1.
Move the fireplace into position. Measure the vent length
required between terminal and fireplace taking into ac-
count the additional length needed for the finished wall
surface and any 1¼" overlaps between venting compo-
nents.
2.
Apply high temperature sealant to the outer edge of
the 4" inner collar of the fireplace. Attach the first vent com-
ponent and secure using 3 self tapping screws. Repeat
using 7" piping.
3.
Holding the air terminal (lettering in an upright, read-
able 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
flange.
A 45° corner installation
can have 0 inch rise
between the fireplace
combustion air collar
and the air terminal.
In
this case, vent lengths
must be kept to a maxi-
mum of 24". For longer
vent lengths, a mini-
mum vertical rise of 24"
is required.

EXTENDED HORIZONTAL AND CORNER
AIR TERMINAL INSTALLATION
For safe and proper operation of the fire-
place, follow the venting instructions exactly.
For optimum performance, it is recommended that hori-
zontal runs have a minimum ¼ inch rise per foot when
using Wolf Steel or Simpson Duravent rigid vent com-
ponents.
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 outer and inner vent pipes. Use Napoleon support ring
assembly
W010-0370
or equivalent noncombustible strap-
ping to maintain the minimum clearance to combustibles
for both vertical and horizontal runs.

5.
Remove nails from the shingles, above and to the
sides of the chimney. Place the flashing over the air termi-
nal and slide it underneath the sides and upper edge of the
shingles. Ensure that the air terminal is properly centred
within the flashing, giving a 3/4" margin all around. Fasten
to the roof. Do
not
nail through the lower portion of the
flashing. Make weather-tight by sealing with caulking. Where
possible, cover the sides and top edges of the flashing
with roofing material.
6.
Apply a heavy bead of weatherproof caulking 2 inches
above the flashing. Slide the storm collar around the air
terminal and down to the caulking. Tighten to ensure that a
weather-tight seal between the air terminal and the collar
is achieved. Attach the other storm collar centred between
the air intake and the air exhaust slots onto the air terminal.
Tighten securely. Attach the vertical rain cap.
Spacers are attached
to the 4" inner flex
liner at predetermined
intervals to maintain
a 1-1/4" air gap to the
7" outer liner. These
spacers must not be
removed.
7.
If more liner needs to be used to reach the fireplace,
couple them together as illustrated. The vent system must be
supported approximately every 3 feet for both vertical and
horizontal runs. Use noncombustible strapping to maintain a
clearance to combustibles of 1".
1.
Install the 4 inch diameter aluminium flexible liner to
the fireplace. Secure with 3 screws and flat washers. Seal
the joint and screw holes using the high temperature seal-
ant provided.
2.
Install the 7 inch diameter aluminium flexible liner to
the fireplace. Attach and seal the joints.
