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 wilt not cause any property damage or bodily injury.
The water may be extremely hot.

DISCHARGE PIPE
FIGURE 16.
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 wilt 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.

• Burn hazard
• Hotwater 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.
• 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.
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.
6. Close the drain valve, refill the tank, and restart the heater as
directed in this manual.
Improper installation and use may result
in property damage.
• Fill tank with water before operation.
FIGURE 17.
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.
