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.

C. Condensate Trap Field Drain Attachment

Refer to Condensate Drain section for recommendations and procedures.

D.Pressure Switch Tubing

The LOWER collector box pressure tube (pink label) is factory connected to the pressure switch and should not require any modification.

NOTE: See Fig. 9 or tube routing label on main furnace door to check for proper connections.

E.Condensate Trap Freeze Protection

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

F.Construct a Working Platform

Construct working platform where all required furnace clearances are met. (See Fig. 3 and 10.)

CAUTION: The condensate trap MUST be installed below furnace. See Fig. 4 for dimensions. The drain connection to condensate trap must also be properly sloped to an open drain.

NOTE: Combustion-air and vent pipes are restricted to a mini- mum length of 5 ft. (See Table 6.)

NOTE: A 12-in. minimum offset pipe section is recommended with short (5 to 8 ft) vent systems. This recommendation is to reduce excessive condensate droplets from exiting the vent pipe. (See Fig. 10 or 29.)

V.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.

NOTE: In Canada, installations shall be in accordance with current NSCNGPIC Installation Codes and/or local codes.

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 or 11.

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 or 11.)

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

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