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 at bottom front of unit to find valve and
regulator referred to below.
MANUAL CONTROL
(Figure 29)
The pressure regulator is preset and locked to discour-
age tampering. If the pressure is not as specified, re-
place the regulator with the correct part from the parts
list in this manual.
Remove 1/8" NPT plug, located on side of regulator
body. Install fitting and tubing to pressure gauge. Af-
ter taking pressure reading, reinstall test plug. Check
for gas leaks.
THERMOSTAT CONTROL
(Figure 30)
Turn captured screw counter clockwise two or three
turns and then place tubing to pressure gauge over test
point (Use test point closest to control knob). After tak-
ing pressure reading, be sure and turn captured screw
clockwise firmly to reseal. Do not over torque. Check
for gas leaks.
MILLIVOLT CONTROL
(Figure 31)
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 “A” closest to gas inlet). After
taking pressure reading, be sure and turn captured screw
clockwise firmly to reseal. Do not over torque. Check
for gas leaks.
