We ran out of oil so the oil burner needs to be bled to restart. It's an American Standard Arco-Flame Oil Burner, Model DH-5F Series F-1 . I used to do it on my old burner in the house I used to live in but I can't figure out even where you bleed it from. I can't afford to pay anybody to do it. We put dieael in the oil tank because I can't afford that either. Can anybody tell me how to do it ?
