Locating the New Water Heater (cont’d)

When a drain pan is required, see installation instructions
on pages 9 and 10.
WARNING
Propellants of aerosol sprays and volatile compounds,
(cleaners, chlorine based chemicals, refrigerants, etc.) in
addition to being highly flammable in many cases, will
also change to corrosive hydrochloric acid when exposed
to the combustion products of the water heater. The
results can be hazardous, and also cause product failure.
WARNING
INSTALLATION IN RESIDENTIAL AREAS WHERE
FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE
PRESENT OR STORED (GARAGES, STORAGE AND
UTILITY AREAS, ETC): Flammable liquids (such as
gasoline, solvents, propane (LP) or butane, etc.) or
other substances (such as adhesives, etc.), all of which
emit flammable vapors, may be improperly stored or
used in such areas. The gas water heater pilot light or
main burner can ignite such vapors. The resulting flash-
back and fire can cause death or serious burns to any-
one in the area, as well as property damage.
If installation in such areas is your only option, then
the installation must be accomplished in a way that the
pilot flame and main burner flame are elevated from
the floor at least 18 inches. While this may reduce the
changes of flammable vapors from a floor spill being
ignited, gasoline and other flammable substances
should never be stored or used in the same room or
area containing a gas water heater or other open flame
or spark producing appliance.
Also, the water heater must be located and/or protected
so it is not subject to physical damage by a moving vehicle.
NOTE: Flammable vapors may be drawn by air currents
from other areas of the structure to the appliance.
WARNING
A gas water heater cannot operate properly without
the correct amount of air for combustion. Provide ven-
tilation and combustion air by means of floor openings
as shown in the drawings on pages 9 and 10. Never
obstruct the flow of ventilation air. If you have any
doubts or questions at all, call your gas company.
Failure to provide the proper amount of combustion air
can result in a fire or explosion and can cause DEATH,
SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
If this water heater will be used in beauty shops, bar-
ber shops, cleaning establishments, or self-service
laundries with dry cleaning equipment, it is imperative
that the water heater or water heaters be installed so
that combustion and ventilation air be taken from out-
side these areas. Refer to the “Locating The New
Water Heater” section of this manual and also the lat-
est edition of the National Fuel Gas Code, ANSI
Z223.1, also referred to as NFPA 54 for specifics pro-
vided concerning air required.
WARNING
This water heater must not be installed directly on car-
peting. Carpeting must be protected by a metal or
wood panel beneath the appliance extending beyond
the full width and depth of the appliance by at least 3
inches (76.2mm) in any direction, or if the appliance is
installed in an alcove or closet, the entire floor must be
covered by the panel. Failure to heed this warning may
result in a fire hazard.
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplished in such a man-
ner that if the tank or any connections should leak, the
flow of water will not cause damage to the structure.
When such locations cannot be avoided, a suitable
drain pan should be installed under the water heater.
Drain pans are available at your local hardware store.
Such a drain pan must be not greater than 1 1 ⁄
2
inches
deep, have a minimum length and width of at least 2
inches greater than the water heater dimensions and
must be piped to an adequate drain. The pan must not
restrict combustion air flow. Under no circumstances is
the manufacturer to be held liable for any water dam-
age in connection with this water heater.
WARNING
This water heater shall not be connected to any heating
systems or component(s) previously used with a non-
potable water heating appliance.
WARNING
Toxic chemicals such as used for treatment of boilers or
non-potable water heating appliances shall never be
introduced into a potable water space heating system.
WARNING
When the system requires water at temperatures higher
than required for other uses, the hot water system may
require a means such as a mixing valve to be installed
to temper the water at certain points of use. Some peo-
ple are more likely to be permanently injured by hot
water than others; these include the elderly, children,
the infirm, or the physically/mentally handicapped.
Before immersing yourself or anyone else in hot water,
be sure to check the water temperature. WARNING:
HOTTER WATER INCREASES THE RISK OF SCALD
INJURY. (Also see “Temperature Regulation” section)
Mixing valves are available at plumbing supply or hard-
ware stores. Follow manufacturers instructions for
installation of these valves.
