horizontal installation
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 firestop assembly. Dry
fit the firestop assembly before proceeding to ensure the
brackets on the rear surface fit to the inside surface of the
horizontal framing.
The vent shield must be installed to the full depth of the
combustible wall. The length of the vent shield may cut
shorter for combustible walls that less than

A. Apply a bead of caulking (not supplied) around the
corner edge of the inside surface of the firestop
assembly, fit the firestop assembly to the hole and
secure using 4 screws.
B. Once the vent pipe is installed in its final position, apply red RTV silicone (W573-0002) (not supplied)
between the pipe and the firestop.
vertical installation
This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor.
See the “accessories” section to order specific 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 filling 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 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.

silicone (W573-0002) (not supplied) between the pipe and the firestop
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 filling up the 1" (25mm) air space around the pipe.

• 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 return flange of the mounting
plate.
The above is for illustration purposes only. Vents do
not always pass through center of frame.
