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).
b. Route extended collector box pressure tube to relief port
connection on condensate trap.
c. Determine appropriate length, cut, and connect tube.
d. Clamp tube to prevent any condensate leakage.
CONDENSATE TRAP FIELD DRAIN ATTACHMENT
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 and should not require any
modification.
NOTE: See Fig. 9 or tube routing label on main furnace door to
check for proper connections.
CONDENSATE TRAP FREEZE PROTECTION
Refer to Condensate Drain Protection section for recommenda-
tions and procedures.
CONSTRUCT A WORKING PLATFORM
Construct working platform where all required furnace clearances
are met. (See Fig. 3 and 10.)

The condensate trap MUST be installed below furnace. See
Fig. 4 for dimensions. The drain connection to condensate
trap must also be properly sloped to an open drain.
NOTE: Combustion-air and vent pipes are restricted to a mini-
mum length of 5 ft. (See Table 6.)
→
NOTE: A 12-in. minimum offset pipe section is recommended
with short (5 to 8 ft) vent systems. This recommendation is to
reduce excessive condensate droplets from exiting the vent pipe.
(See Fig. 10 or 32.)
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.
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.
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:
