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. Inlet pressure tap connections:
a. White-Rodgers Valve:
Back inlet pressure test screw (inlet pressure tap
out one turn (counterclockwise, not more than one
turn).
2. Connect manometer (or appropriate pressure gauge)
at either the gas valve inlet pressure tap or the gas
piping drip leg. See White-Rodgers 36J22Y-204 gas
valve for location of inlet pressure tap.
3. Turn ON the gas supply.
4. Turn On power and operate the furnace and all other
gas consuming appliances on the same gas supply
line.
5. Using a leak detection solution or soap suds, check for
leaks at screw (White-Rodgers valve). Bubbles forming
indicate a leak. SHUT OFF GAS AND REPAIR ALL
LEAKS IMMEDIATELY!
6.
Measure the gas supply pressure with burners firing.
Adjust supply pressure using the
Inlet Gas Supply
Pressure
table shown below. If supply pressure
reading differs from the table, make necessary
adjustments to pressure regulator, gas piping size,
etc., and/or consult with local gas utility.

7. Turn OFF all electrical power and gas supply to the
system.
8. Remove the manometer hose from the hose barb
fitting or inlet pressure Tap.
9. Replace inlet pressure tap:
a. White-Rodgers Valve: Turn inlet pressure test
screw in to seal pressure port (clockwise, 7 in-lb
minimum).
10. Retest for leaks. If bubbles form, shut down gas and
repair leaks immediately.
11. If there are no leaks, turn ON electrical power and gas
supply to the system.
12. Turn valve switch ON.
NOTE: If measuring gas pressure at the drip leg, a
field-supplied hose barb fitting must be installed
prior to making the hose connection. If using
the inlet pressure Tap on the White-Rodgers gas
valve, then use the 36G/J Valve Pressure Check Kit,
Goodman Part No. 0151K00000S.

Measuring Inlet Gas Pressure (Alt. Method)
Gas Manifold Pressure Measurement and
Adjustment
CAUTION
To prevent unreliable operation or equipment damage, the
gas manifold pressure must be as specified on the unit rating
plate. Only minor adjustments should be made by adjusting
the gas valve pressure regulator.
Only small variations in gas pressure should be made by
adjusting the gas valve pressure regulator. The manifold
pressure must be measured with the burners operating.
To measure and adjust the manifold pressure, use the
following procedure.
