Anode Rod Inspection
CAUTION
Property Damage Hazard
' Avoid water heater damage.
' Inspection and replacement of anode as needed.
The anode rod is used to protect the tank from corrosion.
Most hot water tanks are equipped with an anode rod. The
submerged rod sacrifices itself 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.
Exposed Pitted Exposed
Anode deterioration depends on the 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 Sears Service Center. 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.
The temperature-pressure relief valve must be manually operated
at least once a year. Caution should be taken to ensure that
(1 ) no one is in front of or around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually
discharged will not cause any property damage or bodily injury.
The water may be extremely hot.
FIGURE 28B.
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.
Failure to install and maintain a new properly listed temperature-
pressure relief valve will release the manufacturer from any claim
which might result from excessive temperature or pressure.
If the temperature-pressure relief valve on the appliance weeps
or discharges periodically, this may be due to thermal expansion.
Your water heater may have a check valve installed in the water
line or a water meter with a check valve. Consult your local
Sears Service Center for further information. Do not plug the
temperature-pressure relief valve.
Draining and Flushing_____________________
ADANGER
Burn hazard
Hot water discharge.
Keep hands clear of drain
valve discharge.
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.
V
A WARNING
Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned “OFF”.
Failure to do this could result in
death, serious bodily injury, or
property damage.
1. Before beginning, turn “OFF” the electric power supply to the
water heater.
2. Open a nearby hot water faucet until the water is no longer hot.
3. Close the cold water inlet valve.
4. Connect a hose to the drain valve and terminate it to an
adequate drain or external to the building.
5. Open the water heater drain valve and allow all of the water
to drain from the tank. Flush the tank with water as needed
to remove sediment.
