plate to wall.
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.

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.
27)
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. 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)
