Condensate Drain Lines

The placement of the condensate drain lines will depend
on the confi guration selected in Table 4 (page 18). The
drain lines can be routed out the left or right side of the
furnace, but must maintain a downward slope to ensure
proper condensate drainage. The J-trap may need to be
rotated to the side that matches your setup in Figures
38 - 40 (pages 47 - 49). To rotate the J-trap, loosen the
clamp on the drain tube, rotate the J-trap to either side,
and retighten the clamp.
Four general rules apply:
• Each condensate drain line must be separately trapped
using a J-Trap or fi eld supplied loop.
• There must always be a drain attached to the collector
at the outlet of the secondary heat exchanger.
• There must always be a drain at the outlet of the inducer
assembly.
• There must always be a drain at the lowest point of the
venting system.
Exceptions and clarifi cations to the general rules:
• In some cases, the lowest point in the vent system is
where it connects to the inducer (Options 6 & 8). In this
case one drain at this location is suffi cient.
• If the vent exits the furnace horizontally, the vent may
be turned vertically with a tee. The drip leg formed by
the tee must include a drain (Options 1-4, 9, 11, 12, 14).
• In certain cases, it is permitted to drain the inducer back
into the top drain of the collector (Options 1, 3, 5, 7, 9,
10, 12, & 13). To ensure proper drainage of condensate,
make sure the drain line does not sag or becomes
twisted. The drain tube supplied with the furnace may
need to be trimmed.
IMPORTANT NOTE: If the furnace is installed in an
area where temperatures fall below freezing, special
precautions must be made for insulating condensate
drain lines that drain to the outdoors. If condensate
freezes in the lines, this will cause improper operation
or damage to the furnace. It is recommended that all
drain lines on the outside of the residence be wrapped
with an industry approved insulation or material
allowed by local code.

Bottom Panel Removal

The steps listed below describe how to remove the bottom
panel from the furnace. See Figure 20.
1. Remove the door (1) from the blower compartment.
2. Disconnect the blower motor wiring harness (2) from
the control board.
3. Remove two screws (3) securing the blower assembly
(4) to the furnace.
4. Carefully pull the blower assembly (4) out thru the
front of the furnace.
5. Remove all screws (5) securing bottom panel (6) to
bottom of furnace and front brace (7).

6. Lift up and slide bottom panel (6) out through front of
furnace.
7. Reinstall the blower assembly (4) in reverse order.

Alternate Bottom Panel Removal

If the bottom panel cannot be removed using the previous
instructions, the steps below are an alternate method for
removing the bottom panel. (See Figure 21).
1. Remove the door (1) from the blower compartment
2. Remove all screws securing the bottom panel (2) to
the front brace (3).
3. Remove two screws (4) securing the furnace cabinet
to the blower deck (5).
4. Remove all screws (6) securing the furnace cabinet
to the bottom panel (2).
5. Remove the screw (7) securing the bottom corner of
the furnace cabinet to the front brace (3).
6. Carefully spread the bottom corner of the furnace
cabinet outwards while sliding the bottom panel (2)
out through the front of the furnace.
7. Reassemble the furnace in reverse order.
