Condensate Drain Lines
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.
The placement of the condensate drain lines will depend
on the configuration selected in
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
Figure 37 (page
&
Figure 39 (page
48). To rotate the J-trap, loosen the
clamp on the drain tube, rotate the J-trap to either side,
and retighten the clamp.
Three general rules apply:
• Each condensate drain line must be separately trapped
using a J-Trap or field supplied loop. After individually
trapping the condensate lines, it is acceptable to combine
the drains.
• 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 lowest point of the
venting system. NOTE: If using a condensate pump, the
furnace drain line must be installed above the pumps
water line.
Exceptions and clarifications 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 sufficient.
• 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.
Bottom Panel Removal
The steps listed below describe how to remove the bottom
panel from the furnace. See
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
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.
