Rubber Grommets
The 2 1/4" rubber grommet is used to seal the opening
between the furnace cabinet and the 2" PVC vent pipe.
The rubber grommet should be installed in the 3" hole
prior to running the vent pipe out of cabinet. No sealants
are required. See Figure 18.
The 7/8" rubber grommet is used to seal the opening
between the furnace cabinet and the gas pipe. The rubber
grommet should be installed in the 1 5/8" hole prior to
running the gas pipe into the cabinet. No sealants are
required.
The 3/4" rubber grommet is used if venting out the left
side of the cabinet and the drain tube is routed through
the blower deck. Remove the plastic plug from the hole
and install the grommet before routing the drain tube.

The 1/2" x 3/4" hose barb can be used to route the
condensate drain to the outside of the cabinet. It must
be installed from inside the cabinet with the threaded

thru the 1 1/16" hole. See Figure 29
(page 33) for hole location The condensate drain should
be connected to the barbed end. Attach 1" PVC drain line
to the threaded end.
IMPORTANT NOTES:
= Before
permanently
installing these components,
it is recommended
you dry-fit them first to ensure
proper fit and alignment
with other vent pipes.

Teflon tape on the threads. Do not use liquid sealants.
2. Install the reducer on one end of the PVC tee. Use
appropriate primer and cement to permanently bond
the reducer and tee together.
3. Install the tee on the 2" vent pipe that is extending out
the side of the cabinet. Use appropriate primer and
cement to permanently bond them together.
