5.5.3 VERTICAL AIR TERMINAL INSTALLATION
NOTE: Before attaching elbows to the collars on the back of the appliance, 1 1/2" (38.1mm) will need to
EN
be trimmed off the 4" (101.6mm) collar.
REAR VENT APPLICATION: Attach 4" (101.6mm) and 7" (177.8mm) elbows to the appliance. Secure with
three screws and seal the joints and screw heads using high temperature
sealant. Proceed to step A below.
TOP VENT APPLICATION:
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
three 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" (40.6cm)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 positioned 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.
REAR VENT APPLICATION:
I.
Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of the inner
elbow. Pull the telescopic sleeve a minimum of 2" (50.8mm) onto the elbow. Secure with three
screws. Repeat with the outer telescopic sleeve.
TOP VENT APPLICATION:
J.
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 three screws. Repeat with the outer telescopic sleeve.
K.
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
