Adjusting the Pilot Flame
When lit, the pilot should produce a flame 10 – 13mm
vertically high that impinges evenly across both
thermopiles.
The pilot flame can be adjusted by rotating the pilot
adjustment screw on the gas valve which will alter the
gas pressure to the pilot. Unscrew and remove the
outer cap and turn the internal screw clockwise to
decrease the pilot flame or anti-clockwise to increase
the pilot flame.
If the pilot flame cannot be adjusted, is uneven or
splutters, the gas supply and pressure should be
checked as should the pilot injector to ensure it is clean
and not blocked with foreign matter.
Adjusting the Ignition Plug Gap
The ignition plug gap should be set at 3mm. This gap is
measured between the ignition plug probe and the
closest point on the hood of the pilot. The ignition plug
gap can be adjusted by gently bending the ignition plug
probe the required direction with a pair of long nose
pliers. Be careful not to crack or break the ceramic body
of the ignition plug whilst adjusting.
Gas Valve Safety Shutdown Test
The gas valve safety shutdown test should be performed whenever the gas valve is
replaced, adjusted or gas type converted.
To perform the gas valve safety shut down test follow the procedure outlined below.
1. Light the log fire by following steps 1 – 6 of the lighting instructions on page 12.
2. Rotate pilotstat knob to the pilot position. The main burner should extinguish
however the pilot should remain lit.
3. Extinguish pilot flame by isolating the gas supply to the log fire.
4. When the pilot flame extinguishes, immediately restore the gas supply to the log
fire. Gas flow to the pilot should cease within 30 seconds from pilot outage (gas
valve safety shut off activated).
5. Relight log fire and operate through one complete cycle to ensure all controls
operate correctly including remote controller operations.
Fault Indication
Both log fires utilise a simple form of fault indication which is provided by the gas valve
LED. As mentioned previously the gas valve will blink when lighting the pilot and once after
every command from the remote control, these are not fault indications.
It should be noted that failure codes may occur anytime after the pilot has been lit and in
the event of multiple failure codes the first failure code will be followed by a three second
delay then the second failure code will be displayed.
