Use only approved aluminum flexible liner kits marked:
"Wolf Steel Approved Venting" as identified by the stamp only on the 8” outer liner.
FIGURE 18
For safe and proper operation of the fireplace, follow
the venting instructions exactly.
A VENT HEAT SHIELD MUST BE USED IF THE WALL TERMI-
NAL IS INSTALLED ON COMBUSTIBLE, EXTERIOR SUR-
FACES.
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.
5. Apply a heavy bead of the high temperature sealant,
supplied with the unit, to the inside of the 5" liner approxi-
mately 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 vent heat shield
must be installed only
when terminating hori-
zontally with no vertical
rise. Remove the two
screws nearest the vent
collars on the top of the
fireplace. Align the vent
heat shield (supplied) and
secure.See figure 37.

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 us-
ing either an alternate
method suitable to the au-
thority having jurisdiction or the optional roof support.
2. Stretch the 5" 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 8" 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 pen-
etrate the roof when fastened.
DO NOT CLAMP THE FLEXIBLE
ALUMINIUM LINER.

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).
