3.2.2 VERTICAL AIR TERMINAL INSTALLATION
A. 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.
B. Stretch the inner flex pipe to the required length. Slip the inner flex
pipe a minimum of 2” over the inner pipe of the air terminal connector
and secure with 3 #8 screws. Seal using a heavy bead of high
temperature sealant W573-0007 (not supplied).
C. Repeat using the outer flex pipe, using a heavy bead of high temperature
sealant W573-0002 (not supplied).
D. Thread the air terminal connector / vent pipe 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.
E. 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.
F. Aligning the seams of the terminal and air terminal connector, place the
terminal over the air terminal connector making sure the vent pipe goes
into the hole in the terminal. Secure with the three screws provided.
G. Apply a heavy bead of weatherproof caulking 2" above the flashing.
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.
H. If more vent pipe needs to be used to reach the fireplace see “HORIZONTAL
AIR TERMINAL INSTALLATION” section.
