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.
WARNING: Casing hole filler cap must be installed in
blower shelf hole when condensate trap is relocated.
Failure to follow this warning could result in electrical
shock, fire, personal injury, or death.
4. Install condensate trap into left-hand side casing hole by
inserting tube connection stubs through casing hole and
rotating until tabs snap into locking position.
5. Fill unused condensate trap casing holes with plastic filler

D. Condensate Trap Tubing (Alternate Upflow
Orientation)
NOTE: See Fig. 7 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 from occurring.
2. Inducer Housing Drain Tube
a. Remove and discard LOWER (molded) inducer housing
drain tube which was previously connected to conden-
sate 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 the con-
densate trap.
c. Determine appropriate length, 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).
c. Determine appropriate length, cut, and connect tube.
E. Condensate Trap Field Drain Attachment
Refer to Condensate Drain section for recommendations and
procedures.
F. Pressure Switch Tubing
The LOWER collector box pressure tube (pink label) is factory
connected to the pressure switch and should not require any
modification.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door
to check for proper connections.
G. Upper Collector Box and Inducer Housing (Unused)
Drain Connections
UPPER COLLECTOR BOX DRAIN CONNECTION
Attached to the UPPER collector box drain connection is a
factory-installed corrugated, plugged tube (blue and white striped
label). This tube is plugged to prevent condensate leakage in this
application. Ensure this tube is plugged.
