Fig. l 1--Attic Location and Working Platform
The condensate trap MUST be installed below furnace. See
Fig. 5 for dimensions. The drain connection to condensate
trap must also be properly sloped to an open &ain.
NOTE: Combustion-air and vent pipes are restricted to a mira-
mum length of 5 ft. (See Table 7.)
NOTE: A 12-in. minimum offset pipe section is recommended
with short (5 to 8 It) vent systems. This recommendation is to
reduce excessive condensate &oplets from exiting the vent pipe.
(See Fig. 11 or 34.)
Step 5--Horizontal Right (Supply-Air Discharge)
Applications
A horizontal right furnace application is where furnace blower is
located to the left of combustion and controls section of furnace,
and conditioned air is discharged to the right.
CONDENSATE TRAP LOCATION
The condensate trap must be removed from the fMtory-installed
blower shelf location and relocated in selected application location
as shown in Fig. 2 or 12.
To relocate condensate trap fi'om the blower shelf to desired
location, perform the following:
i. 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 (f_actory-supplied in loose parts
bag) into blower shelf hole where trap was removed.
V:I["IAli_'T/7
Local codes may require a drain pan under entire furnace and
condensate trap when a condensing fumace is used in attic
application or over a finished ceiling.
NOTE: In Canada, installations shall be in accordance with
current NSCNGPIC Installation (:odes and.or local codes.
NOTE: The junction box (J-Box) MUST be relocated to opposite
side of furnace casing. (See Fig. 12) See Electrical Connection
section for J-Box relocation.

4. Install condensate trap into left-hand side casing hole by
inserting robe 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
NOTE: See Fig. 12 or tube routing label on main furnace door to
check for proper connections.
i. Collector Box Drain Tube
a. Remove factory-installed plug from LOWER collector box
drain tube (blue and white striped label).
