    EVERY boiler in a forced flow hot water system requires a circ.

    If it's an old gravity flow system with a boiler designed for gravity flow, that's a different animal.

    If you meant does it come packaged with one, I believe it comes with a TACO 007, no flow check.

    I think the question is does it require a circ pump?
    A gravity system today would be interesting.

    It does. There is too much resistance inside the boiler to allow gravity flow.

    Most likely, it's air bound. That's assuming it's piped correctly. If it's a monoflo system, it can be extremely difficult to get all of the air out.

    You are going to need to post a lot more information about your system.
    Is the house radiators or baseboard originally?
    Does it have a pump now?
    Pictures of what you have and what you added would help a lot.
