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. For 92.1%
series, see
Figure 36 (page 46)
For 95.0% series, see
the J-trap, loosen the clamp on the drain tube, rotate the
J-trap to either side, and retighten the clamp.
Three general principles apply:
• Each condensate drain must be trapped separately 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 & clarifications to the general rules:
• 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 2,3,5,6,8,9,12
,13,16,17,19,20,21,23,24,31,32, & 34)
• In certain cases, it is permitted to drain the inducer back
into the top drain of the collector. This drain must not
sag in the middle. (Options 2,5,7,11,15,16,18,19,21,
23,25,27,29,30,32, & 33)

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.
