-
taching the horizontal run to the elbow. Fasten wall
plate to wall.
4. For CFM Vent Pipe only: If necessary, measure
to determine the vertical length (X) of pipe required

including a 2” (51mm) overlap at the joint. (Fig.
24) use a hacksaw or tin snips to trim the pipe as
needed.

5. Install first the inner then the outer straight pipe
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. 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 dis-
tance 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)

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.

(#7FSDRG) or Polished Brass Pipe Rings (#7FS-
