(Vermont castings Group 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)

2. Attach Inner Starter pipe,
(found in with the logset),
to the next section of inner pipe.
• Run a bead of sealant about 1/2” from the upper
end of the Inner starter pipe and join the two sections
together.
• Drill three pilot holes into the Inner Starter and se-
cure 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 align-
ment 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 using
