WARNING
This water heater has been factory equipped to operate with the type gas indicated in the “EQUIPPED FOR” area of the rat­ing plate located near the gas control valve. The indicated gas may be either Natural or Propane (L.P.). By following the con­version instructions in this manual or the instructions near the gas control valve, the water heater must be converted if it is to be used with the opposite gas. DO NOT USE THIS WATER HEATER WITH ANY GAS OTHER THAN THE ONE LISTED ON THE MODEL RATING PLATE. Failure to use the correct gas can cause problems which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your gas supplier or gas company.
WARNING
A fire can start if combustible materials such as clothing, cleaning materials, or flammable liquids are placed against or next to the water heater.
WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE, AND UTILITY AREAS, ETC): Flammable liquids (such as gasoline, solvents, propane (LP) or butane, etc.), all of which emit flammable vapors, may be improperly stored or used in such areas. The gas water heater pilot light or main burner can ignite such vapors. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage. If installation in such areas is your only option, then the installa­tion must be accomplished in a way that the pilot flame and main burner flame are elevated from the floor at least 18 inches. While this may reduce the chances of flammable vapors from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.
WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to pro­duce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/men­tally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, some type of tempering device, such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hard­ware stores. Follow manufacturers instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.
WARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]: Propane (L.P.) gas is heavier than air. Should there be a leak in the system, the gas will settle near the ground. Basements, crawl spaces, skirted areas under manufactured homes (even when ventilated), closets and areas below ground level will serve as pockets for the accumulation of this gas. Before attempting to light or relight the water heater’s pilot or turning on a nearby electrical light switch, be absolutely sure there is no accumulated gas in the area. Search for odor of gas by sniffing at ground level in the vicinity of the appli­ance. If odor is detected, follow steps indicated at “For Your Safety” on the cover page of this manual then leave the premises.
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manual for assis­tance or call the manufacturer whose name appears on the rating plate for further information.
WARNING
At the time of manufacture this water heater was provided with a combination temperature-pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, and the current edition of ANSI Z21.22 and the code requirements of ASME. If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized testing labo­ratory that maintains periodic inspection of production of listed equipment or materials. The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 lbs. p.s.i.) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr. rate.) Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI Z21.22 and ASME, may require a valve model different from the one furnished with the water heater. Compliance with such local requirements must be satisfied by the installer or end user of the water heater with a locally pre­scribed temperature-pressure relief valve installed in the desig­nated opening in the water heater in place of the factory fur­nished valve. For safe operation of the water heater, the relief valve must not be removed from it’s designated opening or plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet, or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to dis­charge drain unless a 6air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circum­stances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause prop­erty damage. The Discharge Pipe: —Must not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions. —Must not be plugged or blocked. —Must be of material listed for hot water distribution. —Must be installed so as to allow complete drainage of both
the temperature-pressure relief valve, and the discharge pipe. —Must terminate at an adequate drain. —Must not have any valve between the relief valve and tank.

WARNING
This water heater must not be installed directly on carpeting. Carpeting must be protected by a metal or wood panel beneath the appliance extending beyond the full width and depth of the appliance by at least 3 inches (76.2mm) in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be covered by the panel. Failure to heed this warning may result in a fire hazard.
WARNING
A gas water heater cannot operate properly without the correct amount of air for combustion. Do not install in a confined area such as a closet, unless you provide air as shown in the “Locating The New Water Heater” section. Never obstruct the flow of ven­tilation air. If you have any doubts or questions at all, call your gas company. Failure to provide the proper amount of combus­tion air can result in a fire or explosion and can cause death, seri­ous bodily injury, or property damage.
WARNING
If this water heater will be used in beauty shops, barber shops, cleaning establishments, or self-service laundries with dry clean­ing equipment, it is imperative that the water heater or water heaters be installed so that combustion and ventilation air be taken from outside these areas. Refer to the “Locating The New Water Heater” section of this manual and also the current edition of the National Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for specifics provided concerning air required.
WARNING
VENT DAMPERS - Any vent damper, whether it is operated ther­mally or otherwise must be removed if its use inhibits proper drafting of the water heater. Thermally Operated Vent Dampers: Gas-fired water heaters hav­ing thermal efficiency in excess of 80% may produce a relatively low flue gas temperature. Such temperatures may not be high enough to properly open thermally operated vent dampers. This would cause spillage of flue gases and may cause carbon monox­ide poisoning. Vent dampers must bear evidence of certification as complying with the current edition of American National Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically and mechanically actuated vent dampers). Before installation of any vent damper, consult the gas utility for further information.
WARNING
1. The appliance and its individual shutoff valve must be discon-
nected from the gas supply piping system during any pressure
testing of the gas system at test pressures in excess of 1⁄
2 pound
per square inch (3.5kPa).
2. The appliance must be isolated from the gas supply piping sys-
tem by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pres-
sures equal or less than
1
2 pound per square inch (3.5kPa).
WARNING
Soot build-up indicates a problem that requires correction before further use. Turn “off” gas to water heater and leave “off” until repairs are made, because failure to correct the cause of the soot­ing can result in a fire or explosion causing death, serious bodily injury, or property damage.
WARNING
The water heater with draft hood installed must be properly vent­ed to a roof jack which terminates outdoors. Never operate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper operation, explosion or asphyxiation.
WARNING
Obstructed or deteriorated vent systems may present a serious health risk or asphyxiation.
WARNING
Chemical vapor corrosion of the flue and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chlo­ride, waxes, bleach, and process chemicals are typical compounds which are potentially corrosive.
WARNING
Minimum clearances between the water heater and combustible and noncombustible construction are 1at the sides and rear, 4 at the front, and 6from the vent pipe. Clearance from the top of the draft hood is 12. Refer to the label on the water heater locat­ed adjacent to the gas control valve for all clearances.
WARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (general­ly two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before any electrical appli­ances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.
WARNING
INSULATING JACKETS: When installing an external water heater insulation jacket on a gas water heater: a. DO NOT cover the temperature-pressure relief valve. b. DO NOT put insulation over any part of the top of the gas water
heater.
c. DO NOT put insulation over the gas control valve or gas control
valve/burner cover, or any access areas to the burner.
d. DO NOT let insulation around the gas water heater to get with-
in 8 inches of the floor (air must get to the burner).
e. DO NOT cover or remove operating instructions, and safety
related warning labels and materials affixed to the water heater. Failure to heed this will result in the possibility of a fire or explosion.
WARNING
Flood damage to a water heater may not be readily visible or immediately detectible. However, over a period of time a flood­ed water heater will create dangerous conditions which can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAM­AGE. Call a qualified service technician or contractor to replace a flooded water heater. Do not attempt to repair the unit! It must be replaced!
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. When such locations cannot be avoid­ed, a suitable drain pan should be installed under the water heater. Drain pans are available at your local hardware store. Such a drain pan must be not greater than 11⁄2 inches deep, have a minimum length and width of at least 2 inches greater than the water heater dimensions and must be piped to an adequate drain. The pan must not restrict combustion air flow.

WARNING
When the system requires water at temperatures higher than required for other uses, the hot water system may require a means such as a mixing valve to be installed to temper the water at certain points of use. Some peo­ple are more likely to be permanently injured by hot water than others; these include the elderly, children, the infirm, or the physically/mentally handicapped. Before immersing yourself or anyone else in hot water, be sure to check the water temperature. WARNING: HOTTER WATER INCREASES THE RISK OF SCALD INJURY. (Also see “Temperature Regulation” section) Mixing valves are available at plumbing supply or hard­ware stores. Follow manufacturers instructions for installation of these valves.
WARNING
This water heater shall not be connected to any heating systems or component(s) previously used with a non­potable water heating appliance. If this water heater is also used for space heating applica­tions, all piping and components connected to the water heater shall be suitable for use with potable water.
WARNING
Toxic chemicals such as used for treatment of boilers or non-potable water heating appliances shall never be introduced into a potable water space heating system.
Facts to Consider About the Location
This manufactured home gas-fired water heater is for use in a manufactured home.You should carefully choose an indoor location for the new water heater, because the placement is a very important consideration for the safety of the occupants in the building and for the most economi­cal use of the appliance. This water heater is for use only
in manufactured homes and is not intended for outdoor installation.
The installation of this water heater must be within an enclosure so as to separate the appliance combustion sys­tem and venting system from the interior atmosphere of the manufactured home. There shall not be any door, removable access panel, or other opening into the enclo­sure from the inside of the manufactured home.
Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed.
1. An enclosure with an exterior access door incorporat-
ing a single opening positioned a maximum of 6 inches above the lower edge of the access door and which may incorporate either 1/4 inch wire mesh or louvers. When 1/4 inch wire mesh is used, the size of the open­ing must be a minimum of 20 square inches. When the louvers are used, the area must be a minimum of 20 square inches. (See figure 1, page 6)
2. An optional enclosure incorporating a solid exterior
access door, when a 5 inch or 8 inch diameter, or 20 square inch minimum equivalent free air opening is located in the floor of the enclosure. The opening must be covered by a 1/4 inch wire mesh. (See figure 2, page 6)
Install water heater into closet so as to have 1 inch mini­mum clearance at sides and back. Clearance of 4 inches is needed to front to accommodate the gas control valve. (See Figure 3) Be sure to allow adequate clearance for ser­vicing the water heater and for access to the piping and temperature-pressure relief valve.
The water heater should be secured to the floor and to the wall of the enclosure with the mounting brackets provided. For bracket location refer to “Securing Water Heater to Floor and Wall” in the “Installing the New Water Heater” section.
When a manufactured home is skirted, an air intake open­ing with a minimum free area of 32 square inches must be provided in the skirt. Other gas fired appliances in the home will require additional free air openings; consult these manufacturers for correct sizing.
If the opening is covered by louvers or screen, the total free area must be 32 square inches.
Locating the New Water Heater
When a drain pan is required, an exterior door with lou­vered openings must be used as shown in figure 1, page 6.

WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE AND UTILITY AREAS, ETC): Flammable liquids (such as gasoline, solvents, propane (LP) or butane, etc.) or other substances (such as adhesives, etc.), all of which emit flammable vapors, may be improperly stored or used in such areas. The gas water heater pilot light or main burner can ignite such vapors. The resulting flash­back and fire can cause death or serious burns to anyone in the area, as well as property damage. If installation in such areas is your only option, then the installation must be accomplished in a way that the pilot flame and main burner flame are elevated from the floor at least 18 inches. While this may reduce the chances of flammable vapors from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are avail­able at your local hardware store. Such a drain pan must be not greater than 11⁄2 inches deep, have a minimum length and width of at least 2 inches greater than the water heater dimensions and must be piped to an adequate drain. The pan must not restrict combustion air flow.
WARNING
Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable in many cases, will also change to corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure.
