USING FLEXIBLE VENT COMPONENTS
Use only approved aluminum flexible liner kits marked:
“Wolf Steel Approved Venting” as identified by the stamp only on the 7” outer liner.
For safe and proper operation of the fireplace, follow the venting instructions exactly.
All inner exhaust and outer intake vent pipe joists may be sealed using either Red RTV high temp silicone seal- ant or Black high temp Mill Pac with the exception of the fireplace exhaust flue collar which must be sealed using Mill Pac (not supplied).
Spacers are attached to the inner flex liner at predetermined intervals to maintain a
spacers must not be removed.
HORIZONTAL AIR TERMINAL INSTALLATION
1.Cut or frame a hole in an exterior wall with a minimum round or square opening of 111/2” W x 111/2” H. Secure the firestop spacer over the opening to the interior wall.
Secure the terminal to the terminal extension plate if required (see figure 18). The cover plate of the
2.Stretch the 4” diameter aluminum flexible liner to the required length taking into account the additional length needed for the finished wall surface. Slip the liner 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.
3.Using the 7” diameter flexible aluminum liner, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal as before.
