This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath
the appliance extending beyond the full width and depth of the
appliance by at least 3” (76.2 mm) 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.
Minimum clearances between the water heater and
combustible construction are 0 inch at the sides and rear,
4” (102 mm) at the front, and 6” (153 mm) from the vent pipe.
Clearance from the top of the jacket is 12” (305 mm) on most
models. Note that a lesser dimension may be allowed on
some models, refer to the label attached adjacent to the gas
control valve on the water heater, see Figure 9.
FIGURE 9.
A gas water heater cannot operate properly without the correct
amount of air for combustion. Do not install in a confined area
such as a closet, unless you provide air as shown in the
Locating The New Water Heater section. Never obstruct the
flow of ventilation air. If you have any doubts or questions at all,
call your gas supplier. Failure to provide the proper amount of
combustion air can result in a fire or explosion and cause
death, serious bodily injury, or property damage.
FIGURE 10.
If this water heater will be used in beauty shops, barber 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 outside these areas.
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.
