4. If more than one length of liner needs to be used to
reach the stove, couple them together as illustrated in
FIGURE 24. Seal the joints using the same procedure as
described above.
The vent system must be supported approximately every
10 feet along a horizontal run. Use supports or equivalent
non-combustible strapping to maintain the 1" clearance
from combustibles.
1. Fasten the roof
support to the roof us-
ing 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 juris-
diction or the optional
roof support.
2. Slip a 4" diameter length of aluminium flexible liner a
minimum of 2" over the inner sleeve of the air terminal.
Secure to the sleeve using 3 screws
and flat washers. Seal the joint and
screw heads using high temperature
sealant. Repeat using a 7" diameter
length of rigid piping.
If the attic space is tight, we rec-
ommend adding sufficient lengths
of 7" rigid piping, secured and
sealed as necessary.
3. Thread the air terminal pipe assembly down through
the roof support and attach, ensuring that a minimum 16"
of air terminal will penetrate the roof when fastened. The
air terminal must be located vertically and plumb.
4. 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
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 seal-
ing with caulking.
Where possible, cover the sides and top edges of the flash-
ing with roofing material.
5. Apply a heavy bead of waterproof 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
air exhaust slots onto the air terminal. Tighten securely.
6. Attach the vertical rain cap.

VERTICAL VENTING INSTALLATION
FOR SAFE AND PROPER OPERATION OF THE
STOVE, FOLLOW THE VENTING INSTRUCTIONS
EXACTLY.
FOR HORIZONTAL RUNS, BOTH WOLF STEEL AND
SIMPSON DURA-VENT VENTING COMPONENTS MAY
HAVE A 0" RISE PER FOOT.
FOR OPTIMUM PERFORMANCE IT IS RECOM-
MENDED THAT ALL 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 SEALANT OR BLACK
HIGH TEMP MILL PAC WITH THE EXCEPTION OF
THE FIREPLACE EXHAUST FLUE COLLAR WHICH
MUST BE SEALED USING MILL PAC (NOT
SUPPLIED).
1. Stretch the 4" diameter aluminium flexible liner to the
required length taking into account the additional length
needed for the finished wall surface.
Spacers are attached to the 4" inner flex liner at predeter-
mined intervals to maintain a 1-1/4" air gap to the 7" outer
stove pipe. These spacers must not be removed.
Slip a 4" diameter length of aluminium flexible liner a mini-
mum of 2" over the inner sleeve of the air terminal. Secure
to the sleeve using 3 screws. Seal the joint and screw
heads using the high temperature sealant.
2. Slip the first section of 7" diameter stove pipe a mini-
mum of 2" over the outer sleeve of the air terminal. Secure
to the sleeve using 3 screws. Seal the joint and screw
heads using high temperature sealant.
3. Insert the liners through the firestop / vent pipe shield.
Holding the air terminal (lettering in an upright, readable
position), secure to the exterior wall. Make weather tight by
sealing with caulking (not supplied). The air terminal mount-
ing plate may be recessed (up to 1½" maximum) into the
exterior wall or siding.
