Vertical Air Terminal Installation - Napoleon Fireplaces BL36NTE 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.
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 fl ex pipe to the required length. Slip the
inner fl ex pipe a minimum of 2" (51mm) over the inner pipe
of the air terminal connector and secure with a minimum of
3 #8 screws. Seal using a heavy bead of Mill Pac sealant
(W573-0007) (not supplied).
C. Repeat using the outer fl ex pipe, using a heavy bead
of red RTV silicone (W573-0002) (not supplied) and a
minimum of 3 #8 screws.
D. Thread the air terminal connector / vent pipe assembly down 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" (40.6cm) above the highest point
that it penetrates the roof.
E. Remove nails from the shingles, above and to the sides of the 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 centered 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.
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" (51mm)
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.

If more vent pipe needs to be used to reach the appliance see
