Temperature & Pressure Relief Valve
The temperature & pressure relief valve:
Must not be in contact with any electrical part
Must be connected to a proper discharge line which terminates at an
adequate drain.
Must not exceed the working pressure shown on the data plate of the water
heater.
Must be of materials listed for hot water distribution.
Manually operate the temperature and pressure relief valve at least once a year to
make sure it is working properly To prevent water damage the valve must be properly
connected to a discharge line which terminates at an adequate drain.
Standing clear of the outlet (discharged water may be hot), slowly lift and release
the lever handle on the temperature and pressure relief valve to allow the valve to
operate freely and return to its closed position. If the valve fails to completely reset
and continues to release water, immediately shut off the electrical power and the cold
water inlet valve and call a qualifi ed service technician.
