Gas Inlet Pressure Check
Gas inlet pressure must be checked and adjusted in accor-
dance to the type of fuel being consumed.
With Power And Gas Off:
NOTE : Use adapter kit #0151K00000S to measure gas pres-
sure on White-Rodgers 36G54 gas valves.
1. Back inlet pressure test screw (inlet pressure boss) out
one turn (counterclockwise, not more than one turn). Al -
ternately, inlet gas pressure may be measured by remov-
ing the cap from the drip leg and installing a predrilled cap
with a hose barb fitting.
2. Connect a water manometer or adequate gauge to the
inlet pressure tap of the gas valve (or hose barb fitting on
predrilled cap).
With Power And Gas On:
3. Put unit into heating cycle and turn on all other gas con-
suming appliances.
Natural Min. 5.0" W.C., Max. 10.0" W.C.
Propane Min. 11.0" W.C., Max. 13.0" W.C.
INLET GAS PRESSURE
Inlet Gas Pressure Must be within the Minimum and Maximum Value
Shown in Table Above.
NOTE: Inlet Gas Pressure must be within the minimum and
not exceed the maximum value shown. If operating pressures
differ from above, make necessary pressure regulator adjust -
ments, check piping size, etc., and/or consult with local utility.
4. Turn off all electrical power and gas supply to the system.
5. Remove manometer hose from the outlet pressure
boss (or remove hose from hose barb).
6. Turn inlet pressure test screw in to seal pressure port
(clockwise, 7 in-lb minimum). Alternately, remove pre -
drilled cap from drip leg. Reinstall original cap, sealing
with pipe thread compound.
7. Turn on electrical power and gas supply to the system.
8. Turn on system power and energize valve.
9. Using a leak detection solution or soap suds, check for
leaks at the pressure boss screw (or drip leg cap). Bub -
bles forming indicate a leak. SHUT OFF GAS AND FIX
ALL LEAKS IMMEDIATELY.

Measuring Inlet Gas Pressure Alternate Method
Manifold Pressure Check
1. Turn OFF gas to furnace at the manual gas shutoff
valve external to the furnace.
2. Turn off all electrical power to the system.
3. Back outlet pressure test screw (outlet pressure boss)
out one turn (counterclockwise, not more than one turn).
4. Attach a hose and manometer to the outlet pressure
boss of the valve.
5. Turn ON the gas supply.
6. Turn on power and energize main (M) solenoid. Do not
energize the HI solenoid.
7. Measure gas manifold pressure with burners firing. Ad -
just manifold pressure using the Manifold Gas Pres-
sure table.
8. Remove regulator cover screw from the low (LO) outlet
pressure regulator adjust tower and turn screw clock-
wise to increase pressure, or counterclockwise to de-
crease pressure.
9. Energize main (M) solenoid as well as the HI terminal.
10. Remove regulator cover screw from the HI outlet pres-
sure regulator adjust tower and turn screw clockwise
to increase pressure, or counterclockwise to decrease
pressure.
11. Turn off all electrical power and gas supply to the system.
12. Remove manometer hose from outlet pressure boss.
13. Turn outlet pressure test screw in to seal pressure port
(clockwise, 7 in-lb minimum).
14. Turn on electrical power and gas supply to the system.
15. Turn on system power and energize valve.
16. Using a leak detection solution or soap suds, check
for leaks at pressure boss screw. Bubbles forming in-
dicate a leak. SHUT OFF GAS AND FIX ALL LEAKS
IMMEDIATELY.
