NOTE:
Failure to use CPVC elbows may allow drain to kink and
prevent 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.
CONDENSATE TRAP LOCATION (ALTERNATE UPFLOW
ORIENTATION)
An alternate location for the condensate trap is the left-hand side
of casing. (See Fig. 2 and 7.)
NOTE:
If the alternate left-hand side of casing location is used,
the factory-connected drain and relief port tubes must be discon-
nected and modified for attachment. See Condensate Trap Tubing
(Alternate Upflow Orientation) section for tubing attachment. To
relocate condensate trap to the left-hand side, perform the follow-
ing:
1. Remove 3 tubes connected to condensate trap.
2. Remove trap from blower shelf by gently pushing tabs inward
and rotating trap.
3. 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.
4. 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.
5. Fill unused condensate trap casing holes with plastic filler
caps (factory-supplied in loose parts bag).
CONDENSATE TRAP TUBING (ALTERNATE UPFLOW
ORIENTATION)
NOTE:
See Fig. 7 or tube routing label on main furnace door to
confirm location of these tubes.
1. Collector Box Drain Tube
Connect collector box drain tube (blue label) to condensate
trap.
NOTE:
On 17-1/2 in. wide furnaces ONLY, cut tube between
corrugated sections to prevent kinks from occurring.
