(Shown with Blower Access Panel Removed)
PROCEDURE 2—UPFLOW APPLICATIONS
In an upflow application, the blower is located below the burner section, and conditioned air is discharged upwards.
A. Condensate Trap Location
The condensate trap is factory installed in the blower shelf and factory connected for UPFLOW applications. A
B. Condensate Trap Tubing
NOTE: See Fig. 5 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 applications. 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: a. Determine location of field drain connection. (See Fig. 2 or 5.)
NOTE: If internal filter or side Filter/Media Cabinet is used, drain tube should be located to opposite side of casing of return duct attachment to assist in filter removal.
b.Remove and discard casing drain hole plug button from desired side.
c.Install drain tube coupling grommet
d.Slide drain tube coupling
