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.
HORIZONTAL AIR TERMINAL INSTALLATION
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 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 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 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.
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).
5.Apply a heavy bead of the high temperature sealant to the inside of the 4" 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 7" 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.
VERTICAL AIR TERMINAL INSTALLATION

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

1. Fasten the roof sup-

| screws provided. The |
| roof support is optional. |
| In this case the venting |
| is to be adequately sup- |
| ported using either an al- |
| ternate method suitable |
| to the authority having ju- |
| risdiction or the optional |
| roof support. |
2.Stretch the 4" diameter aluminium flexible liner to the required length. Slip the liner a minimum of 2" over the inner sleeve of the air terminal
and secure with 3 #8 screws. Seal using a heavy bead of the high temperature sealant.
3.Repeat using 7" diameter aluminium flexible liner.
4.Thread the air terminal pipe assembly down through the roof.
The air terminal must be located vertically and plumb. Attach the air terminal assembly to the roof support, ensuring that a mini-
mum 16" of air terminal will penetrate the roof when fas- tened.
DO NOT CLAMP THE FLEXIBLE ALUMINIUM LINER.
