Vertical Air Terminal Installation - Napoleon Fireplaces LHD62N Instructions D'installation Et D'opération

4.2.2 VERTICAL AIR TERMINAL INSTALLATION

MAINTAIN A MINIMUM 2" (51mm) SPACE BETWEEN THE AIR INLET BASE AND THE STORM COLLAR.
Fasten the roof support to the roof using the screws provided. The
A.
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.
Stretch the inner fl ex pipe to the required length. Slip the
B.
inner fl ex pipe a minimum of 2" (51mm) over the inner pipe
of the air terminal connector and secure with 6 #8 screws.
Seal using a heavy bead of high temperature sealant
W573-0007 (not supplied).
Repeat using the outer fl ex pipe, using a heavy bead of
C.
high temperature sealant W573-0002 (not supplied).
Thread the air terminal connector / vent pipe assembly down
D.
through the roof. The air terminal must be positioned vertically
and plumb. Attach the air terminal connector to the roof support,
ensuring that the top of the air terminal is 16" (406mm) above the
highest point that it penetrates the roof.
Remove nails from the shingles, above and to the sides of the
E.
air terminal connector. Place the fl ashing over the air terminal
connector leaving a min. 3/4" (19mm) of the air terminal connector
showing above the top of the fl ashing. Slide the fl ashing
underneath the sides and upper edge of the shingles. Ensure that
the air terminal connector is properly centred within the fl ashing,
giving a 3/4" (19mm) margin all around. Fasten to the roof.
Do not nail through the lower portion of the fl ashing. Make
weather-tight by sealing with caulking. Where possible, cover
the sides and top edges of the fl ashing with roofi ng material.
Aligning the seams of the terminal and air terminal connector,
F.
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.
Apply a heavy bead of weatherproof caulking 2" (51mm)
G.
above the fl ashing. 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.
