HORIZONTAL RIGHT (SUPPLY-AIR DISCHARGE)
APPLICATIONS
In a horizontal right furnace application, the blower is located to
the left of the burner section, and conditioned air is discharged to
the right.
CAUTION:
MINOR PROPERTY DAMAGE
Failure to follow this caution may result in minor
property damage.
Local codes may require a drain pan under entire furnace
and condensate trap when a condensing furnace is used in
attic application or over a finished ceiling.
NOTE:
In Canada, installations shall be in accordance with
current NSCNGPIC Installation Codes and/or local codes.
NOTE:
The auxiliary junction box (J-Box) MUST be relocated to
opposite side of furnace casing. (See Fig. 12.) See Electrical
Connection section for J-Box relocation.
A.
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 12.
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. Install casing hole filler cap (factory-supplied in loose parts
bag) into blower shelf hole where trap was removed.
WARNING:
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 com-
bustion products being drawn in from appliances in the
equipment room.
4. Install condensate trap into right-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).

See Fig. 12 or tube routing label on main furnace door to
check for proper connections.
1. Collector Box Drain Tube:
a. Remove factory-installed plug from LOWER collector
box drain tube (blue and white striped label).
b. Install removed clamp and plug into UPPER collector
box drain tube (blue label) which was previously con-
