Vacuum around base of water heater for dust, dirt, and lint on 
a regular basis.

INSTALLED IN SUITABLE AREA: To insure suffi cient ventilation 
and combustion air supply, proper clearances from the water 
heater must be maintained.

 section. Combustible materials such as clothing, 

cleaning materials, or fl ammable liquids, etc. must not be placed 
against or adjacent to the water heater because they could 
catch on fi re.

Anode Rod Inspection

The anode rod is used to protect the tank from corrosion. Most 
hot water tanks are equipped with an anode rod. The submerged 
rod deteriorates to protect the tank. Instead of corroding the tank, 
water ions attack and eat away the anode rod. This does not 
affect the water’s taste or color. The rod must be maintained to 
keep the tank in operating condition.

Anode deterioration depends on water conductivity, not 
necessarily water condition. A corroded or pitted anode rod 
indicates high water conductivity and should be checked and/
or replaced more often than an anode rod that appears to be 
intact. Replacement of a depleted anode rod can extend the 
life of your water heater. Inspection should be conducted by 
calling the Sears Service Center for an authorized contractor. 
At a minimum, the anode(s) should be checked annually after 
the warranty period.

Temperature-Pressure Relief Valve Operation

The temperature-pressure relief valve must be manually operated 
at least once a year.

When checking the temperature-pressure relief valve operation, 
make sure that (1) no one is in front of or around the outlet of 
the temperature-pressure relief valve discharge line, and (2) that 
the water discharge will not cause any property damage, as the 
water may be extremely hot. See Figure 24.

If after manually operating the valve, it fails to completely 
reset and continues to release water, immediately close 
the cold water inlet to the water heater, follow the draining 
instructions, and replace the temperature-pressure relief valve 
with a new one.

If the temperature-pressure relief valve on the appliance weeps or 
discharges periodically, this may be due to thermal expansion.  
You may have a check valve installed in the water line or a 
water meter with a check valve. Consult the Sears Service 
Center for  further information. Do not plug the temperature-
pressure relief valve.

Draining                                                            

The water heater should be drained if being shut down during 
freezing temperatures.  Also periodic draining and cleaning of 
sediment from the tank may be necessary.

1.  Turn the gas control knob to the “OFF” position.
