INSTALLATION
WALL AND CEILING PROTECTION
For optimum performance, it is recommended that horizontal runs have a minimum 1" rise per foot when using Simpson
For safe and proper operation of the fireplace,
follow the venting instructions exactly.
HORIZONTAL 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 9 7/8" wide by 11 3/8" high to accommodate the firestop assembly. Dry fit the firestop assembly before proceeding to ensure the brackets on the rear surface fit to the inside surface of the horizontal framing. Firestop spacer and shield do not limit the thickness of a wall. For wall construction when using less than 2" x 6" framing, the shield must be cut to suit.
As an alternative to framing, the vent pipe can be enclosed in the wall using Napoleon® vent sleeve VS47KT.
N OTE : 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 corner 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
/LINER AND THE FIRESTOP SLEEVE WITH ANY TYPE OF MATERIAL.
VERTICAL INSTALLATION
This application occurs when venting through a roof. Installation kits for various roof pitches are available from your Napoleon® dealer. See Accessories to order the specific kit required.
1.Determine the air terminal location, cut and frame a 9 3/4" square opening in the ceiling and the roof to provide the minimum clearance between the vent pipe and any combustible material. Try to center the vent pipe location
midway between two joists to prevent having to cut them. Use a plumb bob to line up the center of the openings.
Do not fill this space with any
type of 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 plate 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 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 pipe and the firestop assembly.

3. In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any materials, such as insulation, from filling up the 1" air space around the pipe.
