4.3.3 VERTICAL AIR TERMINAL INSTALLATION
A. Move the appliance into position.
B. 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.
C. Apply high temperature sealant (not supplied) to the outer edge of
the inner sleeve of the air terminal. Slip the inner coupler a minimum
of 2" (51mm)over the sleeve and secure using 3 screws.
D. Apply high temperature sealant (not supplied) to the outer edge of
the of the outside sleeve of the air terminal connector. Slip the outer
coupler over the sleeve and secure as before. Trim the outer coupler
even with the inner coupler end.
E. Thread the air terminal connector / vent pipe assembly down through
the roof support and attach, ensuring that a minimum 16" (406mm)
of air terminal connector will penetrate the roof when fastened. If
the attic space is tight, we recommend threading the Wolf Steel vent pipe collar or equivalent loosely
onto the air terminal connector / vent pipe assembly as it is passed through the attic. The air terminal
connector must be located vertically and plumb.
F. Remove nails from the shingles, above and to the sides of the air terminal
connector. Place the fl ashing over the air terminal connector and slide it
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.
G. Apply a heavy bead of waterproof 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 connector and the collar is achieved.
H. Continue adding rigid venting sections, sealing and securing as above. Attach the inner collapsed
telescopic sleeve to the last section of rigid piping. Secure with screws and seal. Repeat using the
outer telescopic sleeve.
I. Run a bead of high temperature sealant (not supplied) around the outside of the inner exhaust fl ue
collar on the appliance. Pull the telescopic sleeve a minimum of 2" (51mm) onto the collar. Secure with
3 screws. Repeat with the outer telescopic sleeve.
J. In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will
prevent any materials, such as insulation, from fi lling up the 1" (25mm) air space around the pipe.
