CONDENSATE TRAP LOCATION (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 (Factory-Shipped Orientation) 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 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
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.
b. Remove and discard casing drain hole plug button from
desired side.
c. Install drain tube coupling grommet (factory-supplied in
loose parts bag) in selected casing hole.
d. Slide drain tube coupling (factory-supplied in loose parts
bag) through grommet so long end of coupling faces
blower.
e. Cement 2 factory-supplied 1/2-in. 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.
NOTE: Failure to use CPVC elbows may allow drain to kink,
preventing draining.
f. Connect larger diameter drain tube and clamp (factory-
supplied in loose parts bag) to condensate trap and clamp
securely.
g. Route tube to coupling and cut to appropriate length.
h. Attach tube to coupling and clamp securely.
