Inducer Assembly Rotation
WARNING:
CAUTION:
1. Disconnect the electrical harness from the inducer
assembly.
2.Remove the inducer assembly ground wire from the
blower deck.
3. Remove 3 screws securing the inducer assembly to the
header box.
4.Rotate the inducer assembly to its new position.
5. Secure the inducer assembly to the header box by
reinstalling the three screws. If the inducer assembly
is rotated to the left or right side of the furnace, use the
extra screw provided in the parts package.
6. Remove the cabinet plug from side of furnace and
reinstall in hole on opposite side of cabinet.
7.Install in-line drain assembly and tubing.
8. Install all condensate drain lines. For GUH92A &
GDD92A furnaces see Figure 35, Figure 36, Figure 37,
Figure 38, or Figure 39. For GUH95A, GUH95C & GDD95A
furnaces see Figure 41, Figure 42, or Figure 43.
9. Reconnect the electrical harness to the inducer
assembly.
10. Reconnect the inducer assembly ground wire to the
blower deck or door.
11. Verify operation as detailed on the furnace label.
Pressure Switch Tubing
All upflow / horizontal furnaces have two switches, one
connected to the static tap on the inducer assembly and
the other to the collector box. Figure 15 & Figure 16 display
the proper routing of pressure switch tubing for GUH92A,
GUH95A & GUH95C furnaces. Downflow (GDD92A &
GDD95A) furnaces require only one switch connected to
the inducer’s static tap as shown in
Figure 17.
Alternate Pressure Switch Location
In some inducer orientations, the inducer pressure switch
may interfere with gas pipe installation. Determine the
side of the cabinet the gas pipe will enter and see if the
inducer pressure switch needs to be moved. If the pressure
switch interferes with the gas pipe, use these instructions
for relocating it to an alternate location:
