hi I have a riello rbd burner. It was airlocked after oil ran out. I managed to bleed it by opening 2 different screws with 4 mm allen key. its working on its own now however it comes on for 5 min and then goes off for a few minutes and back on for 5 min. Is this normal? I remember it used to come on for longer.
