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).

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.
