USING FLEXIBLE VENT COMPONENTS
Use only approved aluminum flexible liner kits marked:
FIGURE33
For optimum performance, it is recommended that
horizontal runs have a minimum ¼ inch rise per foot .
"Wolf Steel Approved Venting" as identified by the stamp only on the 8” outer liner.
For safe and proper operation of the fireplace, follow the venting instructions exactly.
HORIZONTAL AIR TERMINAL INSTALLATION
1.Stretch the 5" diameter aluminum 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 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.
2.Using the 8" diameter flexible aluminum liner, apply seal- ant, slide a minimum of 2" over the fireplace combustion air collar and secure with 3 #8 screws.

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

3.Insert the liners through the firestop. Position and se- cure the fireplace using the nailing tabs (2 per side) and/or secure to the floor using screws inserted through the two ¼" diameter holes in the front left and right corners of the base. The liners should be flush with the exterior wall.
5.From outside, apply a bead of the high temperature seal- ant to the inside of both liners, approximately 1" from the end of each liner.
5.Holding the air terminal (lettering in an upright, readable position), insert into both liners with a twisting motion to ensure that both the terminal sleeves engage into the lin- ers / sealant. Secure the terminal to the exterior wall and make weather tight by sealing with caulking (not supplied).
6.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 Napoleon support ring assembly
VERTICAL AIR TERMINAL INSTALLATION
1. Fasten the roof support | FIGURE36 |
| |
to the roof using the |
|
screws provided. The roof |
|
support is optional. In this |
|
case the venting is to be |
|
adequately supported us- |
|
ing either an alternate |
|
method suitable to the au- |
|
thority having jurisdiction or the optional roof support.
FIGURE37 | 2. Stretch the 5" diameter alumi- |
num 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 8" diameter alu-
minum flexible liner.
5. 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 termi- nal will penetrate the roof when fastened.
DO NOT CLAMP THE

LINER.
