UPFLOW APPLICATIONS
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 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 the condensate 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.

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.
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.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door
to check for proper connections.
Upper Inducer Housing Drain Connection
Attached to the UPPER (unused) inducer housing drain connection
is a cap and clamp. This cap is used to prevent condensate leakage
in this application. Ensure this connection is capped.
NOTE: See Fig. 6 or 7 or tube routing label on main furnace door
to check for proper connections.
