CHECKING GAS PRESSURE
Test all gas joints from the gas meter to the heater valve for leaks using a gas analyzer or soap and water solution after
completing connection.
DO NOT USE AN OPEN FLAME.
Check the gas pressure with the appliance burning and the control set to
HIGH
.
Open control access door on either side of unit to find valve and regulator referred to below.

MILLIVOLT CONTROL
(Figure 23)
The valve regulator controls the burner pressure which
should be checked at the pressure test point.
Turn captured screw counter clockwise two or three
turns and then place tubing to pressure gauge over
test point (Use test point “OUT” closest to control
knob). After taking pressure reading, be sure and turn
captured screw clockwise firmly to re-seal. Do not
over torque. Check for gas leaks.
