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 1¼" clearance be-
tween the outer and inner vent pipes. Use Wolf Steel sup-
port ring assembly or equivalent noncombustible strap-
ping to maintain the minimum clearance to combustibles
for both vertical and horizontal runs.
HORIZONTAL AIR TERMINAL INSTAL-
LATION
1.
Move the fireplace into po-
sition. Measure the vent length
required between terminal and
fireplace taking into account the
additional length needed for the finished wall surface and any
1¼" overlaps between venting components.
2.
Apply high temperature sealant to the outer edge of the 5"
inner collar of the fireplace. Attach the first vent component and
secure using 3 self tapping screws. Repeat using 8" piping.
3.
Holding the air terminal (with the air deflectors to the
top), insert 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).
The air terminal mounting plate may be recessed into the
exterior wall or siding by 1½", the depth of the return flange.
EXTENDED HORIZONTAL AIR TERMI-
NAL INSTALLATION
1.
Follow the instructions for "Horizontal Air Terminal In-
stallations", items 1 to 3.
2.
Continue adding components alternating inner and
outer venting. Ensure that all 5" venting and elbows have
sufficient vent spacers attached and each component is
securely fastened to the one prior. Attach the 5" telescopic
sleeve to the vent run.
Repeat using a 8" tel-
escopic sleeve. Secure
and seal as before. To
facilitate completion, at-
tach 5" and 8" couplers
to the air terminal.
3.
Install the air terminal.
See item 3 of
the Horizontal Air Terminal Installation.
Extend the 5" telescopic sleeve; connect
to the air terminal assembly. Fasten with
self tapping screws and seal. Repeat
using the 8" telescopic sleeve.

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 cen-
tred 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 flash-
ing 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 termi-
nal. Tighten securely.
Attach the vertical rain cap.
Spacers are at-
tached to the 5" in-
ner flex liner at pre-
determined intervals
to maintain a 1-1/4"
air gap to the 8" outer
liner. These spacers
must not be re-
moved.

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".
FIREPLACE VENT CONNECTION
1.
Install the 5 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 8 inch diameter aluminium flexible liner to
the fireplace. Attach and seal the joints.
