6. FURNACE IN HORIZONTAL RIGHT POSITION
A
CAUTION
Both the coil and furnace must be fully supported. Do not
attempt to suspend the coil using only the brackets.
The non-condensing furnaces may be laid on either side for
horizontal application.
The condensing downflow/horizontal and upflow/horizontal
furnaces may not be rotated onto their right side.
Connection brackets for coil/furnace alignment are included
with the furnaces.
a. Horizontal right: For the horizontal right configuration
in non-condensing furnaces only, the two-piece factory
baffle must be removed and the top baffle replaced for
the following models: 4TXCB004, 4TXCC005, 4TX-
CC006, 4TXCC007, and 4TXCC008.
b. Replacing the factory installed baffle.
1. Remove the factory installed two-piece baffle assem-
bly (see Figure 4) from the apex of the coil by removing
the 5/16" hex head screws. Discard the bottom half of
the baffle.
2. Replace the top baffle using the screws removed
previously (see Figure 8).
3. Figure 9 shows the baffle change necessary for hori-
zontal right application.
IMPORTANT:
The 4TXC cased coil must be placed downstream of the
furnace, with the apex of the coil always pointing opposite
the direction of the airflow for horizontal right installation.
This placement supersedes previous furnace Installer's
Guide stating install "with the apex of the coil pointing in
the direction of airflow for horizontal application." See
Figure 10.

c. When the noncondensing Upflow/Horizontal furnace is
placed on its right side for right airflow, the furnace top
flange meets the cased coil top flange. The coil flange
fits inside of the furnace flange. See Figure 11.
There are three holes in the furnace top flange which
can be used for pilot holes to connect and align the
furnace and coil. There are self drilling screws included
which can be used for this connection. Seal all gaps
between the furnace and coil.
