NOTE
To identify the correct part, you will need to know the
model number, serial number and type of gas when
applicable. This information can be found on the rating
plate sticker, which is located inside the heater on the
outside of the combustion chamber.
6.
Connect a hose between the third part of the tee to
the negative side of the manometer.
7.
Start the heater and record the gas offset pressure
with the heater running and the sealing cap firmly
in place.
8.
If the offset is incorrect, adjust the gas valve until
the correct pressure is obtained, see Table 5.
9.
Remove the tees and replace the hoses to the vent
port at the gas valve and the other hose to the gas
manifold port at the gas valve.
IMPORTANT MAINTENANCE NOTE
We recommend that before each pool session, the
Thermal Regulator Valve (TRV) be inspected for
proper operation and replaced if there are signs of
scaling or corrosion.
The TRV ensures the heater operates at it’s optimal
efficiency and if properly maintained will extend the life
of the heater.
