Follow guidelines in section 7.1.2.1 regarding the rel-
ative position of the exhaust and terminal.
Follow manufacturer's installation guidelines of the
AT-4.
This system consists of a 4" air intake hood, a 5" x 4" re-
ducer and a 26½" long, insulated Aerocowl exhaust ter-
mination. This termination has a zero clearance rating to
combustibles. Do not install the vacuum relief damper
("not needed").
Cut a 6" round opening in the outside wall at the se-
lected location. Apply silicone caulking to the back-
side of the outer face plate and secure it to the
outside wall.
Insert the Aerocowl termination from the outside up
to the outer wall stop. Ensure slope of ¼" per foot to
outside.
Slide inner plate on the termination up to the inside
wall, tighten the gear clamp and secure the inner
plate to the wall.
For Aerocowl AT-4 installations in Canada less than
7 ft. above ground, install a cage/screen over the ter-
mination to prevent injury from touching hot surfaces.

clearance concentric combination intake/exhaust termi-
nation with a 4" provision for fresh air intake piping. Do
not install the vacuum relief damper ("not needed").
Cut a round 7" diameter opening in the outside wall
at the selected location.
Remove the 4" air intake collar from the termination
assembly.
