□

  Fresh air openings sized correctly with consideration 

given to the blocking effect of louvers and grilles.

□

  Ductwork is the same cross-sectional area as the 

openings.

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 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 build-up devices installed.

□

  Tempering valve (when applicable) installed per 

manufacturer’s instructions (See Water Temperature 

Regulation section).

□

  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.

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.  

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 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 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 Location Requirements section of this water 

heater manual for specific requirements.

Fresh air 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. 

□

  Fresh air supply free of corrosive elements and 

flammable vapors.
