Inducer & Venting Options; Inducer Assembly Rotation - Maytag *TC Installation Instructions Manual

*TC series furnaces are shipped with the bottom panel
installed. If furnace is installed horizontally, remove the
bottom panel from the furnace before attaching the duct
system. See Bottom Panel Removal section.
If installing the furnace in an attic, it is required that a drip
pan be placed under the furnace. If the installation is on a
combustible platform (Figure 12), it is recommended that
the drip pan extend at least 12 inches past the top and
front of the furnace.
If the furnace will be suspended from the ceiling, assemble
a support frame (Figure 13) using slotted iron channel
and full threaded rod. Fasten the frame together with nuts,
washers, and lockwashers. Secure the support frame to the
rafters with lag bolts. The furnace can also be suspended
using steel straps around each end of the furnace. The
straps should be attached to the furnace with sheet metal
screws and to the rafters with bolts.
It is recommended for further reduction of fi re hazard
that cement board or sheet metal be placed between the
furnace and the combustible fl oor and extend 12 inches
beyond the front of the door and top of the furnace.

Inducer & Venting Options
To increase installation fl exibility, the inducer assembly
can be rotated to 2 different positions. Each variation has
slightly different requirements with regard to condensate
disposal and, in some cases, the need to seal the furnace
cabinet. IMPORTANT NOTE: The Inducer Assembly
must never be positioned to vent downwards on
horizontal installs.
Before using Table 4 (page 19) the number of pipes (1-pipe
or 2-pipe) connected to the furnace must be known. Find
the proper furnace style (upfl ow, horizontal, or downfl ow)
and then the side that the pipes will exit from the furnace.
Finally select the option that properly matches your
installation type from Figures 38 - 40 (pages 47 - 49).
NOTE: It is important that Direct Vent (2-pipe) systems
maintain an airtight fl ow path from the air inlet to the fl ue
gas outlet. The furnace ships from the factory with two
holes in the cabinet for the air inlet and fl ue gas outlet.
In certain confi gurations, it is necessary to remove and
relocate a plastic cap in the furnace cabinet. If changing
the position of the air inlet and fl ue gas outlet, it is required
that the previous hole be closed off with the plastic cap to
maintain air tightness in the furnace. The hole locations
for *TC & *TL furnaces are shown in Figure 29 (page 33).

Inducer Assembly Rotation

WARNING:
Inducer rotation must be completed before
the furnace is connected to gas and electric. If
both utilities have been connected, follow the
shutdown procedures printed on the furnace
label and disconnect the electrical supply.
CAUTION:
It is good practice to label all wires prior
to disconnection. Wiring errors can cause
improper and dangerous operation.
1. Disconnect the electrical harness (1) from the inducer
assembly (2). See Figure 14 (page 18).
2. Remove the inducer assembly ground wire (3) from
the blower deck (4) or door.
3. Remove four screws (5) securing the inducer assembly
(2) to the header box (6).
4. Remove drain tube from inline drain assembly.
5. Rotate the inducer assembly (2) to its new position.
6. Secure the inducer assembly (2) to the header box
(6) by reinstalling the four screws (5) and the extra
screw provided in the parts package.
