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).
The warranty for this water heater is in effect only when the water heater is installed, adjusted, and operated in accordance with these Installation and Operating Instructions. The manufacturer will not be liable for any damage resulting from alteration and/or failure to comply with these instructions.
This water heater is of the closed combustion type (direct venting) where all the combustion air is supplied from the outdoors through the air intake and all combusted gas products are vented directly to the outside by means of the roof jack. No draft diverter (vent hood) is required for this water heater.
Underwriters Laboratories, Inc. has tested a representative sample of this water heater design for its safety of operation. The UL listing of this water heater includes the field installation of the following components: roof jack, air intake tube, and heater tie down materials. These components for field installation may have been shipped with this heater and must be installed according to these instructions (see figure 1). No other components are approved for use with this water heater.
This water heater has been designed and certified for the purpose of heating potable water. The installation and use of this water heater for any purpose other than the heating of potable water may cause damage to the water heater, create a hazardous condition, and nullify the warranty.
CAUTION
Incorrect operation of this appliance may create a hazard to life and property and will nullify the warranty.
Do not use this appliance if any part has been submerged in water. You should contact the plumbing professional who installed the water heater to inspect the appliance and to replace any part of the control system including the combination gas control which has been submerged in water.
IMPORTANT
Before proceeding, please inspect the water heater and components for possible damage. DO NOT install any damaged components. If damage is evident then please contact the supplier where the water heater was purchased or the manufacturer listed on the rating plate for replacement parts.

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.
DANGER
Do not store or use gasoline or other flammable, combustible, or corrosive vapors and liquids in the vicinity of this or any other appliance.
Make sure to check the rating plate and combination gas control on the water heater to be certain that the type of gas being supplied corresponds with the marking on the rating plate and combination gas control.
A sacrificial anode is used to extend tank life. The removal of this anode, for any reason, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and the impurities in the water. If this should happen, an alternative anode may be purchased from the supplier that installed this water heater. This will minimize the odor while protecting the tank. Additionally, the water heater should be flushed with appropriate dissolvers to eliminate any bacteria.
INSTALLATION
Locating the Water Heater
This water heater MUST NOT be installed in any location where gasoline or flammable vapors are likely to be present, unless the installation is such to eliminate the probable ignition of gasoline or flammable vapors.
The location of this water heater is of the utmost importance. Before installing this water heater, read the Installation section of these instructions. DO NOT locate the water heater where water lines could be subjected to freezing temperatures. Make sure the cold water pipes are not located directly above the gas control so that condensate during humid weather does not drip on the controls.
WARNING
Water heaters are heat producing appliances. To avoid damage or injury there must be no materials stored against the water heater or vent-air intake system and proper care must be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake components. UNDER NO CIRCUMSTANCES MAY FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER HEATER OR VENTAIR INTAKE SYSTEM.
5
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. These materials are corrosive at very low concentration levels with little or no odor to reveal their presence. NOTE: DAMAGE TO THE WATER HEATER CAUSED
BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY THE WARRANTY. DO NOT OPERATE THE WATER HEATER IF EXPOSURE HAS OR WILL OCCUR. DO NOT STORE ANY POTENTIALLY CORROSIVE COMPOUNDS IN THE VICINITY OF THE WATER HEATER.
For exact venting specifications, please consult the Venting section of these Installation and Operating Instructions. It is recommended that a minimum clearance of 4 inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the combination temperature and pressure relief valve.
WARNING
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING:
•Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in detection of the gas.
•Most people recognize this odor as a “sulfur” or “rotten egg” smell.
•Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or “fade”, and not be as readily detectable.
•If you have a diminished sense of smell, or are in any way unsure of the presence of gas, immediately contact your gas supplier from a neighbor’s telephone.
•Gas detectors are available. Contact your gas supplier or plumbing professional for more information.
WARNING
Liquefied petroleum gases/propane gases are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.
IF YOU SMELL GAS:
•Do not try to light any appliance.
•Do not touch any electric switch; do not use any telephone in your building.
•Immediately call your gas supplier from a neighbor’s telephone. Follow the gas supplier’s instructions.
•If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

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. When such locations cannot be avoided, a suitable drain pan must be installed under the water heater (Refer to drain pan installation section for more information.). The drain pan must have a minimum length and width of at least 4 in. (10.2 cm) greater than the diameter of the water heater and must not restrict proper combustion air flow to the water heater. The drain pan, as described above, can be purchased from your plumbing professional. The drain pan must be piped to an adequate drain. The piping must be at least 3/4 inch (1.9 cm) in diameter and pitched for proper drainage.
To comply with NSF requirements this water heater is to be:
a)Sealed to the floor with sealant, in a smooth and easily cleanable way, or
b)Installed with an optional leg kit that includes legs and/or extensions that provide a minimum clearance of 6” beneath the water heater.
Note: For California installation this water heater must be braced, anchored, or strapped to avoid falling or moving during an earthquake. See instructions for correct installation procedures. Instructions may be obtained from the DSA Headquarters Office, 1102 Q Street, Suite 5100, Sacramento, CA 95811.
