This water heater must be installed in accordance with
these instructions, local codes, and utility company
requirements.
In the United States where local codes are not available,
use the latest edition of the American National Standard/
National Fuel Gas Code. A copy of the Fuel Gas Code can
be purchased from either the American Gas Association,
400 North Capitol Street Northwest, Washington, DC
20001, as ANSI standard Z223.1, or National Fire
Protection Association, 1 Batterymarch Park, MA 02269
as NFPA 54.
In Canada, use the latest edition of the CAN/CSA B149.1
Natural Gas and Propane Installation Code and the
Canadian Electrical Code, CAN/CSA C22.1, Part 1.
Choosing a Location
WARNING:
Fire Hazard –
Combustible construction refers to adjacent walls and
ceilings and should not be confused with combustible
or flammable products and materials. Combustible
materials, such as clothing, cleaning materials, or
flammable liquids, must not be placed against or next to
the water heater. Fire or explosion could occur causing
death, personal injury, and/or product damage.
A gas-fired water heater should never be installed in a
space or room where liquids with flammable vapors are
used or stored. Such liquids include gasoline, LP gas
(butane or propane), paint, adhesives and their thinners,
solvents, or removers. Flammable vapors carry long
distances from where they are used or stored. The open
flame of the water heater’s main burner can ignite these
vapors causing an explosion or fire.
NOTICE:
Elevating a gas-fired water heater will
reduce but NOT eliminate the possibility of lighting the
vapor of flammable liquids which may be improperly
stored or accidentally spilled.
NOTICE:
This water heater should not be located
in an area where leakage of the heat exchanger or
connections will result in damage to the area adjacent to
it or to lower floors of the structures. When such areas
cannot be avoided, install a suitable catch pan with an
adequate drain under the water heater. This drain pan
must not restrict the combustion airflow.
The following requirements will ensure a safe
installation:
• The water heater must be located in an area where it
won’t sustain damage from moving vehicles, flooding,
etc. If the water heater is installed in a storage garage,
the direct ignition system and main burner should be no
less than 18 in. (45 cm) above the garage floor.
• If the water heater is installed in a repair garage or in
a private garage, the direct ignition system and main
burner should be no less than 4.5 ft. (1400 mm) above
the garage floor.
• The water heater should be installed as close as
possible to the vent termination. This minimizes the
vent length and the number of elbows and joints
required for venting.
• The water heater should be installed with the
proper venting and exhaust materials suitable for
Category III
venting.
