Accessories
The components in Figures 17 - 19 are included in the extra
parts bag supplied with the purchase of *TC/*TLfurnaces.
Depending on your particular installation, some of these
components are optional and may not be used. Please
refer to the descriptions and accompanying fi gures when
installing these items.
Finish Flange
The fi nish fl ange must be installed to vent the combustion
air pipe through the top of the furnace.
NOTE: For proper
installation it is important that the pipe and screw holes
in the fi nish fl ange, gasket, and cabinet are aligned. See
Figure 17.
1. Position fl ange gasket over hole in the furnace cabinet.
2. Position fi nish fl ange on top of the fl ange gasket.
3. Secure fl ange and gasket to cabinet with three fi eld
supplied sheet metal screws.
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.
PVC TEE, Reducer, & Hose Barbs
The 2” PVC tee, reducer, and hose barb are used when
the inducer is rotated to vent out thru the left or right side
of the furnace cabinet. See Figure 19.
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
end inserted 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-fi t them fi rst to ensure
proper fi t and alignment with other vent pipes.
• The 2” PVC pipe shown in Figure 19 is not provided
in the extra parts bag.
1. Install the 1/2” x 1/2” hose barb on the 2” PVC reducer.
Do not over tighten! NOTE: Use an adequate amount of
Tefl on 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.
4. Verify all connections and joints for tight fi t and proper
alignment with other vent pipes.
