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
