    Dunkirk Gas boiler starts up then shut off
    I have a dunkirk Gas boiler. It has been working sporadically lately. Specifically it fires
    And burners flame on then shut off. I'll turn off power switch and repeat the process
    And the results are the same. My neighbor came over and bled the system ,removing
    Sediment that was showing in glass water level tube. It worked all right for a day and the
    Problem returned.
