4.4.3 VERTICAL AIR TERMINAL INSTALLATION (RIGID)

Move the appliance into position.

Fasten the roof support to the roof using the screws provided. The
B.
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.
Apply high temperature sealant W573-0007 (not supplied) to the
C.
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.
Apply high temperature sealant W573-0002 (not supplied) to the
D.
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.
Thread the air terminal connector / vent pipe assembly down
E.
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.
Remove nails from the shingles, above and to the sides of the air terminal
F.
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.
Apply a heavy bead of waterproof caulking 2" (50.8mm) above the fl ashing. Install the storm collar
G.
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.
Continue adding rigid venting sections, sealing and securing as above. Attach the inner collapsed
H.
telescopic sleeve to the last section of rigid piping. Secure with screws and seal. Repeat using the
outer telescopic sleeve.
Attach horizontal venting to the back of the appliance, see "HORIZONTAL AIR TERMINAL
I.
INSTALLATION" section. Attach an inner and outer 90º elbow to this venting, secure and seal as
outlined obove.
Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of the inner
J.
elbow on the venting. Pull the telescopic sleeve a minimum of 2" (50.8mm) onto the elbow. Secure with
3 screws. Repeat with the outer telescopic sleeve.
In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will
K.
prevent any materials, such as insulation, from fi lling up the 1" (25.4mm) air space around the pipe.
