5. 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 centred within the flashing,
giving a /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.
6. Apply a heavy bead of weatherproof caulking  inches
above the flashing. Slide the storm collar around the air termi-
nal and down to the caulking. Tighten to ensure that a weather-
tight seal between the air
terminal and the collar is
achieved. Attach the other
storm collar centred be-
tween the air intake vent
pipe and the air exhaust
slots onto the air terminal.
Tighten securely. Attach
the vertical rain cap.
Spacers are attached
to the exhaust liner at
predetermined intervals
to maintain a 1-1/4" air
gap to the air intake vent
pipe. these spacers

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 to the outer edge of the
exhaust of the fireplace. Attach the first vent component
and secure using  self tapping screws. Repeat using air
intake liner.
3. Holding the air terminal (lettering in an upright, readable
position), insert 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 (not supplied).
the air terminal mounting plate may be recessed into
the exterior wall or siding by 1½", the depth of the return
flange.

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  feet for both vertical and
horizontal runs. Use noncombustible strapping to maintain a
clearance to combustibles of ".
FIREPLACE VENT CONNECTION
1. Install the exhaust to the fireplace. Secure with 3 screws
and flat washers. Seal the joint and screw holes using W573-
0007 0.oz tube of high temp sealant (not supplied).
2. Install the air intake vent pipe to the fireplace. Attach
and seal the joints.
EXTENDED HORIzONTAL AND CORNER
AIR TERMINAL INSTALLATION
1. Follow the instructions for "Horizontal Air Terminal Instal-
lations", items  to .
2. Continue adding components alternating inner and outer
venting. Ensure that all exhaust venting and elbows have suf-
ficient vent spacers attached and each component is securely
fastened to the one prior. Attach the exhaust adjustable vent
to the vent run. Repeat using a air intake vent pipe adjust-
able vent. Secure and seal as before. To facilitate completion,
attach exhaust and air intake vent pipe couplers to the air
terminal.
3. Install the air terminal.
see item 3 of the horizontal air
Terminal Installation. Extend
the exhaust adjustable vent;
connect to the air terminal as-
sembly. Fasten with self tapping
screws and seal. Repeat using
the air intake vent pipe adjust-
able vent.
