Fig. 24 Assemble the wall sleeve and firestop.
Attach the firestop plate to the sleeve end with the
holes. (Fig. 24) NOTE: The wall sleeve is required
in combustible walls only.
3. Install the Wall Firestop/Sleeve assembly into the
wall cutout and fasten the firestop to the wall cutout
framing members. (Fig. 24)
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. 27)

4. If necessary, measure to determine the vertical
length (X) of pipe required from the first (transition)
elbow to the wall cutout centerline, including a 2”
overlap at the joint. (Fig. 25) 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. Install the elbow using 3 sheet metal screws at each
joint.
7. Measure, and cut if necessary, the appropriate
length of pipe section needed to make the connec-
tion 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.
