PROPERTY DAMAGE
Failure to follow this caution may result in property

damage.
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.

CAUTION

!

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 11.
To relocate condensate trap from the blower shelf to desired
location, perform the following:

1. Remove three 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.

CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal

injury or death.
Casing hole filler cap must be installed in blower shelf hole

when condensate trap is relocated to prevent combustion

products being drawn in from appliances in the equipment

room.

!

WARNING

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 condensate trap casing holes with plastic filler

caps (factory--supplied in loose parts bag).

Condensate Trap Tubing

NOTE: See Fig. 11 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.

2. Inducer Housing Drain Tube

a. Remove and discard LOWER (molded) inducer

housing drain tube which was previously

connected to condensate trap.

b. Use inducer housing drain extension tube (violet

label and factory--supplied in loose parts bag) to

connect

LOWER inducer

housing

drain

connection to condensate trap.

c. Determine appropriate length, cut and connect

tube.

d. Clamp tube to prevent any condensate leakage.

3. Relief Port Tube

a. Extend collector box tube (green label) which was

previously connected to condensate trap by splicing to
small diameter tube (factory--supplied in loose parts
bag).

b. Route extended collector box pressure tube to relief port

connection on condensate trap.

c. Determine appropriate length, cut, and connect tube.

d. Clamp tube to prevent any condensate leakage.

Condensate Trap Field Drain Attachment

Refer to Condensate Drain section for recommendations and
procedures.

Pressure Switch Tubing

The LOWER collector box pressure tube (pink label) is factory

connected to the High Pressure Switch for use when furnace is
installed in UPFLOW applications.

This tube MUST be

disconnected, extended rerouted, and then reconnected to the
pressure switch in HORIZONTAL LEFT applications for 060 and

080 heating input furnaces.
NOTE: See Fig. 11 or tube routing label on main furnace door to
check for proper connections.
Modify tube as described below.

1. Disconnect collector box pressure tube (pink label) attached

to High Pressure Switch.

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

bag) to extend tube disconnected in Item 1.

3. Route extended tube:

a. Behind inducer housing.

b. Between blower shelf and inducer housing.

4. Determine appropriate length, cut, and reconnect tube to

High Pressure Switch connections labeled COLLECTOR

BOX.

Condensate Trap Freeze Protection

Refer to Condensate Drain Protection section for recommendations

and procedures.

Construct a Working Platform

Construct working platform where all required furnace clearances
are met. (See Fig. 3 and 12 or 13.)

UNIT OPERATION HAZARD
Failure to follow this caution may result in intermittent unit

operation.
The condensate trap MUST be installed below furnace. See

Fig. 6 for dimensions. The drain connection to condensate

trap must also be properly sloped to an open drain.

CAUTION

!

NOTE: A 12--in. (305 mm) minimum offset pipe section is
recommended with short (5 to 8 ft. or 1.5M to 2.4M) vent systems.
This recommendation is to reduce excessive condensate droplets
from exiting the vent pipe. (See Fig. 12, 13, or 44.)
