4.2.4 VERTICAL AIR TERMINAL INSTALLATION

!WARNING

MAINTAIN A MINIMUM 2” 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 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		ROOF SUPPORT
	high temperature sealant W573-0002 (not supplied).
D.	Thread the air terminal connector / vent pipe assembly down through		INNER PIPE
	the roof. The air terminal must be positioned vertically and plumb.
	Attach the air terminal connector to the roof support, ensuring that the		AIR
	top of the air terminal is 16” above the highest point that it penetrates		TERMINAL
	the roof.	CONNECTOR

E.Remove nails from the shingles, above and to the sides of the air terminal connector. 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.
