It's not the flame that is yellow Pete. There is actually a yellow orangeish red dust or deposit on the gloryhole just above the doors. It was worse when we had the old gloryholes. It's also all over the tank area but our air sampling says alls ok. Very low airborne lead particals. Well under the legal limit. Could this deposit be from running the burner in a reduction state? Flame coming out the door.
