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.
