appropriate length and slopping towards
condensate trap, ensuring that drain hoses do
not create traps prior to the condensate trap
assembly.
•
Condensate trap must be primed with water prior
to initial furnace start up.

Barbed fi ttings must be fully inserted into
condensate trap, seated to barb fl ange.

EXHAUSTER ROTATION INSTRUCTIONS & PRESSURE SWITCH MOUNTING
1. Loosen collar clamp and pull up exhaust pipe for adequate clearance.
2. Disconnect exhauster wire connection.
3. Remove the 4 exhauster screws.
4. Remove pressure switch assembly (switches) and front manifold cover pressure sensing hose.
5. Remove exhauster.
6. Reverse the bands on the rubber drain coupling so the screws are accessible if necessary. (Do not
reverse the drain coupling.) Confi rm that directional arrow on drain coupling points away from exhauster.
7. Remove the appropriate plastic cap on the side panel. Install cap on vent opening not in use.
8. Reinstall the exhauster and the pressure switch assembly in the correct orientation with the (4) exhauster
screws removed in step 2. DO NOT USE POWER TOOL. Reinstall the pressure switches so that they
are above the front manifold drain, to eliminate the chance of condensate draining into the pressure
switch sensing hose causing erratic furnace operation. See Figure 16 for reference.
9. Rotate the drain coupling so the drain holes are angled downward 15° and tighten coupling band to
exhauster.
10. Complete the venting as installation requires, mounting the exhaust pipe and tightly secure to collar.
Always secure or support the vent and intake to the fl oor joists or rafters to avoid sagging and possible fatigue
of venting materials. This ensures proper drainage and prevents spilling the products of combustion into the
building.
The blower compartment should be completely isolated from the burner compartment, and in tight rooms with
other combustion devices, be completely isolated from the room. Ensure that the combustion door gasket is in
good condition.
IMPORTANT:
KEEP PRESSURE SWITCH HOSES ABOVE FRONT MANIFOLD
DRAIN, AND CUT TO APPROPRIATE LENGTH TO PREVENT ANY
SAGS OR TRAPS FORMING IN THE HOSES.
