Kenmore Power Miser 9 Gas Water Heater 153.33096 - Manual (Page 10)

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 directly from outdoors (direct vent).
Propellants of aerosol sprays and volatile compounds, (cleaners,
chlorine based chemicals, refrigerants, etc.) in addition to being
highly fl ammable 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 National Appliance
Energy Conservation Act standards with respect to insulation
and standby loss requirements, making an insulation blanket
unnecessary.
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 8 inches (203
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.
FIGURE 9.
A gas water heater cannot operate properly without the correct
amount of air for combustion, see Figure 9. Do not install in a
confi ned area such as a closet, unless you provide air as shown
in the Locating The New Water Heater section. Never obstruct
the fl ow 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 fi re or explosion and cause death,
serious bodily injury, or property damage.
WARNING
Should you choose to apply an insulation blanket to this
heater, you should follow these instructions (See Figure 1 for
identifi cation of components mentioned below). Failure to follow
these instructions can restrict the air fl ow required for proper
combustion, potentially resulting in fi re, 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 fl oor
to prevent blockage of combustion air fl ow to the burner.
• Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
