a. Extend collector box tube (green label) which was
previously connected to the 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 the condensate trap.
c. Determine appropriate length, cut, and connect tube.
d. Clamp tube to prevent any condensate leakage.
CONDENSATE TRAP FIELD DRAIN
ATTACHMENTS
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 High Pressure Switch for use when furnace is
installed in UPFLOW applications. This tube MUST be
disconnected, extended, rerouted, and then reconnected to the
pressure switch in HORIZONTAL LEFT applications for 060 and
080 heating input furnaces.
NOTE: See Fig. 10 or tube routing label on main furnace door to
check for proper connections.
Modify tube as described below:
1. Disconnect collector box pressure tube (pink label)
attached to High Pressure Switch.
2. Use smaller diameter tube (factory-supplied in loose parts
bag) to extend tube disconnected in item 1.
3. Route extended tube:
a. Behind inducer housing.
b. Between blower shelf and inducer housing.

CONDENSATE TRAP FREEZE PROTECTION
Refer to Condensate Drain
recommendations and procedures.
CONSTRUCT A WORKING PLATFORM
Construct working platform where all required furnace clearances
are met. (See Fig. 3 and 11 or 12.)
CAUTION
!
UNIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent
unit operation.
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 drain.
NOTE: Combustion-air and vent pipes are restricted to a
minimum length of 5 ft. (2 M)(See Table 13.)
NOTE: A 12-in. (305 mm) minimum offset pipe section is
recommended with short (5 to 8 ft or 2 to 3 M)) vent systems.
This recommendation is to reduce excessive condensate droplets
from exiting the vent pipe. (See Fig. 11, 12 or 43.)
Step 5 - - 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.
