11. Turn gas supply manual shutoff valve to OFF position.

12. Turn off furnace power supply.

13. Remove manometer.

14. Apply pipe dope sparingly to end of inlet gas pipe plug and install in unused end of 1/8

″

tee. Use a small back-up wrench on tee when

tightening gas inlet pipe plug. (See Fig. 7A.)

PROCEDURE 8—MODIFY PRESSURE SWITCH WIRING

Modify Single Stage Pressure Switch Wiring

(Refer to furnace wiring diagram)

1. Disconnect yellow wire from pressure switch (PRS) on furnace inducer housing. Attach wire to C terminal on low gas pressure switch

(LGPS).

2. Connect insulated terminal of 16-in. yellow wire (provided in kit) to NO terminal on low gas pressure switch (LGPS). Connect other (flag

style insulated) end to the C terminal on furnace pressure switch (PRS) located on inducer housing.

3. Route wires along wire harness. Secure with wire tie provided in kit. Go to Procedure 9.

Modify 2-Stage and Variable Speed Pressure Switch Wiring

(Refer to furnace wiring diagram)

1. Disconnect orange wire from low-heat pressure switch LPS on inducer housing.

2. Connect un-insulated terminal of 1 orange wire (provided in kit) to splice connector. Connect other end to C terminal on low gas pressure

switch LGPS.

3. Connect insulated terminal of second orange wire (provided in kit) to NO terminal on low gas pressure switch LGPS. Connect other end

to pressure switch LPS located on inducer housing.

4. Route orange wires along wire harness. If possible, secure with wire tie provided in kit. Go to Procedure 9.

PROCEDURE 9—CHECK FURNACE OPERATION AND MAKE NECESSARY ADJUSTMENTS

1. Be sure main gas and electric supplies to furnace are off.

2. Remove 1/8-in. pipe plug from manifold pressure tap on downstream side of gas valve. (See Fig. 22A, 22B, 22C, or 22D.)

3. Attach manometer to manifold pressure tap on gas valve. (See Fig. 24.)

4. Turn gas supply manual shutoff valve to ON position.

5. Turn furnace gas valve switch to ON position.

6. Check all threaded pipe connections for gas leaks.
