!CAUTION

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.

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 rotaing 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

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.

5.Install condensate trap into left-hand side casing hole by inserting tube connection stubs through casing hole an rotating until tabls 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 DrainTube

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 collecor 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-suppled in loose parts bag).

b.Route extended collector box pressur tube to relief port connectio 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.
