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:
• Orient the fllmace 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.
• Refer to Condensate Drain section for infomaation how to install the
condensate drain.
Condensate
Trap - Horizontal
Orientation.
When the fl_mace 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 fl_mace 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 inaage 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 robber casing grommet designed to seal between
the fllmace casing and the condensate trap. See Fig. 16.
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.
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.
To Relocate the Condensate
Trap:
• Remove the knockout in the casing for the condensate trap.
• Install the grommet in the casing when required for direct-vent
horizontal applications.
• Orient the fl_mace in the desired position.
• Allow for 2 in. (51 mm) of clearance underneath the fl_mace for the
condensate trap and drain line.
• Fig. 10 shows the condensate trap and tubing before and after
relocation in the horizontal right position.
• Fig. 11 shows the condensate trap and tubing before and after
relocation in the horizontal left position.
• Refer to the appropriate figure to begin the trap conversion.
• Refer to Condensate Drain section for infom_ation how to install the
condensate drain.
