4.1.1 HORIZONTAL INSTALLATION
THE FIRESTOP ASSEMBLY MUST BE INSTALLED WITH THE VENT SHIELD TO THE TOP.
TERMINALS MUST NOT BE RECESSED INTO A WALL OR SIDING MORE THAN THE DEPTH OF THE
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" 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.
