Does air eventually move through the pump?

I bled my pump after I changed the filter into a small bottle. The boiler is running now but from what I’ve read I need to bleed at least a half gallon while a tube is hooked up To the bleeder.

The tank and boiler are close and level to one another and it’s running fine I’m just wondering if I should go and buy some tubing and drain a half gallon out?

    And can the oil filter be on a slight angle where it mounts? The bracket is kind of bent downward a little but not bad. It just made the filter slightly in an angle

    Angle of the filter is just a bit sloppy -- won't affect the operation. Ideally one would bleed the pump into a clear container until one saw all the bubbles stop. There isn't really a volume required.

    It is sloppy it bother me but the bracket won’t bend. I’ve read so much about air bubbles in oil after filter change and I was hoping I don’t have to bleed it a different way. Thanks

    Proper bleed is a power vacuum bleed. Hose in can, submerged in oil, until no more air.
    Unless you have a 2 pipe, with bypass plug installed, then you don't have to bleed. But too much air, vacuum leak, or high vacuum will still cause a lockout.

    It is one line from the tank to a valve and through a filter to the burner motor

    Is the burner running?
    You've got three different but the same threads going.
    If it's running, leave it.
    If you don't already have one, get a service agreement with a reputable contractor who is familiar with Buderus and Riello.
    What's the operating control? Logamatic 2107 or aquastat?

    I am in Maine in the middle of nowhere. There aren’t any dealers let alone for this type of equipment.

    I’m on my own basically. Besides the internet and you tube to help me.
    There is a guy that does tuneups as part of the oil delivery plan. He tested it yesterday. I don’t know what you mean by controls? There’s a box on the side and on top. The one in the side is black and the other is grey.
