Housekeeping
Vacuum around base of water heater for dust, dirt, and lint on
a regular basis.
Fire and Explosion Hazard
Do not obstruct combustion air
openings at the bottom of the
water heater.
Do not use or store flammable
vapor products such as gasoline,
solvents or adhesives in the
same room or area near water
heater or other appliance.
At least annually, check the
base-ring filter and flame arrester
for any dust, lint, or debris that
may have accumulated. Clean
as necessary.
Can cause serious injury or death.
AT LEAST ANNUALLY, A VISUAL INSPECTION SHOULD BE
MADE OF THE BASE-RING FILTER AND FLAME ARRESTER.
CLEAN IF LINT ACCUMULATIONS ARE NOTICED.
INSTALLED IN SUITABLE AREA: To ensure sufficient ventilation
and combustion air supply, proper clearances from the water
heater must be maintained. See “Installation Instructions.”
Combustible materials such as clothing, cleaning materials, or
flammable liquids, etc. must not be placed against or adjacent
to the water heater because they could catch on fire.
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.
FIGURE 29B.
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.
Burn hazard
Hot water discharge.
Keep clear of relief valve
discharge outlet.
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 30.
FIGURE 30.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the manual
gas shut-off valve and the cold water inlet valve and call the
Sears Service Center.
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 and Flushing
It is recommended that the tank be drained and flushed
every 6 months to remove sediment which may build up during
