SECTION IV: INSTALLATION INSTRUCTIONS
CAUTION
If building cold water supply has a back-flow preventer, check valve or water meter with check valve,
provisions for thermal expansion of water in the hot water system must be provided.
WARNING
This water heater must be located in an area where leakage of the heat exchanger coil, water line
connections, or the 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. The drain pan depth must be suitable for draining and collecting water,
and have a minimum length and width of at least four (4) inches (10.2 cm) measured from the jacket of
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 ¾ inch (1.9 cm) in
diameter and pitched for proper drainage.
WARNING
Pressure relief valve discharge piping must be piped near floor to eliminate potential of severe burns. Do
not pipe in any area where freezing could occur. Do not install any shut-off valves, plugs or caps to the
temperature and pressure relief valve or piping.
DANGER
Temperature setting should not exceed safe temperature at fixtures. See water temperature control
warning in the “Temperature Adjustment” section of this Installation and Operating Instruction Manual. If
higher preheat temperatures are necessary to obtain adequate booster output, add an ASSE approved
mixing valve for hot water supplied to fixtures.
WARNING
INSTALLATION OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A
LICENSED PLUMBER. PLUMBING, AIR SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL
WORK ARE REQUIRED.
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 telephone in another building.
• Gas detectors are available. Contact your gas supplier or plumbing professional for more
information.
Liquefied petroleum gases/propane gas is 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 telephone in another building. Follow the gas
supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!
