USING FLEXIBLE VENT COMPONENTS

Use only approved aluminum flexible liner kits
marked:
"Wolf Steel Approved Venting" as
identifi ed by the stamp only on the
Spacers are attached to the inner fl ex liner at predetermined intervals to maintain a 1-1/4" air gap to the outer fl ex liner. These
1. Cut or frame a hole in an exterior wall with a minimum
round or square opening of 11
fi restop spacer over the opening to the interior wall.
Secure the terminal to the terminal extension plate if required
(see fi gure 18). The cover plate of the GD-222R terminal is
13"x13" and will cover the 11 1/2" x 11 1/2" opening but if the
opening is made any larger - the terminal extension plate is
required.
2. Stretch the 4" diameter aluminum fl exible liner to the
required length taking 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 temperature
sealant.
3. Using the 7" diameter fl exible aluminum liner, slide over
the outer combustion air sleeve of the air terminal and secure
with 3 #8 screws. Seal as before.
4. Insert the liners through the fi restop maintaining the
required clearance to combustibles. Secure to the exterior
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 ad-
equately supported using either an
alternate method suitable to the
authority having jurisdiction or the
optional roof support. (Fig.a)
2. Stretch the inner aluminum
fl ex 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. (Fig.b)
3. Repeat using the outer aluminum
fl ex liner. (Fig.b)
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. (Fig.c) If the attic space is
tight, we recommend threading
the Wolf Steel vent pipe collar or
equivalent loosely onto the air
terminal assembly as it is passed
through the attic.

5. Apply a heavy bead of the
high temperature sealant, (W573-
0007 not provided), to the inside of
the 4" 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.

5. Remove nails from the
shingles, above and to the
sides of the chimney. Place
the fl ashing over the air
terminal connector leaving a
min. 3/4" of the air terminal
connector showing above
the top of the fl ashing. Slide
the fl ashing 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 ashing with
roofi ng material. (Fig.c)
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 with the three screws provided. (Fig.c)
7. Apply a heavy bead of weatherproof caulking 2 inches
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 connector and slide
down to the caulking. Tighten to ensure that a weather-tight
seal between the air terminal connector and the collar is
achieved. (Fig.c)
