(a.) Install drain tube coupling (factory-supplied in

loose parts bag) into collector box drain tube
(blue and white striped label) which was pre-
viously plugged.

(b.) Connect larger diameter drain tube (factory-

supplied in loose parts bag) to drain tube
coupling, extending collector box drain tube
for connection to condensate trap.

(c.) Route extended collector box drain tube di-

rectly from collector box drain to condensate
trap as shown in Fig. 10.

(d.) Determine appropriate length and cut.

(e.) Connect to condensate trap.

(f.) Clamp tube to prevent any condensate leakage.

2. Inducer Housing Drain Tube

a. Remove factory-installed cap and clamp from LOWER

inducer housing drain connection.

b. Remove and discard UPPER (molded) inducer housing

drain tube which was previously connected to conden-
sate trap.

c. Install cap and clamp on UPPER inducer housing drain

connection where molded drain tube was removed.

d. Use inducer housing drain tube (violet label and factory-

supplied in loose parts bag) to connect LOWER inducer
housing drain connection to the condensate trap.

e. Connect inducer housing drain connection to condensate

trap.

(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 drain to conden-
sate trap as shown in Fig. 8.

(b.) Determine appropriate length and cut.

(c.) Connect tube to condensate trap.

(d.) Clamp tube to prevent any condensate leakage.

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
or HORIZONTAL LEFT applications. This tube MUST be dis-
connected 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 HORIZON-
TAL RIGHT applications.

NOTE:

See Fig. 9 or 10 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 connec-
tion by splicing to small diameter tube (factory-supplied in
loose parts bag).

3. Connect collector box pressure tube (green label) to pres-

sure 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.

Condensate Trap Freeze Protection

Refer to Condensate Drain Protection section for recommenda-
tions and procedures.

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.

CAUTION:

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.

A.

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 11.

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. Remove casing hole filler cap from casing hole. (See Fig. 2

or 11.)

4. Install casing hole filler cap (factory-supplied in loose parts

bag) into blower shelf hole where trap was removed.

WARNING:

Casing hole filler cap must be installed in

blower shelf hole when condensate trap is relocated.
Failure to follow this warning could result in electrical
shock, fire, personal injury or death.

5. 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.

6. Fill unused condenstate trap casing holes with plastic filler

caps (factory-supplied in loose parts bag).
