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. Figure 34.

2. Stretch the 4" ﬂ ex vent pipe to the required length.

Slip the 4" ﬂ ex vent 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). Figure 35.

NOTE: If using pipe clamps to connect vent

components, 3 screws must also be used to ensure the connection cannot slip off.

3. Repeat using the 7" ﬂ ex vent pipe, using a heavy bead of high temperature sealant

W573-0002 (not supplied). Figure 35.

4. 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. Figure 34. DO NOT CLAMP THE FLEX VENT

PIPE.

5. Remove nails from the shingles, above and to the sides of the chimney. Place the ﬂ ashing over the air terminal connector

leaving a min. 3/4" 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" 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. Figure 36.

6. 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. Figure 36.

7. Apply a heavy bead of weatherproof caulking 2" above the ﬂ ashing. 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.

Figure 36.

8. If more vent pipe needs to be used to reach the ﬁ replace, couple them together

as illustrated. The vent system must be supported approximately every 3 feet for

both vertical and horizontal runs. Use noncombustible strapping to maintain the

minimum 1" clearance to combustibles. Figure 33.

1. Install the 4" ﬂ ex vent pipe to the ﬁ replace. Secure with 3 screws and ﬂ at washers. Seal

the joint and screw holes using the high temperature sealant W573-0007 (not supplied).

2. Install the 7" ﬂ ex vent pipe to the ﬁ replace. Attach and seal the joints using the high

temperature sealant W573-0002 (not supplied).

USING RIGID VENT COMPONENTS

The vent system must be supported approximately every 3

feet for both vertical and horizontal runs. Use Wolf Steel vent

spacers W615-0033 every 3 feet on either side of each elbow

to maintain the minimum 1¼" clearance between the 7" rigid

vent pipe and 4" rigid vent pipes. Use Napoleon® support ring

assembly W010-0370 or equivalent noncombustible strapping

to maintain the minimum clearance to combustibles for both

vertical and horizontal runs.
