5.3 USING RIGID VENT COMPONENTS
The vent system must be supported approximately every 3 feet (0.9m) 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.

5.3.1 HORIZONTAL AIR TERMINAL INSTALLATION
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” (31.8mm) overlaps between
venting components.
B.
Apply high temperature sealant W573-0007 (not
supplied) to the outer edge of the inner exhaust
fl
ue
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.

WARNING
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
MAINTAIN CLEARANCES TO COMBUSTIBLES.
5.3.2 EXTENDED HORIZONTAL AND CORNER TERMINAL INSTALLATION
A 45° corner installation can have 0” (0mm) rise between the appliance
combustion air collar and the air terminal. In this case, vent lengths must be
kept to a maximum of 24” (609.6mm) . For longer vent lengths, a minimum
vertical rise of 24” (609.6mm) is required.
A.
Follow the instructions for "HORIZONTAL AIR TERMINAL
INSTALLATION" section.
B.
Continue adding components alternating inner and outer vent pipes. Ensure that
all inner vent pipes and elbows have sufficient vent spacers attached and each
component is securely fastened to the one prior. Attach the telescopic sleeve to the
vent run. Secure and seal. To facilitate completion, attach inner and outer couplers to
the air terminal.
C.
Install the air terminal. See “HORIZONTAL AIR TERMINAL INSTALLATION” section. Extend the outer
telescopic sleeve; connect to the air terminal assembly. Fasten with self tapping screws and seal.
