To Relocate the Condensate Trap:

S Orient the furnace in the downflow position.

S Fig. 9 shows the condensate trap and tubing before and after

relocation. Refer to Fig. 9 to begin the trap conversion.

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

The kit contains a rubber casing grommet designed to seal between

the furnace casing and the condensate trap. See Fig. 18.

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.
