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 remain-
ing 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.

Local codes may require a drain pan under entire furnace and
condensate trap when a condensing furnace is used in an attic
application or over a finished ceiling.
NOTE: In Canada, installations shall be in accordance with
current NSCNGPIC and/or local codes.

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 9.
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).
