Install the Vent and Combustion Air Pipes
With the furnace installed in the required position, remove the desired
knockouts from the casing. It will be necessary to remove one knockout
for the vent pipe and the other knockout for the combustion air
connection (see Fig. 12).
Use a flat blade screwdriver and tap on the knockout on opposite sides,
where the knockout meets the casing. Fold the knockout down with duct
pliers and work the knockout back and forth until it is removed. Trim
any excess metal from the knockout with tin snips.
The vent elbow can be rotated to the required location on the casing if
necessary (see Fig. 58). To rotate the vent elbow:
1. Loosen the clamp on the inlet of the vent elbow attached to the
inducer.
2. Rotate the vent elbow to the required position. There are rounded
notches on the vent elbow to align it with the inducer housing for
each orientation.
3. Tighten the clamp around the vent elbow. Torque the clamp to 15
lb-in. (see Fig. 54 through
