AWARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution shouldbe 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) the water manually dischargedwill not causeany
property 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 drain-
ing instructions, and replace the temperature-pressure
relief valve with a new one.

adequate drain or outdoors.

drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
m an adequate drain.

mal expansion.Your water heater may havea check valve
installed in the water line or a water meter with a check
