CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury or

death.

To route the vent pipe and combustion air pipe through the

furnace, the manufacturer supplied kit must be used. Failure

to properly seal the blower compartment from the furnace

vestibule could result in the circulation of carbon monoxide

throughout the structure. The vent pipe and combustion air

pipe must be a continuous pipe while passing through the

blower compartment. Seals supplied in this kit must be

installed per the instructions provided. Follow all procedures

outlined in these instructions.

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.

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 Figure 54 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 in the vent elbow to align it with the

inducer for each orientation.

3. Tighten the clamp around the vent elbow. Torque the

clamp to 15 Ib-in. See Figure 40 through Figure 45,

Figure 55 and Figure 56.
