Appendix 6: Diagnosis diagram

Subject to change because of technical improvements
Problem
No spark
Spark but no ignition
When ignition button is released, pilot flame goes out
Main burner does not ignite
Whistling between high and low setting
Disrupted flame effect
Gas smell
Smell of combustion gases in room
Appliance goes out
Remote control does not work
possible cause
Power supply cable is loose
Power supply short circuit
Spark plug broken
Piezo ignition faulty
No gas
Air in pipelines
Gas pressure too high
Gas pressure too low
Pilot flame nozzle or pilot flame pipe
blocked
Incorrect pilot flame nozzle
Thermocouple not warm enough yet
Thermocouple is not in the pilot
flame
possible solution
(*) = have installer carry out this
action
Check the connectors.
Repair the short circuit. Do not lay the igni-
tion cable next to metal surfaces as this
weakens the spark.
Replace the spark plug (*).
Replace the piezo ignition (*).
Check that the gas valve is open.
Flush the pipe by holding the ignition button
pressed for a longer time.
Check the supply pressure or inform the
gas supplier (*).
Check for a local blockage of the gas sup-
ply, for example due to accumulation of dirt.
Check the supply pressure or inform the
gas supplier (*).
Clean the parts (blow through) or replace
the nozzle (*).
Install the correct pilot flame nozzle (*).
Keep the ignition button pressed longer.
Position the thermocouple correctly in the
flame (*).
