4.1.1 HORIZONTAL INSTALLATION

EN
THE FIRESTOP ASSEMBLY MUST BE INSTALLED WITH THE VENT SHIELD TO THE TOP.
TERMINALS MUST NOT BE RECESSED INTO A WALL OR SIDING MORE THAN THE DEPTH OF THE
This application occurs when venting through an exterior wall.
Having determined the correct height for the air terminal location, cut
and frame a hole in the exterior wall as illustrated to accommodate
the fi restop assembly. Dry fi t the fi restop assembly before
proceeding to ensure the brackets on the rear surface fi t to
the inside surface of the horizontal framing.
The length of the vent shield may be cut shorter
for combustible walls that are less than 8 1/2"
(215.9mm) thick but the vent shield must extend the
full depth of the combustible wall.
A. Assemble the shield to the spacer as
shown, using 3 screws.
B. Place the fi restop top so that the vent shield
covers the top of the vent within the opening.
Ensure that both spacer and shield maintain the required
clearance to combustibles.
C. Secure the spacer in place using 4 screws. Once the
vent pipe is installed in its fi nal position, apply sealant
between the pipe and the fi restop spacer.

4.1.2 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
Mill Pac sealant (W573-0007) (not supplied) or red RTV silicone (W573-0002) (not
supplied) 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.
