than the original tubing ID supplied by the manufacturer.
The drain line should slope downward away from the
furnace to ensure proper drainage.
• 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.
For J951X*U series, see
. For J951X*D series, see

tube, rotate the J-trap to either side, and retighten the
clamp.
• It is permissible to locate the trap away from the
furnace. The condensate drain system (J-trap and drain
tube) should be no more than 30 equivalent feet while
maintaining 1/4" per foot slope, and insulated if located in
an unconditioned space.
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. (Option 1, Option 3, Option 4,
Option 11, Option 12, & Option 14)
• 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. (Option 1, Option 3, Option 5, Option
7, Option 9, Option 10, Option 12, & Option 13)
