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. The anode rod should
be checked after a maximum of three years of use, then annually
until the condition of the anode rod dictates the replacement of it.
NOTE: Artifi cially softened water requires the anode rod to be
inspected annually.

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 33.
FIGURE 33.
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

It is recommended that the tank be drained and fl ushed every 6
months to remove sediment which may build up during operation.
The water heater should be drained if being shut down during
freezing temperatures. To drain the tank, perform the following
steps:
1. Turn off the gas to the water heater at the manual gas
shut-off valve.
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.
6. Close the drain valve, refi ll the tank, and restart the heater
as directed in this manual.
If the water heater is going to be shut down for an extended
period, the drain valve should be left open.
IMPORTANT: Condensation may occur when refi lling the tank
and should not be confused with a tank leak.
Follow the lighting instructions in the Lighting section to restart
the water heater.
