Temperature-Pressure Relief Valve Operation; Draining And Flushing - Kenmore 153.316050 Use & Care Manual

Temperature-Pressure Relief
Valve Operation
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 14.
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

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.
1. Before beginning turn "OFF" the electric power supply to the
water heater.
HAZARD OF ELECTRICAL SHOCK! 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.
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 to an
adequate drain or external to the building.
5. OPEN the water heater drain valve to 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, refill the tank, and restart the heater as
directed in this manual.
NOTE: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
7. Turn "ON" power to the water heater.
Never use this water heater unless it is completely full of water.
To prevent damage to the tank and heating element, the tank
must be filled with water. Water must flow from the hot water
faucet before turning "ON" power.
