NOTE
• Condensate drain tubing must be cut to
appropriate length and slopping towards
IOM
IOM
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.
• Any increase of venting diameter must
be done on the vertical sections NOT
horizontal sections.
11.3 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 Figures 16-20 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.
