NOTE: See Fig. 5 or 6 or tube routing label on main furnace door to check for proper connections.

H.Condensate Trap Freeze Protection

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

III.DOWNFLOW APPLICATIONS

A downflow furnace application is where furnace blower is located above combustion and controls section of furnace, and conditioned air is discharged downwards.

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, 7, or 8.

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, 7, or 8.)

4.Install casing hole filler cap into blower shelf hole where trap was removed.

5.Install condensate trap into desired casing hole by inserting tube connection stubs through casing hole and rotating until tabs snap into locking position.

B.Condensate Trap Tubing

NOTE: See Fig. 7 or 8 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 connected to condensate trap.

c. Connect LOWER collector box drain connection to condensate trap.

(1.) Condensate Trap Located on Left Side of Casing

(a.) Connect LOWER collector box drain tube (blue and white striped label) to condensate trap. Tube does not need to be cut.

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

(2.) Condensate Trap Located on Right Side of Casing

(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 be- tween gas valve and inlet housing as shown in Fig. 8.

(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.
