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.

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, 9, or 10.

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 in- ward and rotating trap.

3.Remove casing hole filler cap from casing hole. (See Fig. 2 and 10.)

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 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. 9 or 10 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 con- densate trap.

c.Connect LOWER collector box drain connection to con- densate trap.

(3.) 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. (4.) 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 previ- ously plugged.

(b.)Connect larger diameter drain tube (factory-sup- plied in loose parts bag) to drain tube coupling, extending collector box drain tube for connec- tion to condensate trap.

(c.)Route extended collector box drain tube between gas valve and inlet housing as shown in Fig. 10.

(d.)Determine appropriate length and cut. (e.)Connect to condensate trap.

2.Inducer Housing Drain Tube

a.Remove factory-installed cap and clamp from LOWER inducer housing drain connection.
