Flueing
This appliance is designed to be attached to two
co-linear aluminium ex pipes running the full length
of the chimney. The ue length must be a minimum
length of 2.44 m and a maximum of 10.7 m. See
chart for minimum distances from roof. Periodically
check that the vent is unrestricted.
Masonry chimneys may take various contours which
the exible liner will accommodate. However, keep
the exible liner as straight as possible, avoid
unnecessary bending.
The Air Intake pipe must be attached to the inlet
air collar of the adaptor.
Gas Connection
GAS CONNECTION WARNING:
Only persons licensed to work
with gas piping may make the
necessary gas connections
to this appliance.
1) If the appliance is to be installed into an existing
chimney system, thoroughly clean the masonry
replace.
2) The appliance is provided with an opening on
the right hand side of the control compartment.
The 9.5 mm exible gas hose provided needs
to be brought in from behind this opening.
Ensure all gas connections are tight.
3) Locate the center point where the vent will pass
through the chimney above the appliance. Move
the appliance into the exact location where it is
to be installed. Ensure that the Insert is level.

Gas Pipe Pressure Testing
During pressure testing of the gas supply piping
system at pressures equal to or less than 3.45
kPa, close the appliance's manual shut-o valve
to isolated it from the gas supply. Disconnect the
piping from the valve at pressures over 3.45 kPa.
The manifold pressure is controlled by a regulator
built into the gas control and should be checked
at the pressure test point.
1. Make sure the unit is in the "OFF" position.
2. Loosen the "IN" and/or "OUT" pressure tap(s),
turning counterclockwise with a 3mm wide at
screwdriver.

4. Turn the unit on with the remote or wall switch.
5. The pressure check should be carried out with
the unit burning and the setting within the limits
specied on the safety label.
NOTE
Screw should be snug, but do not over tighten.
NOTE
• To properly check gas pressure, both inlet
and manifold pressures should be checked
using the valve pressure ports on the valve.
6. When nished reading the manometer, turn o
the unit, disconnect the hose, and tighten the
screw (clockwise) with a 3mm at screwdriver.

Installation in Full Masonry Chimney
1. Measure and record dimensions to determine total ex liner length
requirements (see instructions below for details).
2. Carefully feed the liner down the chimney and out through the
damper. One person should feed the liner through the chimney, and
another person should pull the liner from the bottom.
3. After carefully feeding the Flex Liner down the chimney to the bot-
tom, form and angle to line up the Flex Liner with the vent opening
on the appliance.
Important: Do not let the ex liner sag below the level at which it will
connect to the appliance or connector. This could allow hot gas to
become trapped and potentially become a re hazard. The Flex Liner
path should always be sloped up toward the termination cap.
4. Temporarily secure the ex liner at the top of the chimney. Be sure
to leave 76 mm of ex above the existing chimney to allow for con-
nection to the termination cap (chimney plate and termination cap).
5. Repeat Steps 1-4 for second length of Flex Liner.
6. At the top of the chimney, slide the chimney plate over the two ends
of the Flex Liner and secure it to the surrounding masonry using
masonry anchor bolts. Before installing the chimney plate, run a
bead of non-hardening seal and between the chimney plate and the
masonry to prevent moisture from entering the chimney.
Note: Verify that there is sucient room to mount the chimney plate
on to the masonry. You must have a level surface in order to install the
chimney plate properly.
7. Add a bead of Mill-pack sealant to each collar on the Co-Linear
to Co-Axial adaptor. Attach the Flex Liner ends at the top of the
chimney to the Co-Linear to Co-Axial adaptor. Use four sheet metal
screws to connect each Flex Liner run to the Co-Linear to Co-Axial
adaptor.
8. Install termination cap.
9. Add a bead of Mill-pack sealant to each collar at appliance end.
Connect the Co-Linear Flex to the two outlets on the top of the
appliance using four sheet metal screws each. See the appliance
manufacturer's instructions for details. Make sure the Flex Liners
do not sag behind the appliance. Finally, move the appliance into
its appropriate place. Mount the Adaptor to the chimney plate using
sheet metal screws.
