Dry fi t the fi restop assembly before proceeding to ensure the brackets on the rear surface fi t 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, fi t the fi restop assembly to the hole and secure using the 4 screws (W415-0026) supplied in your manual baggy. 2. Once the vent pipe is installed in its final position, apply high temperature sealant W573-0002 (not supplied) between the pipe, and the firestop. NOTE: DO NOT FILL THE CAVITY BETWEEN THE VENT PIPE AND THE FIRESTOP SLEEVE WITH ANY TYPE OF MATERIAL. W415-0661 / C / 02.20.08 FIGURE 48 FIGURE 48 ADJUSTABLE FIRESTOP INSTALLATION BGD42CF ONLY Apply a bead of caulking all around the edge of the opening and place the firestop top, so that the vent shield covers the top of the vent within the opening. 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 firestop bottom against the firestop top and secure the two together. Adjust the assembly to ensure it is tight to the vent. Secure firestop to wall. 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. This restricts cold air from being drawn into the room or around the fireplace. See Figures 49a-c. VENT SHIELD FIRESTOP TOP FIRESTOP BOTTOM FIGURE 49b FIGURE 49a FIGURE 49c Where the opening in the outside wall has been cut 13" tall to provide 2" clearance from the vent pipe, terminal extension plate W500-0206 must be used to cover the opening. VERTICAL INSTALLATION 1. Determine the air terminal location, cut and frame 9 3/4" for the BGD36CF(G), or 10 3/4" for the BGD42CF square opening in the ceiling and an opening in the roof to provide the minimum 1" clearance between the fireplace vent pipe and any combustible material. Try to center the exhaust 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 BGD36CF(G) = 9 3/4” space around the pipe. Nail BGD42CF = 10 3/4” 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 FIGURE 50 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 FIGURE 51 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 high temperature sealant W573-0002 (not supplied) between the vent pipe and the firestop spacer. 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.

USING FLEXIBLE VENT COMPONENTS HORIZONTAL AIR TERMINAL INSTALLATION THE BGD36CF(G) USES: 4" EXHAUST / 7" AIR INTAKE VENT PIPE WITH A MINIMUM 6" BEND RADIUS THE BGD42CF USES: 5" EXHAUST / 8" AIR INTAKE VENT PIPE WITH A MINIMUM 8" BEND RADIUS Use only approved fl exible liner kits marked: "Wolf Steel Approved Venting" as identifi ed by the stamp only on the 7" outer vent pipe. ELBOW SPACER 1. Stretch the exhaust vent pipe to the required length taking into account the additional length needed for the fi nished wall surface. Slip the vent pipe a minimum of 2" over the inner sleeve of the air terminal and secure with 3 #8 screws. Apply a heavy bead of the high temperature sealant W573-0002 (not supplied). 2. Using the air intake vent pipe, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal as before. 6. If more fl exible vent pipe needs to be used to reach the fi replace, coupler them together as...
