4.3.2 EXTENDED HORIZONTAL AND CORNER TERMINAL INSTALLATION
A.
Follow the instructions for "HORIZONTAL AIR TERMINAL INSTALLATIONS" section.
B.
Continue adding components alternating inner rigid pipe and outer rigid pipe. Ensure
that all inner rigid pipe and elbows have sufficient vent spacers attached and each
component is sealed and securely fastened to the one prior. Attach the inner telescopic
sleeve to the vent run. Repeat using the outer telescopic sleeve. Seal and secure as
before. To facilitate completion, attach inner and outer couplers to the air terminal.
C.
Install the air terminal. See “HORIZONTAL AIR TERMINAL INSTALLATION” section.

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” 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” 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” 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
roo
fi
ng material.
G.
Apply a heavy bead of waterproof caulking 2” 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” 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” air space around the pipe.
