4.2.3 APPLIANCE VENT CONNECTION
Install the inner fl ex pipe to the appliance. Secure with 3 screws
A.
and fl at washers. Seal the joint and screw holes using the high
temperature sealant W573-0007 (not supplied).
Install the outer fl ex pipe to the appliance. Attach and seal
B.
the joints using the high temperature sealant W573-0002 (not
supplied).
4.3
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.
4.3.1 HORIZONTAL AIR TERMINAL INSTALLATION
Move the fi replace into position. Measure the vent length
A.
required between terminal and fi replace taking into
account the additional length needed for the fi nished
wall surface and any 1¼" overlaps between venting
components.
Apply high temperature sealant W573-0007 (not
B.
supplied) to the outer edge of the inner collar of the
fi replace. Attach the fi rst inner rigid pipe component
and secure using 3 self tapping screws. Repeat using the
outer rigid pipe.
Insert the vent pipes through the fi restop maintaining the required clearance to combustibles. Holding
C.
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 its return fl ange.
4.3.2 EXTENDED HORIZONTAL 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.
