HORIZONTAL VENT SECTIONS: A minimum clearance of 2" all around the vent pipe on all horizontal runs to combustibles is required. Use fi restop spacer W010-1778 (supplied).

VERTICAL VENT SECTIONS: A minimum of 1" all around the vent pipe on all vertical runs to combustibles is required. Use fi restop spacer W500-0367 (not supplied).

the air terminal location, cut and frame a
hole in an exterior wall with a minimum

ADJUSTABLE FIRESTOP INSTALLATION

Apply a bead of caulking all around and place the fi restop top, so that the vent shield covers the top of the vent within the opening.

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.

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.	1. Determine the air terminal location, cut and frame 10 3/4" square
