355CAV

APPLICATIONS

General

Some assembly and modifications are required for furnaces installed in any of the four applications shown in Fig. 1. All drain and pressure tubes are connected as shown in Fig. 7. See appropriate application instructions for these procedures.

!CAUTION

PROPERTY DAMAGE HAZARD

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 CAN/CSA-B149.1-05 and/or local codes.

UPFLOW APPLICATION

An upflow furnace application is where furnace blower is located below combustion and controls section of furnace, and conditioned air is discharged upwards.

Condensate Trap (Factory-Shipped Orientation)

The condensate trap is factory installed in the blower shelf and factory connected for UPFLOW applications. A factory-supplied tube is used to extend the condensate trap drain connection to the desired furnace side for field drain attachment. See Condensate Trap Tubing section for drain tube extension details. (See Fig. 6.)

Condensate Trap Tubing (Factory-Shipped Orientation)

NOTE: See Fig. 7 or tube routing label on main furnace door to confirm location of these tubes.

1.Collector Box Drain, Inducer Housing Drain, Relief Port, and Pressure Switch Tubes.

These tubes should be factory attached to condensate trap and pressure switch ready for use in UPFLOW applica- tions. These tubes can be identified by their connection location and also by a color label on each tube. These tubes are identified as follows: collector box drain tube (blue label), inducer housing drain tube (violet label or molded), relief port tube (green label), and pressure switch tube (pink label).

2.Condensate Trap Drain Tube

The condensate trap drain connection must be extended for field attachment by doing the following:

f.Determine location of field drain connection. (See Fig. 2 or 7.)

NOTE: If internal filter or side filter/media cabinet is used, drain tube should be located to opposite side of casing from return duct attachment to assist in filter removal.

g.Remove and discard casing drain hole plug button from desired side.

h.Install drain tube coupling grommet (factory-supplied in loose parts bag) in selected casing hole.

i.Slide drain tube coupling (factory-supplied in loose parts bag) through grommet so long end of coupling faces blower.

j.Cement 2 factory-supplied 1/2-in. (13 mm) street CPVC elbows to rigid drain tube connection on condensate trap. (See Fig. 7.) These elbows must be cemented together and cemented to condensate trap drain connection.
