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 9.
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
9.)
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.
CONDENSATE TRAP TUBING
NOTE: See Fig. 9 or tube routing label on main furnace door to
check for proper connections.
1. Collector Box Drain Tube
a. Install drain tube coupling (factory-supplied in loose parts
bag) into collector box drain tube (blue label) which was
previously connected to condensate trap.
b. Connect large diameter drain tube and clamp (factory-
supplied in loose parts bag) to drain tube coupling, extend-
ing collector box drain tube.
c. Route extended tube (blue label) to condensate trap and cut
to appropriate length.

d. Clamp tube to prevent any condensate leakage.
2. Inducer Housing Drain Tube
a. Remove and discard LOWER (molded) inducer housing
drain tube which was previously connected to condensate
trap.
b. Use inducer housing drain extension tube (violet label and
factory-supplied in loose parts bag) to connect LOWER
inducer housing drain connection to the condensate trap.
c. Determine appropriate length, cut, and connect tube.
d. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
a. Extend collector box tube (green label) which was previ-
ously connected to the condensate trap by splicing to small
diameter tube (factory-supplied in loose parts bag).
b. Route extended collector box pressure tube to relief port
connection on the condensate trap.
c. Determine appropriate length, cut, and connect tube.
d. Clamp tube to prevent any condensate leakage.

Refer to Condensate Drain section for recommendations and
procedures.
PRESSURE SWITCH TUBING
The LOWER collector box pressure tube (pink label) is factory
connected to the pressure switch for use when furnace is installed
in UPFLOW applications. This tube MUST be disconnected,
extended, rerouted, and then reconnected to the pressure switch in
HORIZONTAL LEFT applications.
