determined the correct height for the air terminal location, cut and frame
a hole in the exterior wall 14 1/2" wide by 14 1/2" high to

assembly before proceeding to ensure the brackets on
the rear surface fit to the inside surface of the horizontal
framing.
NOTE: The firestop assembly must be installed with the
vent shield to the top.
The length of the vent shield may be cut shorter for combustible
walls that are less than 8 1/2" thick but the vent shield must extend
the full depth of the combustible wall.

surface of the firestop assembly, fit the firestop assembly to the hole
and secure using the 4 screws (supplied in your manual baggie).
B. Once the vent pipe is installed in its final position, apply high temperature sealant W573-0007 (not
