2. Use smaller diameter tube (factory-supplied in loose parts

bag) to extend collector box pressure tube (green label)
which was previously connected to condensate trap relief
port connection.

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

sure switch connection labeled "collector box."

4. Use remaining smaller diameter tube (factory-supplied in

loose parts bag) to extend collector box pressure tube (pink
label) which was previously connected to pressure switch.

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.

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.

NOTE:

The auxiliary junction box (J-Box) MUST be relocated to

opposite side of furnace casing. (See Fig. 10.) See Electrical
Connection section for J-Box relocation.

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 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 and rotating trap.

3. 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.

4. Install condensate trap into 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).

Condensate Trap Tubing

NOTE:

See Fig. 10 or tube routing label on main furnace door to

check for proper connections.

1. Collector Box Drain Tube

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

parts bag) into collector box drain tube (blue label)
which was previously connected to condensate trap.

b. Connect large diameter drain tube and clamp (factory-

supplied in loose parts bag) to drain tube coupling,
extending collector box drain tube.

c. Route extended tube (blue label) to condensate trap and

cut to appropriate length.

d. Clamp tube to prevent any condensate leakage.
