Installing the water heater.
This water heater must be installed in accordance with these instructions, local codes, utility
company requirements, and/or in the absence of local codes, use the latest edition of the
American National Standard/National Fuel Gas Code. A copy can be purchased from either
the American Gas Association, 400 N. Capitol Street NW, Washington, DC 20001 as ANSI
standard Z223.1 or National Fire Protection Association, 1 Batterymarch Park, Quincy, MA
02269 as booklet NFPA 54.
Location
The water heater should not be
located in an area where leakage
from the tank or connections will
result in damage to the area adjacent
to the heater or to lower floors of the
structure.
When such areas cannot be avoided
it is recommended that a suitable
catch pan, adequately drained, must
be installed under the water heater.
The pan must not restrict air flow to
the combustion air inlet openings
(perforation openings) located around
the lower perimeter of the water heater.
Catch pan kits are available from the store
where the water heater was purchased, or
any water heater distributor.
Make certain the floor underneath the
water heater is strong enough to
sufficiently support the weight of the
water heater once it is filled with water.
A gas fired water heater or any other
appliance should not be installed
in a space where liquids which give off
flammable vapors are to be used or
stored. Such liquids include gasoline, LP
gas (butane or propane), paint or
adhesives and their thinners, solvents or
removers.
When installed in a closet, DO NOT
block or obstruct any of the combustion
air inlet openings located around the
perimeter of the water heater. A
minimum of 1” is required between
these combustion air inlet openings
and any obstruction.
Because of natural air movement in a
room or other enclosed space, flammable
vapors can be carried some distance from
where liquids which give off flammable
vapors are to be used or stored. The open
flame of the water heater’s pilot or main
burner can ignite these vapors and create
a shut down condition of the water
heater which will not allow the water
heater to ignite until examined by a
Qualified Service Technician.
The water heater must be located so it is
not subject to physical damage, for example,
by moving vehicles, area flooding, etc.
If local codes require the use of a stand
kit to raise the water heater 18” above the
floor, please contact the store where the
water heater was purchased, or any water
heater distributor. These kits must
comply with local codes.
● The water heater should be installed as
close as practical to the gas vent or
chimney.
● Long hot water lines should be insulated
to conserve water and energy.
● The water heater and water lines
should be protected from exposure
to freezing temperatures.
● Do not install the water heater in
bathrooms, bedrooms, any occupied
rooms normally kept closed, or in
unprotected outdoor areas.
● Minimum clearance from combustible
construction:
If the clearances stated on the
Instruction/Warning Label, located on
the front of the heater differ, install
the water heater according to the
clearances stated on the label.
● If the water heater is installed in an
alcove or closet, the entire floor must
be covered by a wood or metal panel.
A minimum of 24” clearance from the
front and top should be available for
adequate inspection and servicing.
● The water heater may be installed on
combustible floors, but not directly on
carpeting. If the water heater must be
installed on carpeting, place a metal or
wood panel beneath the water heater,
extending beyond its full width and
depth at least 3” in all directions.
