4.1 HORIZONTAL INSTALLATION
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.
NOTE: Do not fi ll the air space between the fi restop
spacer and the exterior wall with any type of insulating
material (i.e., spray foam).
A. Assemble the shield to the spacer as shown, using the 3
shorter screws supplied.
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 the 4 longer screws supplied. Once the vent pipe is installed in its fi nal
position, apply sealant between the pipe and the fi restop spacer.
4.2 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.
