A Heavy oil Burner (200 secs and above) will have a cut off valve behind the nozzle because heated oil has to flow around the HP circuit prior to light up, it is likely that the cut off valve is faulty

Try contacting the Riello Service agent in Greece, they should be able to help - Riello burners are diffrent country by country so a UK site will not be able to be specific not knowing the spec for greece
