Prior to installing or replacing this pressure relieve valve
(PRV), ensure the following steps have been completed.
• Turn off the electrical power to the heater.
• Turn off the main gas supply to the heater.
• If the heater has been operating, ensure you allow
enough time for remaining water in the heat
exchanger to cool down before beginning. It is
recommended that protective gloves be worn during
the entire procedure.
• Make sure the lter pump is off and will remain off
for the duration of the installation procedure.
• If the heater is below the surface level of the water in
the pool or spa, close all shut-off valves between the
heater and the pool.

To ensure the continued proper operation of the pressure
relief valve, the valve should be tested once a year. To
test, lift the lever with the circulation system running to
ensure that water will pass through. When the lever is
down, there should be no leaks from the outlet.
