Draliiing
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.
• Turn the gas control knob to the “OFF” position.
• CLOSE the cold water inlet valve to the water heater.
• OPEN a nearby hot water faucet and leave open to allow for
draining.
• Connect a hose to the drain valve and terminate to an ade­
quate drain.
• OPEN the water heater drain valve to allow for tank
draining.
NOTE: If the water heater is going to be shut down and

[eft open with hose conneaed allowing water to terminate
to an adequate drain.

Temperature-Pressore Relief
Valve Operation
The temperature-pressure relief valve must be mamially operated
at least once a year.
TEMPERATURE-PRESSURE
Failure to install and maintain a new properly listed tempera­
ture-pressure relief valve will release the manufacturer from any
claim which might result from excessive temperature or pressure.
AWARNING
Jf 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 the Sears Service Center for further informa­
tion. Do not plug the temperature-pressure relief v^ve.
AWARNING
When checking the temperature-pressure relief valve opera­
tion, make sure that (I) no one is in front of or around the
outlet of the temperature-pressure relief valve discharge line,
and (2) that the water manually discharged will not cause any
property damage because the water may be extremely hot.
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 widi a new one.

'% 2 " x x Vs" thick washer
