EXTENDED HORIZONTAL AND CORNER
AIR TERMINAL INSTALLATION
1. Follow the instructions
for "Horizontal Air Terminal
Installations", items 1 to 3.
2. Continue adding
components alternating 4"
and 7" vent pipes. Ensure
that all 4" vent pipes and elbows have
suffi cient vent spacers attached and each
component is securely fastened to the
one prior. Attach the 4" telescopic sleeve
to the vent run.
Repeat using a 7" telescopic sleeve.
Secure and seal as before. To facilitate completion, attach 4"
and 7" couplers to the air terminal.
3. Install the air terminal. See item 3 of the Horizontal Air
Terminal Installation. Extend the 4" telescopic sleeve; connect
to the air terminal connector. Fasten with self tapping screws
and seal. Repeat using the 7" telescopic sleeve.
VERTICAL VENTING INSTALLATION
REAR VENT APPLICATION: Attach 4" and 7" elbows to
the fi replace. Secure with 3 screws and seal the joints and
screw heads using high temperature sealant. Proceed to
step 1 below.
TOP VENT APPLICATION:
1. Move the fi replace into position.
2. Fasten the roof support to the roof using the screws
provided.The roof support is optional. The venting is to
be adequately supported using either an alternate method
suitable to the authority having jurisdiction or the optional
roof support.
3. Apply high temperature sealant W573-0007 (not
supplied) to the outer edge of the inner pipe of the air terminal
connector. Slip the 4" rigid vent pipe pipe a minimum of 2"
over the inner pipe of the air terminal connector and secure
using 3 screws.
4. Apply high temperature sealant W573-0002 (not
supplied) to the outer edge of the
of the outter pipe of the air terminal
connector. Slip the 7" rigid vent
pipe over the outer pipe of the air
terminal connector and secure as
before. Trim the 7" rigid vent pipe
even with the end of the 4" rigid
vent pipe.
5. 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 connecter /
vent pipe assembly as it is passed
through the attic. The air terminal
connector must be located vertically
and plumb.

around the air terminal and slide down to the caulking. Tighten
to ensure that a weather-tight seal between the air terminal
and the collar is achieved.
