UPFLOW INSTALLATION

Standoffs and screws (See Figure 1) are included with the
cased coils for attachment to the furnace. There are clearance
alignment holes near the bottom of the coil wrapper. Drill
screws are used to engage the furnace top flanges. The
standoff is inserted into the cabinet alignment hole. The drill
screws are inserted through the standoffs then screwed into
the furnace flange. The coil is always placed downstream of
the furnace airflow.

WARNING
!
Do not install the furnace directly on carpeting, tile or other
combustible material other than wood flooring. For vertical
downflow application, subbase (BAYBASE205) must be
used between the furnace and combustible flooring. When
the downflow furnace is installed vertically with a cased
coil, a subbase is not required.

HORIZONTAL INSTALLATION
The coil and furnace must be fully supported when used in
the horizontal position. It is always recommended that an
auxiliary drain pan be installed under a horizontally in-
stalled evaporator coil or 90% gas furnace. Connect the
auxiliary drain line to a separate drain line (no trap is
needed in this line).
Three brackets (with screws) are included with downflow
furnaces for installation to stabilize and secure the furnace
and TXC cased coil in the horizontal position. See
Figure 4. The coil is placed downstream of the furnace, with
the apex of the coil pointing in the direction of the airflow for
horizontal installation. The cased coil is secured to the
furnace and both the furnace and the cased coil must be
properly supported. The brackets mount using the rear
screws on the coil case and use the screws provided to secure
the bracket to the furnace. The remaining bracket is placed
as close to center as possible (horizontally) between the coil
case front and the furnace bottom channel (for downflow/
horizontal furnace). Use four of the screws provided to
secure the bracket. The upflow furnace, converted to horizon-
tal, aligns and attaches the TXC coil as in Figure 1. However,
the coil requires additional support.

The furnace may be installed in an attic or crawl space in the
horizontal position by placing the furnace on the left side (as
viewed from the front in the vertical position). The horizon-
tal furnace installation in an attic should be on a service
platform large enough to allow for proper clearances on all
sides and service access to the front of the furnace (See
Figure 5 & Clearance Tables, pages 4-5). Line contact is only
permissible between lines formed by intersections of the top
and two sides of the furnace casing and building joists, studs,
or framing.
The furnace may be placed horizontally in a crawl space on a
pad or other noncombustible material which will raise the
unit for sufficient protection from moisture. The furnace
must be supported at both ends and the middle when
installed horizontally. The furnace must also be
elevated approximately 4-6 inches to allow clearance
for the condensate drain to exit the cabinet in the
horizontal position.
The horizontal furnace may also be suspended from the joists
using 3/8" all-thread rods with pieces of angle iron under-
neath the furnace to form a hanging rack at both ends and
the midpoint. The rods need to be of sufficient length to
allow for proper clearances from combustible materials. The
angle iron needs to be at least 32" in length to allow for
access to service panels.
