NOTE:

A 12-in. minimum horizontal pipe section is recom-

mended with short (5 to 8 ft) vent systems. This recommendation
is to reduce excessive condensate droplets from exiting the vent
pipe. (See Fig. 11 or 38.)

HORIZONTAL RIGHT (SUPPLY-AIR DISCHARGE)

APPLICATIONS

A horizontal right furnace application is where furnace blower is
located to the left of combustion and controls section of furnace,
and conditioned air is discharged to the right.

CAUTION:

Local codes may require a drain pan under

entire furnace and condensate trap when a condensing
furnace is used in attic application or over a finished
ceiling. Failure to follow this caution will result in minor
property damage.

NOTE:

In Canada, installations shall be in accordance with

current NSCNGPIC Installation Codes 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 12.

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 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).

Condensate Trap Tubing

NOTE:

See Fig. 12 or tube routing label on main furnace door to

check for proper connections.

1. Collector Box Drain Tube

a. Remove factory-installed plug from LOWER collector

box drain tube (blue and white striped label).

b. Install removed clamp and plug into UPPER collector

box drain tube (blue label) which was previously con-
nected to condensate trap.

c. Connect LOWER collector box drain tube (blue and

white striped label) to condensate trap. Tube does not
need to be cut.

d. 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.
