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
UNDERSIDE OF FIRESTOP
openings. A vent pipe shield will prevent any materials such as
JOIST
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
SHIELD
system passes through. Apply a bead of caulking all around and place a
VENT
fi restop spacer
over the vent shield to restrict cold air from being drawn into the

clearance to
combustibles. Once the vent pipe is installed in its fi nal position, apply
Mill Pac sealant (W573-0007) (not supplied) or red RTV silicone (W573-0002) (not
VENT
supplied) between the pipe and the fi restop assembly.
