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 inches (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 inches (102 mm) at the front, and 6 inches (153 mm) from
the vent pipe, see Figure 8. Clearance from the top of the
jacket is 12 inches (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.
FIGURE 8.
A gas water heater cannot operate properly without the correct
amount of air for combustion, see Figure 9. Do not install in a
confined area such as a closet, unless you provide air as shown
in the Combustion Air and Ventilation for Appliances Located in
Confined Spaces 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 9.
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.
Insulation Blankets
Insulation blankets available to the general public for external
use on gas water heaters are not necessary with Kenmore
products. The purpose of an insulation blanket is to reduce the
standby heat loss encountered with storage tank heaters. Your
Kenmore water heater meets or exceeds the EPACT standards
with respect to insulation and standby loss requirements, making
an insulation blanket unnecessary.
WARNING
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions (See Figure 1 for
identification of components mentioned below). Failure to follow
these instructions can restrict the air flow required for proper
combustion, potentially resulting in fire, asphyxiation, serious
personal injury or death.
• Do not apply insulation to the top of the water heater, as this
will interfere with safe operation of the draft hood.
• Do not cover the outer door, thermostat or temperature &
pressure relief valve.
• Do not allow insulation to come within 2” (50.8 mm) of the
floor to prevent blockage of combustion air flow to the burner.
