Housekeeping

Vacuum around base of water heater for dust, dirt, and lint on
a regular basis.
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.
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.
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.
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.
See "Installation Instructions."
The anode rod should be inspected after a maximum of three
years and annually thereafter until the condition of the anode
rod dictates its replacement. NOTE: Artificially softened water
requires the anode rod to be inspected annually.
Anode Rod Depletion

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 27.
