Because of the extreme heat this fireplace emits, the mantel clear-
ancesare critical. Combustiblemantelclearancesfromtop ofdoorframe
are shown in the diagram below. Mantel may be installed anywhere in the
shaded area or higher.
Note: A non-combustible mantel may be installed at a lower
height.
Note: Ensure the paint that is used on the mantel and the facing is
“heat resistant” or the paint may discolour.

THE APPLIANCE MUST NOT BE CONNECTED TO A CHIMNEY
FLUE SERVING A SEPARATE SOLID FUEL BURNING APPLIANCE.
This appliance is designed to be attached to two 3" (76mm) co-linear
aluminium flex running the full length of the chimney. The flue length
must be a minimum length of 8' (2.44m) and a maximum of 35' (10.7m).
Periodically check that the vent is unrestricted.
Masonry chimneys may take various contours which the flexible liner will
accommodate.However,keepthe flexiblelinerasstraightaspossible,
avoid unnecessary bending.

GAS CONNECTION
GAS CONNECTION WARNING:
Only persons licensed to work with gas piping may
make the necessary gas connections to this appliance.
1) Whentheapplianceistobeinstalledintoeitheranexistingmasonry
chimney system or factory built fireplace, thoroughly clean the
chimney before installation.
2) A 3/8" NPT gas supply pipe must be brought near the inlet hole.
The valve inlet is on the right side of the unit.
3) Locatethecenterpointwheretheventwillpassthroughthechimney
above the appliance. Move the appliance into the exact location
where it is to be installed. Ensure that the Insert is level.
NOTE: This unit is equipped with a heat sensor thermodisc which
will prevent the blower from operating until the unit reaches the
correct temperature.
5) Install flashing onto top of masonry cap, securing with sealant and
mechanical fasteners
6) Insert both liners into chimney, passing through the damper open-
ing.
7) Install termination cap securing with supplied screws to flashing.
8) Connect the marked end of the liner to the exhaust collar of the
vent connector plate marked with an "E", seal connection with high
temperature silicone. Secure with gear clamp or screws.
NOTE:
1) Final gas connection should be made after unit is in place to avoid
damage to the liner when pushing the unit into position.
2) Mill-pac may be used instead of high temperature silicone and
screws may be used instead of gear clamps at connections of liner
to inlet and vent collars.
9) Connect the 2nd liner to the intake collar, seal connection with high
temperature silicone. Secure with gear clamp or screws.
10) Align vent connector plate with guides on unit.
11) Slide unit into masonry opening, while ensuring that the slots at the
rear of the connector plate mates up with the hold down plate on
the unit.
12) Secure with screw.
FLUE LINER
INSTALLATION
1) Cut the flex liner as required.
2) Mark the end of one liner with an "E" to indicate Exhaust.
3) Connect the other end of the above liner to the exhaust side of the
termination cap, seal connection with high temperature silicone.
Secure with gear clamp or screws.
4) Connect the 2nd liner to the inlet side of the cap, seal connection
with high temperature silicone. Secure with gear clamp or screws.

GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas sup-
ply piping system by closing its individual manual
shut-off valve during any pressure testing of the
gassupply pipingsystem attest pressuresequal
to or less than 1/2 psig. (3.45 kPa). Disconnect
piping from valve at pressures over 1/2 psig.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
at the pressure test point.
Note: To properly check gas pressure, both
inlet and manifold pressures should be
checked using the valve pressure ports
on the valve.
1) Make sure the valve is in the "OFF" position.
2) Loosen the "IN" and/or "OUT" pressure tap(s),
turning counterclockwise with a
1/8" wide flat screwdriver.
3) Attachmanometerto"IN"and/or"OUT"pressure
tap(s) using a 5/16" ID hose.
4) Lightthepilotandturnthevalveto"ON"position.
5) The pressure check should be carried out with
theunitburningandthesettingshouldbewithin
the limits specified on the safety label.
6) When finished reading manometer, turn off the
gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" flat screwdriver.

GAS LINE
INSTALLATION
Since some municipalities have additional local
codes it is always best to consult with your local
authorities and the CAN/CGA B149 installation
code.
For USAinstallations follow local codes and/or the
current National Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use only
approved fittings. Always provide a union so that
gas lines can be easily disconnected for servicing.
Flare nuts for copper lines and flex connectors are
usually considered to meet this requirement.
NOTE: A shutoff / dante valve should be sup-
plied in or near the unit (or as per local codes)
for ease of servicing this appliance.
IMPORTANT: Always check for gas leaks with
a soap and water solution or gas leak detector.
Do not use open flame for leak testing.
The gas line is located on the right hand side of
the appliance.
