horizontal installation

WARNING
!
• The fi restop 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 fl ange of the mounting
plate.
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.

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 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.
