Flue Termination
The Flue Terminal shall be located
so that wind from any direction is not
likely to create a downdraught in the
flue. A Flue Cowl, AGA approved to
AS4566 (AG604) must be fitted to the
end of the flue pipe. The minimum
flue length must not be shorter than
3.5 metres. Maintain a minimum of
500mm from the bottom of the flue
cowl to the nearest part of the roof
if the flue cowl is at least 1m from a
neighbouring structure. If less than
1m, the flue terminal must be located
at least 500mm above that structure.
Refer to AS5601 - 2004 (AG601)
sections 5.13.6.2 and 5.13.6.4 to
ensure that the location of the flue
terminal fully complies for installations
with a trafficable roof, a chimney,
another flue terminal or near any
openings into a building.

HOW TO SET GAS PRESSURES

It is critical that all gas products be properly installed. Proper installation must include:
1. Vent configuration in line with requirements stated in manual.
2. Vent cap/terminal meets all clearance stated in manual.
3. Gas pressure is checked and adjusted at the time of installation.
Note: Pressures must be checked and adjusted to the correct specified
pressure otherwise warranty will be invalid.
The pressure is measured on the gas valve and the regulator can be adjusted by turning the
screws on the gas valve located either side of the pressure test points. (Refer to diagram
in installation manual).
If the gas pressure is not checked it can lead to “sooting”, “delayed ignition” or performance
issues. Proper gas outlet pressure ensures that the fireplace is operating within the
standards it was tested.
Ensure that the gas pressure does not change when other gas appliances in the home are
activated. If the “inlet” pressure into the gas fireplace was to change when other appliances
are activated this will cause the pilot flame to reduce in size, drop the millivolt output and
possibly cause the unit to shut down.
Reminder: The inlet pressure of the gas fireplace is an unregulated pressure. Only the
outlet pressure is held by the regulator located on the front of the gas valve.
Once installation is complete, it is imperative to do a smoke test to ensure that the gas
fumes are consistently drawn up the flue.
* This page does not take the place of the manual for each individual product, but is merely
stressing the above points. Always read and understand the manual prior to installing
any fireplace product.
Thank you for ensuring that our products are installed and operated safely.
Pressure “taps” are located at the face of the valve. There are two taps, one marked “ IN ”
and the other marked “ OUT ”.
- To check gas pressure simply turn the brass screw located in the “ OUT ” tap
counter clockwise several turns.
- Hook up a manometer tube to the “ OUT ” tap.
- Turn the fireplace on and turn the flame adjustment (if applicable) to high. The
outlet pressure should be set to the pressure stated on the
compliance plate on the floor of the unit.
- Turn the fireplace off.
- Remove manometer tube from “
OUT ” tap.
- Tighten the screw by turning clockwise until snug.
- Soap water test to check for gas leaks.
