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 Figure 8. When the furnace is installed in the
downflow orientation, the condensate trap must be relocated
for proper condensate drainage. See bottom image in Figure 8.
To Relocate the Condensate Trap:
 Orient the furnace in the downflow position.
 Figure 8 shows the condensate trap and tubing before and
after relocation. Refer to Figure 8 to begin the trap conversion.
 Refer to Condensate Drain section for information how to install
the condensate drain.
