4.3.2 EXTENDED HORIZONTAL AIR TERMINAL INSTALLATION
A. Follow the instructions for "HORIZONTAL AIR TERMINAL
INSTALLATION", items 1 to 3.
B. Continue adding components alternating flexible and rigid vent
pipes. Ensure that all inner flex vent pipes and elbows have
sufficient vent spacers attached and each component is securely
fastened to the one prior. Attach the telescopic sleeve to the vent run.
Secure and seal. To facilitate completion, attach inner and outer couplers
to the air terminal.
C. Install the air terminal. See item 3 of the “HORIZONTAL AIR TERMINAL
INSTALLATION”. Extend the telescopic sleeve; connect to the air terminal
assembly. Fasten with self tapping screws and seal.

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 W573-0007 (not supplied) to the
outer edge of the inner sleeve of the air terminal. Slip the inner
coupler a minimum of 2” (50.8mm)over the sleeve and secure using
3 screws.
D. Apply high temperature sealant W573-0002 (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”
(406.4mm) 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”
(19.1mm) 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” (50.8mm) 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 W573-0007 (not supplied) around the outside of the inner
collar on the appliance. Pull the telescopic sleeve a minimum of 2” (50.8mm) 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” (25.4mm) air space around the pipe.
