Proceed once the vent installation is complete.
Note : All gas connections must be contained within
the fireplace when complete.
1. The fireplace is designed to accept a ½” gas supply line.
The fireplace is equipped with a ½” manual shut-off valve, and
an 18” listed flexible gas connector.
2. The access to the gas inlet is
located on the right side of the outer
shell.
3. The flex connector and shut off
must all be within the outer shell.
4. When flexing any gas line, sup-
port the gas valve so that the lines
are not bent.
5. Check for gas leaks by brushing
on a soap and water solution. do not
use open flame.
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 vent-
ing 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 seal-
ant to the outer edge of the inner
sleeve of the air terminal. Slip a 4”
diameter coupler a minimum of ”
over the sleeve and secure using
3 screws.
4
. Apply high temperature seal-
ant to the outer edge of the of the
outside sleeve of the air terminal.
Slip a 7” diameter coupler over
the sleeve 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 6” of air terminal will
penetrate the roof when fastened.
The air terminal must be located
vertically and plumb.
6. Remove nails from the shin-
gles, 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, giv-
ing 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.
7. Apply a heavy bead of waterproof caulking inches
above the flashing. Slide the storm collar around the air ter-
minal connector and down to the caulking. Tighten to ensure
that a weather-tight seal between the air terminal and the
collar is achieved.
8. Continue adding rigid venting sections, sealing and
securing as above. Attach a 4” collapsed telescopic pipe to
the last section of rigid piping. Secure with screws and seal.
Repeat using a 7” telescopic pipe.
9. Run a bead of high temperature sealant around the
outside of the 4” collar on the fireplace. Pull the adjustable
pipe a minimum of ” onto the collar. Secure with 3 screws.
Repeat with the 7” telescopic pipe.
10. In the attic, slide the vent pipe collar down to cover up
the open end of the shield and tighten. This will prevent any
materials, such as insulation, from filling up the 1” air space
around the pipe.

vERTICAL vENTING INSTALLATION GAS INSTALLATION
Vertical terminations may display a very active flame. If this
appearance is not desirable, the vent exit must be restricted
using restrictor plate, W500-005. This reduces the velocity
of the exhaust gases, slowing down the flame pattern and
creating a more traditional appearance.
The plate has a series of holes to allow for adjustment.
Remove the two screws on either side of the exhaust collar
inside the firebox. Install the plate in the desired set of holes,
then replace the screws.
It is recommend to secure in the third set of holes which
causes the greatest amount of restriction for vent length
between 5 and 30 feet.
