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. 

Located as close to the gas piping and vent pipe 

system as possible.

   Water heater must be located within 6 feet of 

120VAC outlet.

   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 flame 

arrestor 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 flame-trap. 

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, 

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.

   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.

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.

   Check the vent system for restrictions/obstructions 

and check the vent termination height.  Refer to 

the “Air Supply and Ventilation” section of this 

water heater manual for specific requirements. 

NOTE: 

This water heater utilizes an automatic flue 

damper that remains closed when the water heater 

is not operating. Do not attempt to manually open/

operate the damper. Damage to the flue damper 

may result.

  

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 Supply and Piping

  Gas type is the same as that listed on the water 

heater data plate.

   Gas line equipped with shut-off valve, union, and  

drip leg.

   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.
