Kenmore HydroSense 153.33443, Owner'S Manual

10

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 
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.

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 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.

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.
