Installation Checklist
Water Heater Location
Water heater location is important and can affect system performance. Please check the following:
□Installation area free of corrosive elements and flammable materials.
□Centrally located with the water piping system (For new installations). Located as close to the gas piping and vent pipe system as possible.
□Located indoors and in a vertical position. Protected from freezing temperatures.
□Proper clearances from combustible surfaces maintained and not installed directly on a carpeted floor.
□Provisions made to protect the area from water damage. Metal drain pan installed and piped to an adequate drain.
□Sufficient room to service the water heater. See Clearances and Accessibility section of this manual.
□Water heater not located near an air moving device.
□Is the installed environment dirty (excessive amounts of lint, dirt, dust, etc.)? If so, the
Combustion Air Supply and Ventilation
Check for sufficient combustion air supply. Insufficient air for the combustion of gas will result in the flame becoming “lazy”, thereby allowing heat to build up in the combustion chamber. This excessive heat will cause a thermal switch on the door assembly to trip. Is the water heater installed in a closet or other small, enclosed space? If so:
□Are there openings for
□Are the openings of sufficient size? Remember, if there are other
□Make sure that fresh air is not taken from areas that contain negative pressure producing devices such as exhaust fans, dryers, fireplaces, etc.
□Fresh air openings must be sized correctly with consideration given to the blocking effect of louvers and grilles.
□Ductwork must be the same
Vent Pipe System
Check for proper drafting at the water heater draft hood. Refer to the “Checking the Draft” section of this manual for the test procedure. If the procedure shows insufficient draft is present, please check the following:
□Draft hood properly installed.
□Vent connectors securely fastened with screws and supported properly to maintain six inch clearance.
□Vent connector made of approved material and sized correctly.
□Vent pipe system installed according to all local and state codes or, in the absence of local and state codes, the “National Fuel Gas Code”, ANSI Z223.1(NFPA
□Flue baffle properly positioned in the flue tube.
□Check the vent system for restrictions/obstructions and check the vent termination height. Refer to the “Combustion Air Supply and Ventilation” section of this water heater manual for specific requirements.
□Recheck for sufficient combustion air supply.
□Temperature and pressure relief valve properly installed with a discharge line run to an open drain and protected from freezing.
□All piping properly installed and free of leaks.
□Heater completely filled with water.
□Closed system pressure
□Tempering valve (when applicable) installed per manufacturer’s instructions (See “Water Temperature
□Is there a furnace/air handler in the same room space as the water heater? If so, has a return air duct system been attached that exits the room? If so, check for leaks on the air duct system. If no air duct system is present, correct immediately by contacting a local Heating, Ventilation, Air- Conditioning & Refrigeration
□Use a fresh air supply that is free of corrosive elements and flammable vapors.
