The burner manifold directs gas from the gas valve to the front and rear burner injectors.
The burner manifold has an aeration shutter which controls the air gas ratio for delivery to
the injectors. The aeration shutter is preset and the position remains the same for both gas
types.
Injectors
Both log fires have three injectors (pilot, burner front and burner rear). The pilot injector
delivers gas to the pilot whilst the burner injectors deliver gas from the burner manifold to
the burner for combustion. Injector size is dependent upon gas type (refer to „Gas Type
Conversion Procedure‟ on page 51 for more information).
Burner
The burner is where combustion occurs. The gas valve supplies gas to the burner manifold
which in turn supplies gas to the burner via a front and rear injector. The gas is then
injected into the burner and ignited by cross lighting from the pilot flame.
Gas valve
A Honeywell RV8310D gas valve is utilised for burner control and provides manual piezo
ignition, flame modulation, flame monitoring and LED indication. It also allows for remote
control of temperature, fan and flame appearance via a hand held remote control unit. The
gas valve is available in NG or Propane and is gas type convertible (refer to „Gas Type
Conversion Procedure‟ on page 51 for more information).
Gas Valve Features
1. Pilotstat knob: The pilotstat knob is used to light and turn the log fire on and off (refer
to „Lighting Instructions‟ on page 12 for more information).
2. Modulating motor: The modulating motor
drives the gas valve open or closed in
seven stages ranging from 0 – 6, with 0
being fully closed and 6 being fully open.
3. Piezo Igniter: When pushed, the piezo
igniter creates a high voltage which is sent
to the ignition plug. The high voltage is
created when a spring loaded striker is
manually activated striking an internal
crystal. The high voltage jumps (arcs)
across the ignition plug gap trying to find a
path to earth and ignites the gas flowing
through the pilot injector.
4. Local/Remote switch: This switch is set on „Local‟ when lighting the log fire. After
lighting the log fire and turning the pilotstat knob to „on‟ it may be left on „Local‟ or
switched to „Remote‟. If left on „Local‟ the gas valve will operate on full flame (gas valve
fully open) and full fan speed with only the fan speed able to be adjusted by the remote
controller. If set on „Remote‟ the remote controller can be used to adjust the flame
height (gas valve modulation) and fan speed.
5. LED: The LED will flash to indicate gas valve and/or remote control operation and will
also indicate a thermopile or gas valve fault.
