4. For CFM Vent Pipe only: If necessary, measure
to determine the vertical length (X) of pipe required
from the adapter pipe to the wall cutout centerline,
including a 2” overlap at the joint. (Fig. 26) use a
hacksaw or tin snips to trim the pipe as needed.

sleeve. Seal the joint inside the wall plate if needed
to keep cold air from being drawn into the home.
9. 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. 28)
10. For both CFM and DuraVent Systems: Install the
vent terminal. (Fig. 29) Apply high temperature seal-
ant one inch from the ends of the inner and outer
collars. Guide the inner and outer vent termination
collars into the adjacent pipes. Double check that
the vent pipes overlap the collars by 2”. Fasten the
termination to the wall with the screws provided, and
caulk the joint with weatherproof sealant.

section(s), trimmed end down, to the point of the el-
bow. Drill 3 holes through each joint and fasten with
sheet metal screws.
6. 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 dis-
tance required if installing a second 90° elbow. (Fig.
