4. Insert the liners through the fi restop maintaining the required
clearance to combustibles. Holding the air terminal (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, W573-0007
(not supplied) to the inside of the 5" liner approximately 1" from the
end. Slip the liner a minimum of 2" over the fi replace vent collar and
secure with 3 #8 screws.

1. Secure the terminal to the terminal extension plate (see fi gure
21).
2. Stretch the 5" diameter fl exible liner to the required length tak-
ing into account the additional length needed for the fi nished wall
surface. Slip the liner a minimum of 2" over the inner sleeve of the
air terminal and secure with
3 #8 screws. Apply a heavy
bead of the high tempera-
ture sealant W573-0002
(not supplied).
3. Using the 8" diameter
fl exible liner, slide over the
outer combustion air sleeve
of the air terminal and se-
cure 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
fl ange.
2. Stretch the 5" diameter fl exible 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 8" diameter fl exible
liner.
4. Thread the air terminal connector/
pipe assembly down through the roof. The air
terminal must be located vertically and plumb.
Attach the air terminal connector to the roof sup-
port, ensuring that a minimum 16" of air terminal
will penetrate the roof when fastened.
DO NOT CLAMP THE FLEXIBLE ALU-
MINIUM LINER.
Use only approved flexible liner kits marked:
"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.

5. Remove nails from the shingles, above and
to the sides of the chimney. Place the fl ashing
over the air terminal and slide it underneath the
sides and upper edge of the shingles. Ensure
that the air terminal connector is properly centred within the fl ashing,
giving a 3/4" margin all around. Fasten to the roof. Do not nail through
the lower portion of the fl ashing. Make weather-tight by sealing with
caulking. Where possible, cover the sides and top edges of the fl ash-
ing with roofi ng material.
6. Aligning the seams of the terminal and air terminal connector,
place the terminal over the air terminal connector making sure the
liner goes into the hole in the terminal. Secure screws provided.
7. Apply a heavy bead of weather-
proof caulking 2" above the fl ashing.
Note: Maintain a minimum 2" space
between the air inlet base and the storm
collar. Install the storm collar around the
air terminal and slide down to the caulk-
ing. Tighten to ensure that a weather-
tight seal between the air terminal and
the collar is achieved.
8. If more liner needs to be used to
reach the fi replace, couple them together
as illustrated in Figure 25. The vent system must be supported ap-
proximately every 3 feet for both vertical and horizontal runs. Use
noncombustible strapping to maintain a clearance to combustibles
of 1".

6. Using the 8" diameter fl exible aluminium liner, apply high tempera-
ture sealant W573-0002 (not supplied), slide a minimum of 2" over the
fi replace combustion air collar and secure with 3 #8 screws.
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.
Do not allow the inside liner
to bunch up on horizontal or
vertical runs and elbows. Keep
it pulled tight. A 1 1/4" air gap
between the inner liner and
the outer liner all around is
required for safe operation. A
spacer is required at the start,
middle and end of each elbow to ensure this gap
is maintained.
For safe and proper operation of the fi replace, fol-
low the venting instructions exactly.
All inner exhaust and outer intake vent pipe
joints may be sealed using either Red RTV high
temp silicone sealant or Black high temp Mill
Pac with the exception of the fi replace exhaust fl ue collar
which must be sealed using Mill Pac (not supplied).
1. Install the 5" diameter
fl exible liner to the fi replace.
Secure with 3 screws and fl at
washers. Seal the joint and
screw holes using the high
temperature sealant W573-
0007 (not supplied).
2. Install the 8" diameter
fl exible liner to the fi replace.
Attach and seal with high
temperature sealant W573-0002 (not supplied).
VERTICAL AIR TERMINAL INSTALLATION
NOTE: Eight (8”) inches is the minimum bend radius allowed for
the 8” diameter fl exible liner.
