Kenmore 153.331492 - Manual (Page 26)

Housekeeping Temperature-Pressure Relief Valve Operation
Vacuum around base of water heater for dust, dirt, and lint on
a regular basis.
The temperature-pressure relief valve must be manually
operated at least once a year.
ADANGER
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 arrestor
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 ARRESTOR.
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
CAUTION
Property Damage Hazard
■ Avoid water heater damage.
' Inspection and replacement of anode rod required.
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.
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.
TEMPERATURE-PRESSURE
FIGURE 30.
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 and Flushing
ADANGER • Hotwaterdischarge burn hazard.
• Keep clear of relief valve discharge
unit.
• Temperature limiting valves are
available.
• Read instruction manual for safe
temperature setting.
It is recommended that the tank be drained and flushed
every 6 months to remove sediment which may build up during
operation. The water heater should be drained if being shut
