3. Measure the wall thickness and cut the wall sleeve
sections to proper length (MAXIMUM 12”). Assemble
the sleeve with the #8 sheet metal screws supplied.
Attach the firestop plate to the sleeve end with the
holes. (Fig. 25) NOTE: The wall sleeve is required in
combustible walls only.
4. Install the Wall Firestop/Sleeve assembly into the
wall cutout and fasten the firestop to the wall cutout
framing members. (Figs. 18, 19)
5. Measure, and cut if necessary, the appropriate
length of pipe section needed to make the connec-
tion through the wall.
6. 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.
7. Connect the pipe to the inner collar. 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. (Figs. 18, 19)
8. Install the vent terminal. (Figs. 18, 19) 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.
