WALL AND CEILING PROTECTION

This application occurs when venting through an exterior wall. Having determined the air terminal location, cut and frame a hole in an exterior wall with a minimum square opening of 8” wide x 8” high.

1.Apply a bead of caulking all around and place the ﬁrestop spacer over the framework to restrict cold air from being drawn into the room or around the ﬁreplace. Ensure that the spacer maintains the required clearance to combustibles. Secure the spacer in place using the 4 longer screws supplied. Once the vent pipe is installed in its ﬁnal position, apply high temperature sealant (not supplied) between the pipe and the ﬁrestop spacer.

1.Determine the air terminal location, cut and frame a 8” square opening in the ceiling and the roof to provide the minimum clearance between the vent pipe and any combustible material. Try to center the vent pipe location midway between two joists to prevent having to cut them. Use a plumb bob to line up the center of the openings.

Do not ﬁll this space with any type of material.

		A vent pipe shield will prevent any materials such as
8”	8”	insulation, from ﬁlling up the 1" air space around the
8”	8”	pipe. Nail headers between the joist for extra support.

2. Apply a bead of caulking (not supplied) to the framework or to the Wolf Steel vent pipe shield plate or equivalent (in the case of a ﬁnished ceiling), and secure over the opening in the ceiling. A ﬁrestop must be placed on the bottom of each framed opening in a roof or ceiling

that the venting system passes through. Apply a bead of caulking all around and place a ﬁrestop spacer over the vent shield to restrict cold air from being drawn into the room or around the ﬁreplace. Ensure that both spacer and shield maintain the required clearance to combustibles. Once the vent pipe is installed in its ﬁnal position, apply sealant between the pipe and the ﬁrestop assembly.

3.In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any materials, such as insulation, from ﬁlling up the 1" air space around the pipe.
