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.

Step 3 - - Downflow Applications
In a downflow furnace application, the blower is located above
the burner section, 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, 8 or 9.
