This application occurs when venting through an exterior wall. Having
determined the correct height for the air terminal location, cut and
frame a hole in the exterior wall as illustrated to accommodate
the fi restop assembly.
The length of the vent shield may be cut shorter for
combustible walls that are less than 8 1/2” (215.9mm)
thick but the vent shield must extend the full depth of
the combustible wall.
A. Apply a bead of caulking (not supplied) all around and
place the fi restop top, so that the vent shield covers the
top of the vent within the opening.
B.
Place the fi restop bottom against the fi restop top and secure the
two together. Adjust the assembly to ensure it is tight to
the vent. Secure fi restop to wall. This restricts cold air
from being drawn into the room or around the
appliance. Ensure that both spacer and shield
maintain the required clearance to
combustibles. Once the vent pipe is
installed in its fi nal position, apply
sealant W573-0002 (not supplied)
between the vent pipe and the fi restop
spacer as illustrated.
