1.
Remove inner blower door.
2.
Remove access panels.
3.
Loosen hose clamps that attach rubber fittings to the
white PVC pipes inside the vestibule area. See Figure
13.
4.
Loosen the clamp that secures the pipes at the blower
deck. See Figure 13.
5.
Remove white PVC pipes, slide up and out through
the top cap.
6.
Remove the black plastic fitting in top cap, which
previously aligned the PVC pipes.
7.
Remove the sheet metal patch plate on the side of
the cabinet that covers the openings for side venting
option. Save screws for reuse.
8.
Re-use the patch plate to cover the hole in the top cap.
See Figure 15. Remove the 2 screws that secure the
top cap to the furnace on the right side and re-install,
securing the right edge of the patch plate and the right
side of the top cap to the furnace. Use 2 self-drilling
sheet metal screws (provided) to finish securing the
left edge of the patch plate on the left side.

9.
Use a utility knife to cut out the cabinet insulation for
the right side vent / air intake.
10. Install the two 90° street elbows (provided) through
the side of the cabinet. The male side of each elbow
should extend down through the blower deck and
connect to the rubber fittings below. Once the elbows
are properly positioned, tighten each clamp.
11. Peel protective backing from side vent sealing gaskets
(2) and apply to side vent sealing plates (2) as shown
in Figure 14.
12. Install the side vent sealing plates and gaskets on
the exterior of the cabinet as shown in Figure 14.
Secure with six mounting screws (four reused and two

13. Install sheet metal screws (provided) to seal extra two
holes in cabinet not used with side vent clamps.
Joint Cementing Procedure
All cementing of joints should be done according to the
specifications outlined in ASTM D2855.
DANGER OF EXPLOSION!
Fumes from PVC glue may ignite during system check.
Allow fumes to dissipate for at least 5 minutes before
placing unit into operation.
1.
Measure and cut vent pipe to desired length.
2.
Debur and chamfer end of pipe, removing any ridges
or rough edges. If end is not chamfered, edge of pipe
may remove cement from fitting socket and result in a
leaking joint.
3.
Clean and dry surfaces to be joined.
4.
Test fit joint and mark depth of fitting on outside of pipe.
5.
Uniformly apply a liberal coat of PVC primer for PVC
or use a clean dry cloth for ABS to clean inside socket
surface of fitting and male end of pipe to depth of fitting
socket.
6.
Promptly apply solvent cement to end of pipe and
inside socket surface of fitting. Cement should be
applied lightly but uniformly to inside of socket. Take
care to keep excess cement out of socket. Apply
second coat to end of pipe.
NOTE: Time is critical at this stage. Do not allow primer
to dry before applying cement.
7.
Immediately after applying last coat of cement to pipe,
and while both inside socket surface and end of pipe
are wet with cement, forcefully insert end of pipe into
socket until it bottoms out. Turn PVC pipe 1/4 turn
during assembly (but not after pipe is fully inserted) to
distribute cement evenly. DO NOT turn ABS or cellular
core pipe.
NOTE: Assembly should be completed within 20
seconds after last application of cement. Hammer
blows should not be used when inserting pipe.
8.
After assembly, wipe excess cement from pipe at end
of fitting socket. A properly made joint will show a bead
around its entire perimeter. Any gaps may indicate a
defective assembly due to insufficient solvent.
9.
Handle joints carefully until completely set.
