3.3

USING RIGID VENT COMPONENTS

The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use Wolf
Steel Ltd. support ring assembly or equivalent noncombustible strapping to maintain the minimum clearance to
combustibles for both vertical and horizontal runs.
All inner exhaust and outer intake vent pipe joints may be sealed using either red high temperature silicone
sealant W573-0002 (not supplied) or black high temperature sealant W573-0007 Mill Pac (not supplied) with
the exception of the appliance exhaust fl ue collar which must be sealed using Mill Pac.

3.3.1 HORIZONTAL AIR TERMINAL INSTALLATION

RISK OF FIRE, DO NOT ALLOW LOOSE MATERIALS OR INSULATION TO TOUCH THE VENT PIPE.
REMOVE INSULATION TO ALLOW FOR THE INSTALLATION OF THE ATTIC SHIELD AND TO
A. Move the appliance into position.
Measure the vent length required
between terminal and appliance
taking into account the additional
length needed for the fi nished
wall surface and any 1¼" overlaps
between venting components.
B. Apply high temperature sealant W573-
0007 (not supplied) to the outer edge of the
inner collar of the appliance. Attach the fi rst
inner rigid pipe component and secure using 3 self
tapping screws. Repeat using the outer rigid pipe.
C. Insert the vent pipes through the fi restop maintaining the required
clearance to combustibles. Holding the air terminal (lettering in an upright,
readable position), secure to the exterior wall and make weather tight by sealing with caulking (not
supplied).
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the
depth of the return fl ange.

3.3.2 EXTENDED HORIZONTAL AND CORNER AIR TERMINAL INSTALLATION

A. Follow the instructions for "HORIZONTAL AIR TERMINAL INSTALLATIONS" section.
Continue adding components alternating inner rigid pipe and outer rigid pipe. Ensure
B.
that all inner rigid pipe and elbows have sufficient vent spacers attached and each
component is sealed and securely fastened to the one prior. Attach the inner telescopic
sleeve to the vent run. Repeat using the outer telescopic sleeve. Seal and secure as
before. To facilitate completion, attach inner and outer couplers to the air terminal.
C. Install the air terminal. See "HORIZONTAL AIR TERMINAL INSTALLATION" section.
