CONDENSATE TRAP LOCATION (ALTERNATE UPFLOW
ORIENTATION)
An alternate location for the condensate trap is the left-hand side
of casing. (See Fig. 2 and 8.)
NOTE: If the alternate left-hand side of casing location is used,
the factory-connected drain and relief port tubes must be discon-
nected and modified for attachment. See Condensate Trap Tubing
(Alternate Upflow Orientation) section for tubing attachment.
To relocate condensate trap to the left-hand side, perform the
following:
1. Remove 3 tubes connected to condensate trap.
2. Remove trap from blower shelf by gently pushing tabs inward
and rotating trap.
3. Install casing hole filler cap (factory-supplied in loose parts
bag) into blower shelf hole where trap was removed.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
Casing hole filler cap must be installed in blower shelf hole
when condensate trap is relocated to prevent combustion
products being drawn in from appliances in the equipment
room.
4. Install condensate trap into left-hand side casing hole by
inserting tube connection stubs through casing hole and

caps (factory-supplied in loose parts bag).
CONDENSATE TRAP TUBING (ALTERNATE UPFLOW
ORIENTATION)
NOTE: See Fig. 8 or tube routing label on main furnace door to
confirm location of these tubes.
1. Collector Box Drain Tube
Connect collector box drain tube (blue label) to condensate
trap.
NOTE: On 17-1/2-in. wide furnaces ONLY, cut tube between
corrugated sections to prevent kinks.
2. Inducer Housing Drain Tube
a. Remove and discard LOWER (molded) inducer housing
drain tube which was previously connected to condensate
trap.
b. Use inducer housing drain extension tube (violet label and
factory-supplied in loose parts bag) to connect LOWER
inducer housing drain connection to condensate trap.
c. Determine appropriate length, then cut and connect tube.
d. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
a. Connect relief port tube (green label) to condensate trap.
b. Extend this tube (if required) by splicing to small diameter
tube (factory-supplied in loose parts bag).
