8. Sparks, ignites on low flame
then extinguishes after 10
seconds. Continues to spark
during flame presence.
9. No gas to burner.
10. Appliance lights but goes
into lockout.
11. Fuse blowing.

• Check that the wall socket to the appliance has
correct polarity. Do not use an extension cord. Check
polarity in the electrical supply lead to appliance.
• Check that the sense electrode is in the flame.
• Check that appliance is earthed correctly. A check
between the earth pin on the plug and an unpainted
part of the appliance should see a resistance of
0.1 ohms.
• The gas valve should open at the same time as the
igniter sparks. If there is no gas to the burner when
this occurs check the solenoid coils for continuity.
• Check that the gas pressure is present at the test
point when the spark is being generated.
• Check that there is gas to the inlet of the gas control.
• Test the flame for correct ionisation signal. Connect a
multimeter in series with the flame rod and set the
function to measure micro-amps. The module will go
into lockout if the flame current sensitivity is less than
0.5 micro-amps. The approximate signal strength on
high flame is about 10 micro-amps and on low
4 micro-amps. The signal strength will fluctuate but
should be greater than 1.5 micro-amps at all times.
Take precaution because the ionisation probe can
have a high negative voltage and can cause shock.
• If the fuse continues to blow check the solenoid coils
for signs of them being shorted.
• Check the fan and wiring for short circuit.

Connections

Terminals 5, 6 and 7 at the module 12 way connector
are bridged.
Terminal 10 at the module 12 way connector is the ac-
tive supply via the red wire.
Terminal 11 at the module 12 way connector is the neu-
tral supply via the blue wire.
Terminal 12 at the module 12 way connector is the earth
connection via the green/yellow wire.
Terminal 12 at the module 2 way connector is the neutral
connection via a brown wire which is joined into the
rectifier cable then into the 8 way switch connector blue
wire.
Terminal 14 is an active connection at the module 2 way
connector via a white wire into the 8 way switch connec-
tor. This is active only when the flame is sensed.
