    Boiler noise

    I have a Larrs Mini them 225 boiler (new install 4 months) it just recently started making a screeching wineing sound as the temperature reaches 150 degrees, it starts quietly and gets louder as the temperature increases and stops when the burner shuts off (set point 160) it is not coming from the pumps or blower fan (no noise with pumps running ; only with burner on at 150 degrees +) it seems to come from inside the boiler.

    I will have the original installer look at it but think he is not such a good boiler man.
    (any smart boiler men in lower Westchester ?)

    Any ideas on what it could be. I could try to post a recording.

    Thanks
