4.1.2 BGD36 HORIZONTAL INSTALLATION

Do not fill the cavity between the pipe and the framing with any type of material.
Terminals must not be recessed into a wall or siding more than the depth of the return flange 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" thick
but the vent shield must extend the full depth of the
combustible wall.
A. Apply a bead of caulking (not supplied) around the corner edge of
the inside surface of the fi restop assembly, fi t the fi restop
assembly to the hole and secure using the 4 screws W570-0026
(supplied in your manual baggie).
B. Once the vent pipe is installed in its fi nal position, apply high temperature sealant W573-0007 (not
supplied) between the pipe and the fi restop.

4.1.3 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 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" 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" 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. Once the vent pipe is installed in its
final position, apply sealant 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" air space around the
pipe.
