The vent system must be supported approximately every 3
feet for both vertical and horizontal runs. Use Wolf Steel vent
spacers or equivalent every 3 feet and either side of each
elbow to maintain the minimum ¼” clearance between the
outer and inner vent pipes. Use Wolf Steel support ring as-
sembly 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 joists
may be sealed using either red rTv high temp
silicone sealant or Black high temp mill Pac with
the exception of the fireplace exhaust flue collar
which must be sealed using mill Pac (not supplied).
1. Move the fire-
place into position.
Measure the vent
length required
between terminal
and fireplace tak-
ing into account

length needed for
the finished wall
surface and any
¼” overlaps between venting components.
2. Apply high temperature sealant (W573-0007 not pro-
vided) to the outer edge of the 4” inner collar of the fireplace.
Attach the first vent component and secure using 3 self
tapping screws. Repeat using 7” piping.
3. Holding the air terminal (with the air deflectors to the
top and the lettering in an upright, readable position) insert
the terminal into both vent pipes with a twisting motion to
ensure that both the terminal sleeves engage into the vent
pipes and sealant. Secure the terminal to the exterior wall and
make weather tight by sealing with caulking (not supplied).
1. Install the 4” diameter aluminium flexible liner to the
fireplace. Secure with 3 screws and flat washers. Seal the

the one prior. Attach the 4”
telescopic sleeve to the vent
run.
Repeat using a 7” telescopic sleeve. Secure and seal as
before. To facilitate completion, attach 4” and 7” couplers to
the air terminal.
