5.2.2 VERTICAL INSTALLATION
This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor.
See accessories to order specifi c kits required.
A. Determine the air terminal location, cut and frame a square opening as
illustrated in the ceiling and the roof to provide the minimum 1" (25mm)
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. A vent pipe shield will prevent any materials such as
insulation, from fi lling up the 1" (25mm) air space around the pipe.
Nail headers between the joist for extra support.
B. 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 fi nished ceiling), and secure
over the opening in the ceiling. A fi restop 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 fi restop spacer over the vent
shield to restrict cold air from being drawn into the room or around the fi replace. Ensure
that both spacer and shield maintain the required clearance to combustibles. Once the
vent pipe is installed in its fi nal position, apply sealant between the pipe and the fi restop
assembly.
C. 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 fi lling up the 1" (25mm)
air space around the pipe.
