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.
*The vent system must be supported every 3 feet, for both vertical and horizontal runs. Use Wolf Steel support
HORIZONTAL AIR TERMINAL INSTALLATION
1.Stretch the 4" diameter aluminium flexible liner 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, supplied with the unit, 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.
2.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.
3.Insert the liners through the firestop. Position and secure the fireplace using the nailing tabs (2 per side) and/or secure to the floor using #10 hex head screws (not supplied). The liners should be flush with the exterior wall.
The air terminal may be recessed into the exterior wall or siding by ½", the depth of the return flange.
4.From outside, apply a bead of the high temperature sealant to the inside of both liners, approximately 1" from the end of each liner.
5.Holding the air terminal (lettering in an upright, read- able position), insert into both liners with a twisting motion to ensure that both the terminal sleeves engage into the liners / sealant. Secure the terminal to the exterior wall and make weather tight by sealing with caulking (not supplied).

6.If more than one length of liner needs to be used to reach the fireplace, couple them together as illustrated. Seal the joints using the same procedure as described in points 2 and 3. The vent system must be supported every 3 feet, for both vertical and horizontal runs. Use Napoleon support

VERTICAL AIR TERMINAL INSTALLATION
1.Fasten the roof support to the roof using the screws provided. The roof support is optional. The venting is to be adequately supported using either an alternate method suitable to the authority hav-
ing jurisdiction or the optional | FIGURE 17 | |

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 the 7" diam- | FIGURE 18 |

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 minimum 16" of air terminal will penetrate the roof when fastened.
DO NOT CLAMP THE FLEXIBLE ALUMINIUM LINER.
5.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air termi- nal and slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal is properly cen- tred within the flashing, giving a 3/4" margin all around. Fasten to the roof. Do not nail through the lower portion of the flashing. Make
* All horizontal runs must have a 1 inch rise per foot.
