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 (factory-supplied in loose parts
bag) into blower shelf hole where trap was removed.

CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
Casing hole filler cap must be installed in blower shelf hole
when condensate trap is relocated to prevent combustion
products being drawn in from appliances in the equipment
room.
5. Install condensate trap into left-hand side casing hole by
inserting tube connection stubs through casing hole and
rotating until tabs snap into locking position.
6. Fill unused condensate trap casing holes with plastic filler
caps (factory-supplied in loose parts bag).

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 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 condensate trap by splicing to small
diameter tube (factory-supplied in loose parts bag).
