe and reliable operation. 1. Annually check the operation of the thermostat. 2. The flow of combustion and ventilation air MUST NOT be restricted. Clear the combustion air openings of any dirt, dust, or other restrictions. WARNING The ventilation air system may be HOT. 3.
Maintenance Continued- Contact the plumbing professional that installed the water heater or the manufacturer listed on the rating plate for anode replacement information. The use of a water softener may increase the speed of consumption. More frequent inspection of the anode is needed when using softened (or phosphate treated) water. The vent system must be inspected at least once a year to ensure against leakage of exhaust products.
