(CFM Corporation Vent Components)
1. Install the Restrictor Plate. Consult the ‘Vent Run
Specifications’ on Page 8 to determine whether the
restrictor plate is needed. If so, put the restrictor
plate in place within the inner flue collar as shown in
Figure 16.
5. Install the Outer Adapter Pipe. Apply a 1/4” bead
of cement around the inside wall of the pipe, about
1” from the end. Insert the pipe over the stove flue
collar, keeping the vertical seam oriented to the back
of the stove. Also, be sure to align holes on the pipe
with the holes on the flue collar of the firebox. Fasten
the pipe to the holes in the flue collar with the #12 x
1/2” sheet metal screws provided. (Fig. 19)

end of the Inner starter pipe and join the two sec-
tions together.

secure the assembly with three sheet metal screws.
(Fig. 17)
3. Dry fit the Outer pipe assembly to the stove for the
purpose of determining the center line of the pipe on
the wall.
• Side Wall Terminations: Dry fit the outer elbow
with the vertical outer vent and confirm the centerline
alignment with the wall thimble opening.
Remove the pipes and elbows before continuing with
Step 4.
4. Attach the Inner Vent Assembly to the stove.
• Run a bead of sealant around the bottom end of
the starter pipe and attach the assembly to the stove
