A VENT 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.
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-
minating horizontally with
no vertical rise. Remove
the two screws nearest
the vent collars on the top
of the fireplace. Align the
vent shield (supplied) and
secure.

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
jurisdiction or the optional
roof support.
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
and secure with 3 #8 screws. Seal
using a heavy bead of the high
temperature sealant.
3. Repeat using the outer aluminum flex
liner.
4. Thread the air terminal connector /
liner assembly down through the roof.
The air terminal must be located
vertically and plumb. Attach the air
terminal connector to the roof support,
ensuring that the top of the air terminal
is 16” above the highest point that it
penetrates the roof.

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).

Use only approved aluminum flexible liner kits marked:
"Wolf Steel Approved Venting" as
identified by the stamp only on the 7”
outer liner.
USING FLEXIBLE VENT COMPONENTS
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).
