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.
HORIZONTAL AIR TERMINAL INSTALLATION
AVENT SHIELD MUST BE USED IF THE WALL TERMINAL IS INSTALLED ON COMBUSTIBLE, EXTERIOR SURFACES.
1.Cut or frame a hole in an exterior wall with a minimum round or square opening of 10½ inches. Secure the firestop spacer over the opening to the interior wall.
2.Stretch the 5" diameter aluminum flexible liner to the required length taking into account the additional length needed for the finished wall surface. Slip the liner a mini- mum 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 8" diameter flexible aluminum liner, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal as before.

The air terminal mounting plate may be recessed into the exterior wall or siding by 1½", the depth of the return flange.

4.Insert the liners through the firestop maintaining the required clearance to combustibles. Holding the air termi- nal (lettering in an upright, readable position), secure to the exterior wall and make weather tight by sealing with caulking (not supplied).
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 seal- ant or Black high temp Mill Pac with the exception of the fireplace exhaust flue collar which must be sealed us- ing Mill Pac (not supplied).
5.Apply a heavy bead of the high temperature sealant, Mill Pac, to the inside of the 5" liner approximately 1" from the end. Slip the liner a minimum of 2" over the fireplace vent collar and secure with 3 #8 screws.
6.Using the 8" diameter flexible aluminium liner, apply sealant, slide a minimum of 2" over the fireplace combus- tion air collar and secure with 3 #8 screws.
7.If more liner needs to be used to reach the fireplace, couple them together as illustrated. The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use noncombustible strapping to maintain the minimum 1" clearance to combustibles.
8.The heat shield must
be installed only when ter- | FIGURE 20 |

VERTICAL AIR TERMINAL INSTALLATION
1.Fasten the roof support to the roof using the screws provided.
The roof support is optional. In this case the venting is to be adequately supported using either an alternate method suitable to the
authority having

2.Stretch the inner aluminum flex liner to the required length. Slip the liner a minimum of 2” over the inner sleeve of the air terminal connector
INNER and secure with 3 #8 screws. Seal SLEEVEusing a heavy bead of the high
temperature sealant.
