    You need to provide more information. Possibly, posting the noise.

    Is the noise coming from the blower or combustion ?

    There was an error rendering this rich post.

    Oil or gas fuel? What type of burner? Pictures?

    That's often like trying to describe a squeak in your car.

    FWIW, I've seen circulators make noise that travels through the whole system making it hard to find. A small section of rubber hose used like a crude stethescope can often help find noises. While it's acting up, put the hose on the circulator(s), burner motor,etc.

    This is a fire tube condensing boiler. Typically the noise is from the combustion not being set correctly with a digital combustion analyzer or in some cases the gas line being undersized. Nothing we can do to help you with a combustion issue but if you post pictures of the boiler and piping we can see if the gas line is a possible problem.

    Nat gas or LP? A mechanic's stethoscope that you can get at an auto parts store would help pinpoint the noise. Any valves not fully open?
