INLET GAS SUPPLY PRESSURE
CAUTION
TO PREVENT UNRELIABLE OPERATION OR EQUIPMENT DAMAGE, THE
INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT
RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES
OPERATING.
The line pressure supplied to the gas valve must be within the
range specied below. The supply pressure can be measured at
the gas valve inlet pressure tap or at a hose tting installed in
the gas piping drip leg. The supply pressure must be mea-
sured with the burners operating. To measure the gas supply
pressure, use the following procedure.
1. Turn OFF gas to furnace at the manual gas shutoff valve
external to the furnace.
2. Connect a calibrated water manometer (or appropriate gas
pressure gauge) at either the gas valve inlet pressure tap
or the gas piping drip leg. See White-Rodgers 36J54
gas valve (Figure 43B) fto locate the inlet pressure tap.
NOTE: If using the inlet pressure tap on the White-Rodgers
36J54 gas valve, then use the 36G/J Valve Pressure Check
Kit, Part No. 0151K00000S.
3. Turn ON the gas supply and operate the furnace and all
other gas consuming appliances on the same gas supply
line.
4. Measure furnace gas supply pressure with burners ring.
Supply pressure must be within the range specied in the
Inlet Gas Supply Pressure table.
If supply pressure differs from table, make the necessary adjust-
ments to pressure regulator, gas piping size, etc., and/or consult
with local gas utility.
5. Turn OFF gas to furnace at the manual shutoff valve and
disconnect manometer. Reinstall plug before turning on
gas to furnace.
6. Turn OFF any unnecessary gas appliances stated in step
three.

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.
