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
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
furnace is installed in the downflow orientation, the condensate trap
must be relocated for proper condensate drainage. See the bottom image
in Fig. 8.
To Relocate the Condensate Trap:
• Orient the furnace in the downflow position.
• Fig. 8 shows the condensate trap and tubing before and after
relocation. Refer to Fig. 8 To begin the trap conversion.
• Refer to Condensate Drain section for information how to install the
condensate drain.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
