Refer to Condensate Drain section for recommendations and
procedures.
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. 7 or 8 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. 7 or 8 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. 7 or 8 or tube routing label on main furnace door
to check for proper connections.

Step 3—Downflow Applications
A downflow furnace application is where furnace blower is located
above combustion and controls section of furnace, and conditioned
air is discharged downwards.
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, 9, or 10.
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

3. Remove casing hole filler cap from casing hole. (See Fig. 2
4. Install casing hole filler cap (factory-supplied in loose parts

Casing hole filler cap must be installed in blower shelf hole
when condensate trap is relocated. Failure to follow this
