A. Condensate Trap Location
The condensate trap must be removed from the factory-installed
blower shelf location and relocated in selected application location
as shown in Fig. 2 or 11.
To relocate condensate trap from the blower shelf to desired
location, 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.
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
caps (factory-supplied in loose parts bag).
B. Condensate Trap Tubing
NOTE: See Fig. 11 or tube routing label on main furnace door to
check for proper connections.
1. Collector Box Drain Tube
a. Remove factory-installed plug from LOWER collector
box drain tube (blue and white striped label).
b. Install removed clamp and plug into UPPER collector
box drain tube (blue label) which was previously con-
nected to condensate trap.
c. Connect LOWER collector box drain tube (blue and
white striped label) to condensate trap. Tube does not
need to be cut.

d. Clamp tube to prevent any condensate leakage.
2. Inducer Housing Drain Tube
a. Remove factory-installed cap and clamp from LOWER
inducer housing drain connection.
b. Remove and discard UPPER (molded) inducer housing
drain tube which was previously connected to conden-
sate trap.
c. Install cap and clamp on UPPER inducer housing drain
connection where molded drain tube was removed.
d. Use inducer housing drain extension tube (violet label
and factory-supplied in loose parts bag) to connect
LOWER inducer housing drain connection to conden-
sate trap.
e. Determine appropriate length, cut, and connect tube to
condensate trap.
f. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
Refer to Pressure Switch Tubing section for connection
procedure.
C. Condensate Trap Field Drain Attachment
Refer to Condensate Drain section for recommendations and
procedures.
D. Pressure Switch Tubing
One collector box pressure tube (pink label) is factory connected to
the pressure switch for use when furnace is installed in UPFLOW
applications. This tube MUST be disconnected and used for the
condensate trap relief port tube. The other collector box pressure
