FIGURE 5: Typical Suspended Furnace / Crawl Space Installation
During installation, doors should remain on the furnace when
moving or lifting.
When moving or handling this furnace prior to installation it is recom-
mended to leave the doors on the furnace to provide support and to
prevent damage or warping of the cabinet. When lifting the furnace,
support the ends of the furnace rather than lifting by the cabinet flanges
at the return air openings (bottom or sides) or supply air opening.
It is acceptable to use the primary heat exchanger tubes as a lifting
point provided that the tubes are lifted at the front of the heat exchang-
ers where attached to the vestibule panel. Do not use the top return
bend of the heat exchangers as lifting points as the tubes may shift out
of position or their location brackets/baffles.
DOWNFLOW APPLICATION
To apply the furnace in a downflow position, it will be necessary to
rotate the vent blower 90° left or right so that the vent pipe passes
through the side of the furnace casing rather than the end. See Figure
6.

COIL INSTALLATION
On all installations without a coil, a removable access panel is rec-
ommended in the outlet duct such that smoke or reflected light
would be observable inside the casing to indicate the presence of
leaks in the heat exchanger. This access cover shall be attached in
such a manner as to prevent leaks.

FURNACE ASSEMBLY - MC & FC SERIES COILS
These coils are factory shipped for installation in either upflow or down-
flow applications with no conversion.
Position the coil casing over or under the furnace opening as shown in
Figure 7 after configuring coil flanges as required see "Coil Flange" sec-
tion below.
COIL FLANGE INSTALLATION
The coils include removable flanges to allow proper fit up with furnaces
having various inlet and outlet flange configurations. The two flanges
are attached to the top of the coil in the factory during production. For
proper configuration of flanges refer to Figure 8.
