Standards Compliance
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 CSA
B149.1 Natural Gas and Propane Installation
Code and the Canadian Electrical Code,
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 damaged from moving
vehicles, flooding, etc. If the water heater is
installed in a garage, the direct ignition system
and main burner should be no less than 18 in.
(45 cm) above the garage floor.
• The water heater should be installed as close as
possible to the vent exhaust and air intake. 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.
