For DuraVent pipe only: Install vent pipe by aligning the
locking system together, sliding the pipes together and
twisting clockwise.
• Install 90° elbow. Twist lock as before.
• Slide the wall plate over horizontal run before attach-
ing the horizontal run to the elbow. Fasten wall plate to
wall.
4. For Vermont Castings Group Vent Pipe only: If nec-
essary, measure to determine the vertical length (X) of
pipe required from the adapter pipe to the wall cutout
centerline, including a 2" (51mm) overlap at the joint.
(Fig. 24) use a hacksaw or tin snips to trim the pipe as
needed.
Fig. 24 Determine the vertical pipe length.
5. Install first the inner then the outer straight pipe

measure vertical vent

6. Seal and install the elbow using 3 sheet metal screws
at each joint.
7. Measure, and cut if needed, the appropriate length of
pipe section needed to make the connection through
the wall. Include a 2" overlap; i.e. from the elbow to
the outside wall face, about 2" or the distance required
if installing a second 90° elbow. (Fig. 25)
8. Slip the wall plate and trim collar over the interior end
of the horizontal pipe and install into the wall sleeve.
Seal the joint inside the wall plate if needed to keep
cold air from being drawn into the home.
9. Seal the ends and connect the horizontal pipe to the
elbow. Fasten the wall plate to the pipe with three
sheet metal screws. Slide the trim collar up against
the wall plate to cover the screws. (Fig. 26)
