Prior to installing or replacing this pressure relieve

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 fi 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.
