A WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that ( I ) no one is in front of or around the outlet of
the temperature-pressure relief valve discharge line, and (2)

damage or bodily injury. 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 with a new one.
Failure to install and maintain a new properly listed tempera-
cure-pressure relief valve will release the manufacturer from any
claim which might result from excessive temperature or pressure.
A WARNING
If the temperature-pressure relief valve on the appliance
weeps or discharges periodically, this may be due to ther
mal 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.
