This water heater must be installed in accordance with local codes. In the absence of local codes, it must be installed in compliance with the National Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Ins tallation Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code (Latest Edition). 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 not design certified for installation in a mobile home. Such an installation may create a hazardous condition and will nullify the warranty.
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.

General Information continued -
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.
This water heater has been manufactured for operation at altitudes from sea level to 2000 feet (610m) (unless otherwise specified on the water heater rating plate). 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.
Make sure that you 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
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 components.
UNDER NO CIRCUMSTANCES SHALL 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 VENT-AIR INTAKE SYSTEM.
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.
Water heaters in residential garages must be installed and located, or protected, to avoid physical damage. For other installations refer to local codes. In the absence of local codes, the water heater must be installed in compliance with the National Fuel Gas Code, (ANSI Z223.1­Latest 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 location of this water heater is of the utmost importance. Before installing this water heater read the Installation section of these instructions. After reading these Installation and Operating Instructions, select a location for the water heater where the fl oor is level and is easily accessible to gas and water supply lines. 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.

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.
WARNING
Liquefied petroleum gases/propane gas 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!

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.
Proper venting practices must be considered when selecting a location for this water heater. For exact venting specifications, please consult the Venting section of these Installation and Operating Instructions.
The appliance should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the appliance or to lower floors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not restrict combustion air flow.
It is recommended that a minimum clearance of four (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.
