5. Move the furnace gas valve manual control to the OFF
position.
6. Wait five minutes then smell for gas. Be sure check near
the floor as some types of gas are heavier than air.
7. If you smell gas after five minutes, immediately follow
the safety instructions in the Safety Considerations on
page 3 of this manual. If you do not smell gas after five
minutes, move the furnace gas valve manual control to
the ON position.
8. Replace the burner compartment door.
9. Open the manual gas shutoff valve external to the furnace.
10. Turn on the electrical power to the furnace.
11. Adjust the thermostat to a setting above room temperature.
12. After the burners are lit, set the thermostat to desired
temperature.

urnACe hutdown
1. Set the thermostat to the lowest setting.
The integrated control will close the gas valve and
extinguish flame. Following a 15 second delay, the induced
draft blower will be de-energized. After the blower off delay
time expires, the blower de-energizes.
2. Remove the burner compartment door and move the
furnace gas valve manual control to the OFF position.
3. Close the manual gas shutoff valve external to the
furnace.
4. Replace the burner compartment door.

OPERATING
The line pressure supplied to the gas valve must be within the
range specified below. The supply pressure can be measured at
the gas valve inlet pressure tap or at a hose fitting 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 firing.
Supply pressure must be within the range specified 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
