A.

Fasten the roof support to the roof using the screws provided. The

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.

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.

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” above the

flashing. 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.
