INSTALLATION
WALL AND CEILING PROTECTION
FOR SAFE AND PROPER OPERATION OF THE FIREPLACE, FOLLOW THE VENTING INSTRUCTIONS EXACTLY.
A HEAT SHIELD MUST BE USED IF THE WALL TERMINAL IS INSTALLED ON COMBUSTIBLE, EXTERIOR SURFACES.
NOTE: Only a clearance to combustibles of 1" all around the vent pipe is required.
HORIZONTAL INSTALLATION
This application occurs when venting through an exterior wall. Having determined the air terminal location, cut and frame a hole in an exterior wall with a minimum opening as required. See Note above. (As an alterna- tive to framing, a vent pipe shield may be installed, ensuring a 1" clearance to combustibles. See Figure 16.)
1.Mark and cut the vent pipe
shield to the determined depth of the combustible wall. Apply a bead of caulking (not supplied) to the framework or to the shield plate (in the case of a finished wall) and se- cure the shield through the opening to the interior wall. The final location of the vent pipe shield should maintain the required clearance to the 8" vent pipe / liner. (See note above). Do not fill this cavity with any type of material. Ap- ply 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 / liner is installed in its final position, apply sealant between the pipe / liner and the firestop spacer.

1.Determine the air terminal location, cut and frame 10 inch open-
ings in the ceiling and the roof to provide the minimum 1 inch clearance between the fireplace pipe / liner and any combustible material. Try to center the exhaust pipe loca- tion midway between two joist 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 insula- tion, 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 sup- plied) to the frame- work 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. FIGURE 18. A firestop must be placed on the bottom of each framed open- ing 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 clear- ance to combustibles. Once the vent pipe / liner is installed in its final position, apply sealant between the pipe / liner and the firestop spacer.
