INSTALLATION
WALL AND CEILING PROTECTION
HORIZONTAL VENT SECTIONS: A minimum clearance of 2” all around the vent pipe on all horizontal runs to combustibles is required. Use firestop spacer
VERTICAL VENT SECTIONS: A minimum of 1” all around the vent pipe on all vertical runs to combustibles is required except for clearances in fireplace enclosures. Use firestop spacer
HORIZONTAL INSTALLATION |
| VERTICAL INSTALLATION |
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 11 3/4“ wide by 11 3/4“ high to accommodate the firestop assembly. Dry fit the firestop assembly before proceeding to ensure the brackets on the rear surface fit within the horizontal framing.
As an alternative to framing, the vent pipe can be enclosed in the wall using Napoleon® vent sleeve VS47KT.
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.
1.Apply a bead of caulking (not supplied) around the outer edge of the inside surface of the firestop assembly, fit the firestop assembly to the hole and secure using the 4 screws
2.Once the vent pipe is installed in its final position, apply high temperature sealant
NOTE: DO NOT FILL THE CAVITY BETWEEN THE PIPE AND THE FIRESTOP SLEEVE WITH ANY TYPE OF MATERIAL.

1. Determine the air terminal location, cut and
frame 9 3/4” openings in the ceiling and the roof to provide the minimum 1“ clearance between the vent pipe and any combustible material. Try to center the vent pipe location midway between two joist to prevent having to cut them. Use a plumb bob to line up the center of the openings. material.
A vent pipe shield will prevent any materials such as insulation, from filling up the 1" air space around the pipe. Nail headers between the joist for extra support.
2.Apply a bead of caulking (not supplied) to the
framework or to the Wolf
Steel vent pipe shield plateCAULKING or equivalent (in the case of
a finished ceiling), and secure over the opening in
the ceiling. A firestop must be placed on the bottom of each framed opening in a roof or ceiling that the venting system passes through. Apply a bead of caulking (not supplied) all around and place a firestop spacer over the vent shield to restrict cold air from being drawn into the room or around the fireplace. Ensure that both spacer and shield maintain the required clearance to combustibles. Once the vent pipe is installed in its final position, apply sealant between the vent pipe and the firestop spacer.
