CONDENSATE TRAP
Condensate Trap -- Upflow Orientation
When the furnace is installed in the upflow position, it is not
necessary to relocate the condensate trap or associated tubing.
Refer to Fig. 8 for upflow condensate trap information. Refer to
Condensate Drain section for information how to install the
condensate drain.
Condensate Trap -- Downflow Orientation.
When the furnace is installed in the downflow position, the
condensate trap will be initially located at the upper left corner of
the collector box, as received from the factory. See the top image
in Fig. 9.
When the furnace is installed in the downflow
orientation, the condensate trap must be relocated for proper
condensate drainage. See the bottom image in Fig. 9.
To Relocate the Condensate Trap:
S
Orient the furnace in the downflow position.

Fig. 9 shows the condensate trap and tubing before and after
relocation. Refer to Fig. 9 to begin the trap conversion.
S
Refer to Condensate Drain section for information how to install the
condensate drain.
Condensate Trap -- Horizontal Orientation.
When the furnace is installed in the horizontal right position, the
condensate trap will be initially located at the bottom of the collector
box, as received from the factory. See the top image in Fig. 10.
When the furnace is installed in the horizontal left position, the
condensate trap will be initially located at the top of the collector box,
as received from the factory. See the top image in Fig. 11. In both
cases the trap must be repositioned on the collector box for proper
condensate drainage. See the bottom images in Fig. 10 and 11.
A field--supplied, accessory Horizontal Installation Kit
(trap
grommet) is required for all direct--vent horizontal installations (only).
The kit contains a rubber casing grommet designed to seal between
the furnace casing and the condensate trap. See Fig. 17.
The field--supplied, accessory horizontal drain trap grommet is
ONLY REQUIRED FOR DIRECT VENT APPLICATIONS.
It it
NOT
required for applications using single--pipe or
ventilated combustion air venting.
NOTICE
The condensate trap extends below the side of the casing in
the horizontal position. A minimum of 2--in. (51 mm) of
clearance is required between the casing side and the furnace
platform for the trap to extend out of the casing in the
horizontal position. Allow at least 1/4--in. per foot (20 mm
per meter) of slope down.
NOTICE
To Relocate the Condensate Trap:
S
Remove the knockout in the casing for the condensate trap.
S
Install the grommet in the casing when required for direct--vent
horizontal applications.
S
Orient the furnace in the desired position.
S
Allow for 2 in. (51 mm) of clearance underneath the furnace for the
condensate trap and drain line.
S
Fig. 10 shows the condensate trap and tubing before and after
relocation in the horizontal right position.
S
Fig. 11 shows the condensate trap and tubing before and after
relocation in the horizontal left position.
S
Refer to the appropriate figure to begin the trap conversion.

Refer to Condensate Drain section for information how to install the
condensate drain.
