A documented cause of ignition failure on Baltur and Ecoflam burners is the combustion head being out of position — pushed too far forward, it raises the air velocity at the barrel outlet enough that ignition becomes difficult or fails outright. This sits alongside the general causes of ignition failure (electrode, transformer, gas valve timing) as a mechanical detail specific to combustion head adjustment.
The relationship between combustion head position and ignition
According to Baltur's technical documentation, the combustion head's position inside the barrel is factory-set by the manufacturer, and the distance between the disk and the nozzle is set so that the atomised fuel spray leaving the nozzle doesn't wet the disk and cause sooting. When the combustion head is pushed forward, air at the barrel outlet accelerates enough that ignition becomes difficult.
The recommended approach when this happens is to pull the combustion head back until ignition occurs cleanly and the correct position is reached. This positioning needs to be exact, since it's what limits the air available at first flame to ensure safe ignition even under difficult conditions.
Other common causes of ignition failure
The causes covered in our general fault code guide apply equally to Baltur/Ecoflam burners:
| Cause | Explanation |
|---|---|
| Incorrect electrode setting | The gap between electrodes, or between electrode and nozzle, has drifted from the manufacturer's specified value |
| Weak ignition transformer | The transformer isn't producing a spark, or produces an insufficient one |
| Combustion head/disk position | As above, air velocity high enough to prevent ignition |
| Gas valve timing | Gas isn't reaching the ignition electrode at the expected time |
| Air setting on oil-to-gas switchover | On dual-fuel systems, cases where the combustion air damper set for oil operation shouldn't be changed; air volume may need re-setting when switching to gas |
What to watch on dual-fuel Baltur/Ecoflam systems
Baltur's manual notes that on a burner run on gas oil, the combustion air damper setting should not be changed; but when switching to gas, gas flow needs to be set to match the air volume that was set during oil operation. This is a concrete example of the "separate setting for each fuel" principle covered in our dual-fuel burner guide — failing to review the air setting during a fuel switchover can cause an ignition problem.
What you can check yourself, and what you can't
What you can do: note any sound heard during ignition, and any signs of smoke or smell, and pass this to the service provider.
What you shouldn't do: attempt to adjust the combustion head position, electrode setting or air/gas ratio yourself — these settings sit within manufacturer-specified tolerances and must be made using calibrated measurement.
Frequently Asked Questions
Why does ignition become difficult on a Baltur burner?
A documented cause is the combustion head being pushed too far forward — this raises air velocity at the barrel outlet and makes ignition difficult. Other common causes include electrode setting and ignition transformer issues.
How is the combustion head position corrected?
The combustion head should be pulled back until ignition occurs cleanly and the correct position is reached. This adjustment should be made using calibrated measurement, within the manufacturer's specified tolerances.
What should be checked during a fuel switchover on a dual-fuel Baltur/Ecoflam burner?
Whether gas flow needs re-setting to match the air volume that was set during oil operation.
Can I fix an ignition failure myself?
No. Settings such as combustion head position, electrode gap and the air/gas ratio require calibrated measurement and should only be adjusted by authorised technical personnel. ---
