- If the ignition transformer produces a spark (click), but
there is no spark at the spark plug, first check the ignition
cable by removing it from the spark plug and making
a connection approx. 3-5 mm from earthed material. If
there is a spark between the connection and the material,
there is no fault in the ignition cable, and the fault lies
in the spark plug which must be replaced. If there is no
spark, but a ticking is heard from the ignition transformer,
the fault is in the ignition cable.
- If there is only one single spark (the lamp flashes once)
this is due to the effect on the spark plug of dampness or
condensation. The spark plug/ignition cable is then faulty,
and must be replaced.
NOTE! When this fault occurs, the boiler can be jump-
started by removing the ignition cable from the lighter and
attaching it 3 - 5 mm from the connection pin so that it
forms an extra spark gap. Start the boiler in accordance
with the instructions. Remove the fuse and connect the
ignition cable when the boiler starts. Replace the fuse.

Cause
:
- The ignition cable has loosened at the connection to the
lighter or the spark plug.
- Break in the ignition cable.
- Ignition electrode not in centre of pilot flame.
- Pilot flame too small.
- Fault in ignition transformer.
Remedial action:
- Check that the ignition cable is correctly connected or
replace the ignition cable.
- Adjust the ignition electrode so that it is in the centre of
the pilot flame.
- Check the gas supply and nozzle in the pilot burner.
- Replace the ignition transformer.

Cause :
- Micro-switch wrongly adjusted.
- Thermostat knob turns too easily.
- Thermostat knob turns too slowly.
Remedial action:
- Adjust the micro-switch in accordance with chap. 6:10.
- Check that there is an o-ring in the groove on the shaft
of the thermostat knob, and that there is not too much
grease on the shaft and in the knob hub, wipe any excess
away.
- If the knob feels springy (does not remain in the position
in which it is released), lubricate the o-ring very sparingly
with grease.
- Replace the thermostat knob.
nOtE! When the thermostat knob is removed, it must be
re-fitted in the same position, otherwise the temperatures
setting will change.

This guide to general fault-finding should be useful in
rapidly establishing where in the heating system the fault
may lie. This saves time in fault-finding. For more detailed
fault-finding, see sections 5:2 - 5:15.
Fault Possible fault in
Boiler does not start Gas supply, fuse,
ignition system
Boiler/electrical cartridge Temperature-settings,
not warm boiler thermostat, electri-
cal cartridge thermostat
Boiler/electrical cartridge Circulation pump, air in
warm, but no heat in the heating system,
caravan or boat warm water heater
Boiler/electrical Temperature-settings
cartridge boiling boiler thermostat, electri-
cal cartridge thermostat
Noise in circulation pump Liquid level, air in the
12/230 V system, foreign object in
pump housing, pump
motor, paddle wheel
Uneven temperature in Regulating equipment
the caravan or boat room therm., connections
Too little warm water System temp, circulation
pump, water-flow

Cause:
- Voltage to ignition transformer absent or too low.
- Fault in ignition transformer.
- Insulation fault on spark plug.
- Insulation fault on ignition cable.
- Fouling/dirt on spark plug.
Remedial action:
- Check that there is 12 V voltage on the boiler connection
block between pins 1 red (+) and 4 black (-).
- Check that the fuse in the control panel is intact.
- Check that the micro-switch trips when the thermostat
knob is turned to the ignition position. Use a voltmeter to
measure the voltage between the yellow (+) and black (-)
cables on the ignition transformer. This must be > 9 V.
- Check the ignition transformer by removing the ignition
cable from the connection and turning the thermostat
knob to the ignition position. The ignition transformer
should then produce a spark (click) and the indicator
lamp should flash continuously. If not, the ignition trans -
former is faulty and must be replaced.
