GAS CONNECTION
The gas connection is a 1/2" (13mm) NPT Male
Thread. Copper can be used or other con-
nections approved by AG 604.
When using copper or flex connectors use
only approved fittings. 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 flame 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 dis-
connected from the piping sys-
tem. If test pressures equal to or
less than 3.45 kPa are used then
this appliance must be isolated
from the piping system by clos-
ing its individual manual shut-off
valve during the testing.
VERTICAL TERMINATION WITH
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 flex running the
full length of the chimney. See the Fluing Arrangements chart on page 9 for minimum and maximum
flue lengths. See chart below for minimum distances from roof. Periodically check that the flue
is unrestricted.
Masonry chimneys may take various contours which the flexible liner will accommodate.
However, keep the flexible liner as straight as possible, avoid unnecessary bending.
The Air Intake pipe must be attached to the inlet air collar of the termination cap.
