Accessories
The components in Figure 14 & Figure 15 are included in
the extra parts bag supplied with the purchase of J952V*U
furnaces. Depending on your particular installation, some
of these components are optional and may not be used.
Please refer to the descriptions and accompanying figures
when installing these items.
Finish Flange
The finish flange 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 finish flange, gasket, and cabinet are aligned.
1. Position flange gasket over hole in the furnace cabinet.
2. Position finish flange on top of the flange gasket.
NOTE: Make sure the flange is properly oriented so that
the FRONT lettering is located near the front of the furnace
as shown in
Figure 14.
3. Secure flange and gasket to cabinet with three field 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 14.
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 Components
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.
• The 2” PVC pipe shown in
Figure 15 is not provided in
the extra parts bag.
The 2” PVC Tee and Trap are used when the inducer is
rotated to vent out thru the left or right side of the furnace
cabinet. See
Figure 15.
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 26 (page 27) for hole location. The
condensate drain should be connected to the barbed end.
Attach 1” PVC drain line to the threaded end.
Typical Orientation
1. Install the PVC Tee vertically on the 2” vent pipe that is
extending out the side of the cabinet. Permanently bond
them together using appropriate primer and cement. Refer
to the typical orientation shown in
Figure 15.
2. Install the reducer or PVC trap (if supplied) on the bottom
end of the PVC Tee. Permanently bond them together
using appropriate primer and cement.
