2. Apply pipe dope sparingly to threaded end of street elbow (provided in kit) and install elbow on nipple. Finger tighten. Use a small pipe
wrench for final tightening.
3. Point male end of street elbow so it matches the orientation relative to gas valve shown in Fig. 19.
4. Install propane low gas pressure switch (provided in kit) on street elbow. After switch has been finger tightened, use small wrench on base
of pressure switch for final tightening. When pressure switch is tight, switch terminals should point as shown in Fig. 19 relative to gas valve.
5. Apply pipe dope sparingly to end of inlet gas pipe and reconnect pipe to gas valve.
PROCEDURE 7—MODIFY PRESSURE SWITCH WIRING
1. Disconnect orange wire from low-heat pressure switch LPS on inducer housing. Add 1/4-in. splice connector to this wire.
2. Connect uninsulated terminal of 1 orange wire (provided in kit) to splice connector. Connect other end to C terminal on low gas pressure
switch LGPS on gas valve.
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. Secure with wire tie provided in kit.
PROCEDURE 8—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. 11.)
3. Attach manometer to manifold pressure tap on gas valve. (See Figs. 11 and 17.)
