USING RIGID VENT COMPONENTS

The vent system must be supported approximately every 3
feet for both vertical and horizontal runs. Use Wolf Steel vent
spacers W615-0033 every 3 feet on either side of each elbow
to maintain the minimum 1¼" clearance between the 7" rigid
vent pipe and 4" rigid vent pipes. Use Napoleon® support ring
assembly W010-0370 or equivalent noncombustible strapping
to maintain the minimum clearance to combustibles for both
vertical and horizontal runs.
1. Move the fi replace into position. Measure the vent length 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.
2. Apply high temperature sealant W573-0007 (not supplied) to the outer edge of the 4" inner collar of the fi replace. Attach
the fi rst 4" rigid vent pipe component and secure using 3 self tapping screws. Repeat using the 7" rigid vent pipe.
3. Holding the air terminal (lettering in an upright, readable position), insert into both vent pipes with a twisting motion to
ensure that both the terminal sleeves engage into the vent pipes and the sealant. Secure the terminal 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 by 1½", the depth of the return
fl ange.
EXTENDED HORIZONTAL AND CORNER AIR TERMINAL INSTALLATION
A 45° corner installation can have 0" rise between the fi replace combustion air collar and the air terminal. In this case,
vent lengths must be kept to a maximum of 24". For longer vent lengths, a minimum vertical rise of 24" is required.
1. Follow the instructions for "Horizontal Air Terminal Installations".
2. Continue adding components alternating 4" rigid vent pipe and 7" rigid vent pipe. Ensure
that all 4" rigid vent pipe and elbows have suffi cient vent spacers attached and each component
is sealed and securely fastened to the one prior. Attach the 4" telescopic sleeve to the vent
run. Repeat using a 7" telescopic sleeve. Seal and secure as before. To facilitate completion,
attach 4" and 7" couplers to the air terminal.
3. Install the air terminal. See item 3, Horizontal Air Terminal Installation. Extend the 4"
telescopic sleeve; apply sealant and connect to the air terminal assembly. Fasten with self
tapping screws. Repeat using the 7" telescopic sleeve.

1. Install the 4" fl ex vent pipe to the fi replace. Secure with 3
screws and fl at washers. Seal the joint and screw holes using
the high temperature sealant W573-0007 (not supplied).
2. Install the 7" fl ex vent pipe to the fi replace. Attach and
seal the joints using the high temperature sealant W573-0002
(not supplied).
