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.
6. Aligning the seams of the terminal and air terminal
connector, place the terminal over the air terminal connector
making sure the liner goes into the hole in the terminal.
Secure with the three screws provided.
7. Apply a heavy bead of weatherproof caulking 2 inches
above the flashing. Note: Maintain a minimum 2” space
between the air inlet base and the storm collar. Install the
storm collar around the air terminal and slide down to the
caulking. Tighten to ensure that a weather-tight seal

between the air terminal and the collar is achieved.

1. Stretch the 4" diameter alu-

minum flexible liner to the re-
quired 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 aluminum 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 red RTV or Mill Pac high temperature sealant
(not supplied).

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 red RTV 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

" maximum) into the

exterior wall or siding.

4. If more than one length of liner needs to be used to

reach the stove, couple them together as illustrated in
FIGURE 18. 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.
