The light-up cycle proceeds normally with HV sparks between light-up electrode and earth Does not light up after several attempts - Filter ahead the reducer clogged - Injector clogged or partially clogged - Ill-suited injector - Gap between light-up electrode is too wide - Electrovalve jammed in ‘off’ position - Clean the filter - Clean the injector - Replace injector - Adjust gap - Replace the electrovalve The light-up cycle proceeds normally with HV sparks between light-up electrode and earth The burner lights up but goes out within 4 seconds upon light-up - Ill-suited injector - Ionisation electrode positioned in relation to burner or earth - Poor earthing on safety box - The safety box is defective (ionisation control is too slack) - Phase-neutral inversion - Neutral impedance - Replace the injector - Reposition the electrode - Clean point contact - Replace the control box - Connect properly - Fit in an isolation transformer
