GAS CONNECTION
The gas connection is a 1/2" NPT Male
Thread. Copper can be used or other con-
nections approved by AG 604.
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
burner and/or valve servicing. Flare nuts for
copper lines are usually considered to meet
this requirement.
Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open fl ame for leak testing.
Note: Prior to any pressure testing of
the gas supply piping system
that exceeds test pressures of
3.45 kPa, this appliance must
be disconnected from the pip-
ing system. If test pressures
equal to or less than 3.45 kPa
are used then this appliance
must be isolated from the piping
system by closing its individual
manual shut-off valve during the
testing.

CO-LINEAR FLEX SYSTEM
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 fl ex running the
full length of the chimney. See the Flueing Arrangements chart in the "Flue Arrangement" sec-
tion for minimum and maximum fl ue lengths. See chart below for minimum distances from roof.
Periodically check that the fl ue is unrestricted.
Masonry chimneys may take various contours which the fl exible liner will accommodate. However,
keep the fl exible liner as straight as possible, avoid unnecessary bending.
The Air Intake pipe must be attached to the inlet air collar of the termination cap.
