For safe and proper operation of the fireplace, follow
the venting instructions exactly.
1. Stretch the 5" diameter aluminum 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 W573-0007 10.3oz tube (not
supplied), to the inside of the 5" 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 8" diameter flexible aluminum liner, apply high
temperature sealant or Red RTV Silcone in this location,
slide a minimum of 2" over the fireplace combustion air
collar and secure with 3 #8 screws.
The air teminal may be recessed into the exterior wall
or siding by 1½", the depth of the return flange.
3. Insert the liners through the firestop. Position and se-
cure the fireplace using the nailing tabs (2 per side) and/or
secure to the floor using screws inserted through the two
¼" diameter holes in the front left and right corners of the
base. The liners should be flush with the exterior wall.
5. From outside, apply a bead of the high temperature seal-
ant or Red RTV Silcone may also be used in this location,
to the inside of both liners, approximately 1" from the end
of each liner.

5. Holding the air terminal (lettering in an upright, readable
position), insert into both liners with a twisting motion to
ensure that both the terminal sleeves engage into the lin-
ers / sealant. Secure the terminal to the exterior wall and
make weather tight by sealing with caulking (not supplied).
6. 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 Napoleon support ring assembly
W010-0380 or equivalent noncombustible strapping to
maintain the minimum 1" clearance to combustibles.
1. Fasten the roof support to the roof using the screws
provided. The roof support is optional. In this case the
venting is to be adequately supported using either an
alternate method suitable to the authority having
jurisdiction or the optional roof support.
2. Stretch the inner aluminum
flex liner to the required length.
Slip the liner a minimum of 2”
over the inner sleeve of the
air terminal connector
and secure with 3 #8
screws. Seal using a
heavy bead of the high
temperature sealant.
3. Repeat using the outer aluminum
flex liner.
4. Thread the air terminal connector /
liner assembly down through the roof.
The air terminal must be located vertically
and plumb. Attach the air terminal
connector to the roof support, ensuring
that the top of the air terminal is 16”
above the highest point that it
penetrates the roof.
5. Remove nails from the shingles,
above and to the sides of the chimney.
Place the flashing over the air terminal
connector leaving a min. 3/4” of the
air terminal connector showing above
the top of the flashing. Slide the
flashing underneath the sides and upper edge of the
shingles. Ensure that the air terminal connector 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.
USING FLEXIBLE VENT COMPONENTS
Use only approved aluminum flexible liner kits marked:
"Wolf Steel Approved Venting"
as identified by the stamp only on the
8” outer liner.
For optimum performance, it is recommended that
horizontal runs have a minimum ¼ inch rise per foot .
All inner exhaust and outer intake vent pipe joints may
be sealed using either Red RTV high temp silicone seal-
ant or Black high temp Mill Pac with the exception of the
fireplace exhaust flue collar which must be sealed us-
ing Mill Pac (not supplied).
