15. Remove the cap on the cap on the top side of the
cold header and move it to the bottom position on
the cold header.
16. Slide PVC through vent outlet adaptor and insert
into inducer outlet.
17. Twist to insure PVC is fully inserted.
18. Tighten the two clamps.
19. Install the combustion air inlet PVC pipe.
NNoottee:: The vent outlet adapter is used for strain relief
against the weight of the venting. The clamp
should be tightened after the internal connection
is made.
NNoottee:: If required, transition to larger venting within 2'
of the cabinet. An 2" x 3" offset coupling is
required if the transition is made in a horizontal
plane. Use coupling CPL01544 (Canadian
applications may use BAYREDUCE to meet ULC-
S636 requirements.) See Horizontal Venting
section for proper orientation of 2” x 3” offset
coupling.
Condensate Trap Installation
20. Reinstall the condensate adapter if it was earlier
removed or ensure adapter is still in place.
IImmppoorrttaanntt:: The condensate adapter must be present
for proper condensate drain operation.
21. Install condensate trap into new location by fitting
into grommet and aligning the hole on the
condensate trap with the hole labeled “HL”.
When installing a 21.0” wide S-Series furnace, the
condenser trap grommet must be rotated so that the
notch in the grommet faces the outer edge of the
furnace cabinet as shown in the illustrations below and
to the top left in next page. This allows the rain gutter
tubing to fully seat onto the lower condensate port
trap.
22. Hand tighten screw with a 1/4” nut driver. Do not
over torque or use a drill gun.
