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 filter 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.

Do not overtighten.
The final orientation of the pressure relief valve should be vertically
aligned with the discharge opening facing away from the heater header.
g
Install a discharge pipe from the pressure relief valve
discharge opening to a safe area. This is a precaution to prevent
the possibility of personal injury or property damage in the
event scalding water is discharged from the pressure relief valve.
h
Install the discharge pipe so that there is no trapped or
standing water in the piping. Discharge piping must be facing
down, terminating with a threadless nipple, no more than
6 in (152 mm) and no less than twice the diameter of the
discharge pipe from the floor or drain/receptor..
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.
