Fig. 11 -- Horizontal Left Tube Configuration
b. Remove and discard UPPER (molded) inducer housing
drain tube which was previously connected to
condensate trap.
c. Install cap and clamp on UPPER inducer housing drain
connection where molded drain tube was removed.
d. Use inducer housing drain tube (violet label and
factory--supplied in loose parts bag) to connect LOWER
inducer housing drain connection to the condensate trap.
e. Connect inducer housing drain connection to
condensate trap.
(1.) Condensate Trap Located on Left Side of Casing
a. Determine appropriate length and cut.
b. connect tube to condensate trap.
c. Clamp tube to prevent any condensate leakage.
(2.) Condensate Trap Located on Right Side of Casing
a. Route inducer housing drain tube (violet label)
directly from inducer housing to condensate trap.
b. Determine appropriate length and cut.
c. Connect tube to condensate trap.
d. Clamp tube to prevent any condensate leakage.
3. Relief Port Tube
Refer to Pressure Switch Tubing section for connection
procedure.
Condensate Trap Field Drain Attachment
Refer to Condensate Drain section for recommendations and
procedures.
Pressure Switch Tubing
One collector box pressure tube (pink label) is factory connected to
the pressure switch for use when furnace is installed in UPFLOW
or HORIZONTAL LEFT applications.
The tube MUST be
disconnected and used or the condensate trap relief port tube. The
other collector box pressure tube (green label) which was factory
connected to the condensate trap relief port connection MUST be
connected to the pressure switch in DOWNFLOW or
HORIZONTAL RIGHT applications.
NOTE: See Fig. 9 or 10 or tube routing label on man furnace door
to check for proper connections.
Relocate tubes as described below.
1. Disconnect collector box pressure tube (pink label) attached
to pressure switch.
2. Extend collector box pressure tube (green label) which was
previously connected to condensate trap relief port
connection
by
splicing
to
small
diameter
tube
(factory--supplied in loose parts bag).
3. Connect collector box pressure tube (green label) to
pressure switch connection labeled COLLECTOR BOX.
4. Extend collector box pressure tube (pink label) which was
previously connected to pressure switch by splicing to
remaining small diameter tube (factory--supplied in loose
parts bag).
5. Route this extended tube (pink label) to condensate trap
relief port connection.
6. Determine appropriate length, cut, and connect tube.
7. Clamp tube to relief port connection.
Condensate Trap Freeze Protection
Refer to Condensate Drain Protection section for recommendations
and procedures.
HORIZONTAL LEFT (SUPPLY--AIR
DISCHARGE) APPLICATIONS
A horizontal left furnace application is where furnace blower is
located to the right of combustion and controls section of furnace,
and conditioned air is discharged to the left.
