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.
