Gas Valve Adjustment
Changes can be made by adjusting the manifold pressure, or changing
orifices (orifice change may not always be required). To adjust the
manifold pressure:
1. Turn off all electrical power to the system.
2. Loosen (Do Not remove) the pressure tap test set screw one turn
with 3/32" hex wrench.
a. The pressure tap adjustment kit (KIT07611) contains a 3/32"
hex wrench, a 5/16" hose and a connector and can be
ordered through Global Parts.
3. Attach a manifold pressure gauge with flexible tubing to the outlet
pressure boss marked "OUT P" on White- Rodgers gas valve
model 36J.
4. Turn on system power and make a call for heating.
5. Adjust gas heat by removing the low (LO) adjustment regulator
cover screw.
a. To increase outlet pressure, turn the regulator adjust screw
clockwise.
b. To decrease outlet pressure, turn the regulator adjust screw
counterclockwise.
c. Adjust regulator until pressure shown on manometer
matches the pressure specified in the table.
The input of no more than nameplate rating and no less than
93% of the nameplate rating, unless the unit is derated for
high altitude.
d. Replace and tighten the regulator cover screw securely.
6. Cycle the valve several times to verify regulator setting.
a. Repeat steps 5-6 if needed.
7. Turn off all electrical power to the system.
8. Remove the manometer and flexible tubing and tighten the
pressure tap screw.
9. Using a leak detection solution or soap suds, check for leaks at the
pressure outlet boss and pressure tap test screw.
10. Turn on system power and check operation of the unit.
