IMPORTANT INFORMATION ABOUT THIS WATER HEATER
This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a flammable vapor ignition incident.
The new technology used in meeting these standards makes this product more sensitive to installation errors. Please review the
following checklist and make any required installation upgrades or changes.

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 base-ring filter located on
the bottom of the water heater will need to be cleaned
periodically. Refer to the “Maintenance of your Water
Heater” section of this manual for information on cleaning
the base-ring filter.
Combustion Air Suppiy and Ventiiation
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 make-up air to enter and exit the
room/area?
□ Are the openings of sufficient size? Remember, if there
are other gas-fired or air-consuming appliances in the
same room, you need more make-up air. Refer to the
“Installation Instructions” and “Combustion Air Supply and
Ventilation” sections for specific requirements.
□ Make sure that fresh air is not taken from areas that contain
negative pressure producing devices such as exhaust fans,
dryers, fireplaces, etc.
□ 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 (HVAC-R) authorized service
provider.
□ Use a fresh air supply that is free of corrosive elements and
flammable vapors.
□ Fresh air openings must be sized correctly with consideration
given to the blocking effect of louvers and grilles.
□ Ductwork must be the same cross-sectional area as the
openings.
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 54)-current
edition.
□ 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.
Water System Piping
□ 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 build-up devices installed.
□ Mixing valve (when applicable) installed per manufacturer’s
instructions (See “Water Temperature Regulation” section).
Gas Suppiy and Piping
□ Gas type is the same as that listed on the water heater rating
plate.
□ Gas line equipped with shut-off valve, union, and drip leg.
□ Use pipe joint compound or teflon tape marked as being
resistant to the action of petroleum [Propane (L.P.)] gases.
□ Adequate pipe size and approved pipe material.
□ An approved noncorrosive leak detection solution used
to check all connections and fittings for possible gas leaks.
Correct any leak found.
