e. Connect inducer housing drain connection to
condensate trap.
(1.) Condensate Trap Located on Left Side of Casing
a. Determine appropriate length and cut.
b. Connect tube to condensate trap.
c. Clamp tube to prevent any condensate leakage.
(2.) Condensate Trap Located on Right Side of Casing
a. Route inducer housing drain tube (violet label)
directly from inducer housing to condensate
trap as shown in Fig. 9.
b. Determine appropriate length and cut.
c. Connect tube to condensate trap.
d. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
Refer to Pressure Switch Tubing section for connection
procedure.
CONDENSATE TRAP FIELD DRAIN ATTACHMENT
Refer to Condensate Drain section for recommendations
and procedures.
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 tube (green label) which was factory connected to
the condensate trap relief port connection MUST be connected to
the pressure switch in DOWNFLOW or HORIZONTAL
RIGHT applications.
NOTE
: See Fig. 8 or 9 or tube routing label on main furnace
door to check for proper connections.
Relocate tubes as described below.
1. Disconnect collector box pressure tube (pink label)
attached to pressure switch.
2. Extend collector box pressure tube (green label) which
was previously connected to condensate trap relief port
connection
by
splicing
to
small
diameter tube
(factory-supplied in loose parts bag).
3. Connect collector box pressure tube (green label) to
pressure switch connection labeled COLLECTOR BOX.
4. Extend collector box pressure tube (pink label) which was
previously connected to pressure switch by splicing to
remaining small diameter tube (factory-supplied in loose
parts bag).
5. Route this extended tube (pink label) to condensate trap
relief port connection.
6. Determine appropriate length, cut, and connect tube.
7. Clamp tube to relief port connection.

Step 4 -- Horizontal Left (Supply-Air Discharge)
Applications
A horizontal left furnace application is where furnace blower is
located to the right of combustion and controls section of furnace,
and conditioned air is discharged to the left.
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 10.
