Use only approved aluminum flexible liner kits marked
" Wolf Steel Approved Venting" as identified by the
stamp only on the 7" outer liner.
For optimum performance it is recommended that all
horizontal runs have a minimum ¼ inch rise per foot
using flexible venting.
1. Stretch the 4" 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 Mill Pac, to the inside of the
4" liner approximately 1" from the end. Slip the liner a mini-
mum of 2" over the fireplace vent collar and secure with 3
#8 screws.
2. Using the 7" diameter flexible aluminum liner, apply seal-
ant, slide a minimum of 2" over the fireplace combustion
air collar and secure with 3 #8 screws.
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.
The air terminal may be recessed into the exterior wall
or siding by 1½", the depth of the return flange.
4. From outside, apply a bead of the high temperature seal-
ant 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 in FIGURE 13. The vent
system must be supported approximately every 3 feet for
both vertical and horizontal runs. Use Napoleon support
ring assembly W010-0370 or equivalent noncombustible
strapping to maintain the minimum 1" clearance to com-
bustibles.
1. Fasten the roof support to the
roof using the screws pro-
vided. The roof support is
optional. In this case the
venting is to be ad-
equately supported us-
ing either an alternate
method suitable to the
authority having jurisdic-
tion or the optional roof
support.
2. Stretch the 4" diameter alumi-
num 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 7" diameter alu-
minum flexible liner.
4. Thread the air terminal pipe as-
sembly down through the roof.
The air terminal must be located vertically and plumb. At-
tach the air terminal assembly to the roof support, ensur-
ing that a minimum 16" of air terminal will penetrate the
roof when fastened.
DO NOT CLAMP THE
FLEXIBLE ALUMINUM
LINER.
5. Remove nails from
the shingles, above
and to the sides of the
chimney. Place the
flashing over the air ter-
minal and slide it un-
derneath the sides and
upper edge of the shingles. Ensure that the air terminal is
properly centered 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 centered between
the air intake and the air exhaust slots onto the air termi-
nal. Tighten securely. Attach the vertical rain cap.

For safe and proper operation of the fireplace, follow the
venting instructions exactly.
All inner exhaust and outer intake vent pipe joists 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).
