Installation Requirements

The water heater must be 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)-latest edition. Canadian installations must be

performed in accordance with CAN/CSA-B149.1.

Note: In the State of California, the water heater must

be braced, anchored, or strapped to avoid moving dur-

ing an earthquake. Contact local utilities for code

requirements in your area or call 1-800-456-9805 and

request instructions.

Site Location

Select a location near the center of the water

piping system. The water heater must be

installed indoors and in a vertical position on a

level surface. DO NOT install in bathrooms,

bedrooms, or any occupied room normally kept

closed.

Locate the water heater as close to the gas

vent as practical. Consider the vent system

piping and combustion air supply requirements

when selecting the water heater location. The

venting system must be able to run from the

water heater to termination with minimal length

and elbows.

Locate the water heater near the existing gas

piping. If installing a new gas line, locate the

water heater to minimize the pipe length and

elbows.

The water heater should be located in an area

not subject to freezing temperatures. Water

heaters located in unconditioned spaces (i.e.,

attics, basements, etc.) may require insulation

of the water piping and drain piping to protect

against freezing. The drain and controls must

be easily accessible for operation and service.

Maintain proper clearances as specified on the

data plate.

The operation of air-moving devices such as

exhaust fans, ventilation systems, clothes

dryers, fire-places, etc., can affect the proper

operation of the water heater. Note: Special

attention must be given to the location of these

devices and the conditions they may create.

Flow reversal of flue gases may cause an

increase of carbon monoxide inside of the

dwelling.

Important: Air for combustion and ventilation must not

come from a corrosive atmosphere. Any failure due to

corrosive elements in the atmosphere is excluded from

warranty coverage.

The following types of installation (but not limited to the

following) will require outdoor air for combustion due to

chemical exposure, and may reduce but not eliminate

the presence of corrosive chemicals in the air:

Beauty shops

Photo processing labs

Buildings with indoor pools

Water heaters installed in laundry, hobby or

craft rooms

Water heaters installed near chemical storage

areas
