hose clamps from the drain kit bag, attach the vent/flue pipe
and coupling to the induced draft blower. Secure the coupling
to the cabinet using the screws removed in step 1 or with
field-supplied 3/8” #8 self drilling screws.

ONNECTIONS
If the standard locations are undesirable for a specific installation,
alternate side panel locations are available on the upflow models for
the vent/flue. Counterflow furnaces include provisions for both alter-
nate vent/flue and combustion air piping. These locations may be of
particular benefit to upright upflow installations requiring additional
access to an A coil, or to upright counterflow installations requiring
additional access to a filter or electronic air cleaner, or to horizontal
installations desiring vent/flue (upflow and counterflow) and combus-
tion air intake (counterflow only) piping run vertically from the side of
the cabinet.
NOTE: Standard and alternate locations can be combined (i.e., an
installation may use the standard combustion air intake location
but use the alternate vent/flue location), if needed.
