INSTALLATION / FRAMING
WALL AND CEILING PROTECTION
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 square opening of 8” W x 8” H.
IMPORTANT: For optimum performance, The vent pipe should rise ¼” per foot of run.
1.Apply a bead of caulking all around and place the firestop spacer over the framework 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. Secure the spacer in place using the 4 longer screws supplied. Once the vent pipe is installed in its final position, apply high temperature sealant (not supplied) between the pipe and the firestop spacer.
USING FLEXIBLE VENT COMPONENTS
USE ONLY WOLF STEEL LTD. 3” / 5” FLEXIBLE VENT COMPONENTS.

FIGURE 4
Use only approved aluminum flexible vent kits marked:
“Wolf Steel Approved Venting” as identified by the stamp on the flexible vent pipe.
For safe and proper operation of the fireplace, follow the venting instructions exactly.
All inner exhaust and outer intake vent pipe joints may be sealed using either Red RTV high temp silicone sealant or Black high temp Mill Pac with the exception of the fireplace exhaust flue collar which must be sealed using Mill Pac
Spacers are attached to the flexible vent pile at predetermined intervals to maintain a 3/4” air gap to the outer flexible vent
pipe. These spacers must not be removed.
AIR TERMINAL INSTALLATION
1.Cut or frame a hole in an exterior wall with a minimum rectangular opening of 8” W x 8” H. Secure the firestop spacer over the opening to the interior wall. (FIGURE 4)
2.Stretch the 3” diameter aluminum flexible vent pipe to the required length taking into account the additional length needed for the finished wall surface. Apply a heavy bead of the high temperature sealant. Slip the vent pipe a minimum of 2” over the inner sleeve of the air terminal and secure with
3#8 screws.
3.Using the 5” diameter flexible vent pipe, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal as before.
4.Insert the vent pipe through the firestop maintaining the required clearance to combustibles. Secure the terminal to the exterior wall (lettering in an upright, readable position) and make weather tight by sealing with caulking (not supplied).
5.If additional vent pipe is required, couple them together as illustrated. The vent system must be suppored approximately every 3 feet for both vertical and horizontal runs. Use non- combustible strapping to maintain the minimum 1” clearance to combustibles from the vent pipe.
