7. 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.
8. Apply a heavy bead of
weatherproof caulking 2”
above the flashing. 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 collar is achieved.

1. Install the 4” diameter flexible vent pipe to the fireplace.
Secure with 3 screws
and flat washers. Seal
the joint and screw
holes using the high
temperature sealant
W573-0007 (not
supplied).
2. Install the 7”
diameter flexible vent
pipe to the fireplace.
Attach and seal the
joints using high

USING RIGID VENT COMPONENTS
HORIZONTAL AIR TERMINAL INSTALLATION
The vent system must be supported approximately every 3 feet
for both vertical and horizontal runs. Use Wolf Steel vent spacers
or equivalent every 3 feet and either side of each elbow to
maintain the minimum 1¼” clearance between the outer and inner
vent pipes. Use Wolf Steel support ring assembly or equivalent
noncombustible strapping to maintain the minimum clearance to
combustibles for both vertical and horizontal runs.
All inner exhaust and outer intake vent pipe joists may be
sealed using either red RTV high temp silicone sealant or
black high temp Mill Pac with the exception of the fireplace
exhaust flue collar which must be sealed using Mill Pac (not
supplied).
EXTENDED HORIZONTAL AIR TERMINAL
INSTALLATION
1. Move the
fireplace into
position. Measure
the vent length
required between
terminal and
fireplace taking
into account the
additional length
needed for the
finished wall
surface and any 1¼” overlaps between venting components.
2. Apply high temperature sealant W573-0007 (not supplied) to
the outer edge of the 4” inner collar of the fireplace. Attach the
first vent component and secure using 3 self tapping screws.
Repeat using 7” piping.
3. Holding the air terminal insert the terminal into both vent pipes
with a twisting motion to ensure that both the terminal sleeves
engage into the vent pipes and sealant. Secure the terminal to the
exterior wall and make weather tight by sealing with caulking
W573-0002 (not supplied).

3. Install the air terminal. See
item 3 of the Horizontal Air
Terminal Installation. Extend the
4” telescopic sleeve; connect to
the air terminal assembly. Fasten
with self tapping screws and seal.
Repeat using the 7” telescopic
sleeve.

1. Follow the instructions for “Horizontal Air Terminal Installa-
tions”, items 1 to 3.
2. Continue adding components alternating inner and outer
venting. Ensure that all 4” venting and elbows have sufficient vent
spacers attached and each component is securely fastened to
the one prior. Attach the 4” telescopic sleeve to the vent run.
Repeat using a 7” telescopic sleeve. Secure and seal as before.
To facilitate completion, attach 4” and 7” couplers to the air
terminal.
1. Move the fireplace into position.
2. 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.
3. Apply high temperature sealant
W573-0007 (not supplied) to the outer
edge of the inner pipe of the air
terminal connector. Slip a 4" diameter
coupler a minimum of 2" over the pipe
and secure using 3 screws.
4. Apply high temperature sealant
W573-0007 (not supplied) to the outer
edge of the of the outside pipe of the air
terminal connector. Slip a 7" diameter
coupler over the pipe and secure as before.
Trim the 7" coupler even with the 4" coupler
end.
5. Thread the air terminal pipe assembly
down through the roof support and attach,
ensuring that a minimum 16" of air terminal
will penetrate the roof when fastened. 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. The air terminal must be located
vertically and plumb.
6. Remove nails from the shingles, above and to the sides of the
chimney. Place the flashing over the air terminal and slide it
underneath the sides and upper edge of the shingles. Ensure that
the air terminal is properly centered within the flashing, giving a
3/4" margin all around. Fasten to the roof. Do NOT nail through
the lower portion of the flashing. Make weather-tight by sealing
with caulking. Where possible, cover the sides and top edges of
the flashing with roofing material.
