11.1 EXHAUSTER ROTATION INSTRUCTIONS & PRESSURE SWITCH MOUNTING
H16.0.1
This furnace can be installed in any of the four positions. Figures 16 to 19 on the following pages shows the
four installation positions. The installer must consider the following services: gas pipe, electrical power, drain
trap, intake and exhaust vents. Also consider the air conditioning connections and drain, access to
fi
lter(s) and access to furnace and a/c for repair. Drains and traps of furnaces installed in spaces
subjected to freezing temperature must also be protected against freezing.
The combustion air inlet
fi
tting is a 2” PVC Socket to Pipe Thread adapter. Choose the intake
location and remove the appropriate plastic cap. Install the adapter to the exterior panel using the
gasket (on the outside of the panel and the locknut on the inside of the panel). Failure to apply
gasket on cabinet exterior voids the warranty.
H16.1.2
1. Disconnect exhauster wire connection.
2. Remove the 3 exhauster screws.
3. Remove pressure switch assembly (switches) and front manifold cover pressure sensing hose.
4. Remove
exhauster.
5. Reverse the bands on the rubber drain coupling so the screws are accessible if necessary. (Do not
reverse the drain coupling.) Con
fi
rm that directional arrow on drain coupling points away from exhauster.
6. Remove the appropriate plastic cap on the side panel. Install cap on vent opening not in use.
7. Reinstall the exhauster and the pressure switch assembly in the correct orientation with the (3) exhauster
screws removed in step 2. Reinstall the pressure switches so that they are above the heat exchanger
drain, to eliminate the chance of condensate draining into the pressure switch sensing hose causing
erratic furnace operation. See Figures 16-19 for reference. DO NOT USE POWER TOOL.
8. Rotate the drain coupling so the drain holes are angled downward 15° and tighten coupling band to
exhauster.
9. Complete the venting as installation requires.
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 HEAT EXCHANGER
DRAIN, AND CUT TO APPROPRIATE LENGTH TO PREVENT
ANY SAGS OR TRAPS FORMING IN THE HOSES.
