6. If more than one length of liner needs to be used to
reach the fireplace, couple them together as illustrated.
Seal the joints using the same procedure as described in
points 2 and 3. The vent system must be supported every 3
feet, for both vertical and horizontal runs. Use Napoleon
support W010-0370 or equivalent noncombustible strap-
ping to maintain the 1" clearance from combustibles as
well as to prevent sagging.
1. Fasten the roof support
to the roof using the screws
provided. The roof support is
optional. The venting is to be
adequately supported using
either an alternate method
suitable to the authority hav-
ing jurisdiction or the optional
roof support.
2. Stretch the 4" diameter aluminium flexible liner to the
required length. Slip the liner a minimum of 2" over the
inner sleeve of the air terminal and secure with 3 #8 screws.
Seal using a heavy bead of the high temperature sealant.
3. Repeat using the 7" diam-
eter aluminium flexible liner.
4. Thread the air terminal pipe
assembly down through the roof.
The air terminal must be located
vertically and plumb. Attach the
air terminal assembly to the roof
support, ensuring that a
minimum 16" of air terminal will
penetrate the roof when
fastened.
DO NOT CLAMP THE FLEXIBLE ALUMINIUM LINER.
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.
Use only approved aluminum flexible liner kits marked:
"Wolf Steel Approved Venting" as
identified by the stamp only on the 7”
outer liner.
For safe and proper operation of the fireplace, follow
the venting instructions exactly.
* The vent system must be supported every 3 feet, for
both vertical and horizontal runs. Use Wolf Steel support
W010-0370 or equivalent non-combustible strapping to
maintain the 1" clearance from combustibles as well as to
prevent sagging.
1. Stretch the 4" diameter aluminium flexible liner to the
required length taking into account the additional length
needed for the finished wall surface. Apply a heavy bead of
the high temperature sealant, supplied with the unit, to the
inside of the 4" liner approximately 1" from the end. Slip the
liner a minimum of 2" over the fireplace vent collar and
secure with 3 #8 screws.
2. Using the 7" diameter flexible aluminium liner, apply
sealant, slide a minimum of 2 " over the fireplace combus-
tion air collar and secure with 3 #8 screws.
3. Insert the liners through the firestop. Position and
secure the fireplace using the nailing tabs (2 per side)
and/or secure to the floor using #10 hex head screws (not
supplied). The liners should be flush with the exterior wall.
The air terminal may be recessed into the exterior wall
or siding by ½", the depth of the return flange.
4. From outside, apply a bead of the high temperature
sealant to the inside of both liners, approximately 1" from
the end of each liner.
5. Holding the air terminal (lettering in an upright, read-
able position), insert into both liners with a twisting motion
to ensure that both the terminal sleeves engage into the
liners / sealant. Secure the terminal to the exterior wall and
make weather tight by sealing with caulking (not supplied).
