    whistle

    I have a Utica gas boiler, it has been in operation for 12 years. For no apparent reason it started whistling this spring. I have adjusted gas pressures and checked air band settings,adjustested manifold pressure to no avail. It starts out intermittenly then will turn into a constant moan the lomger it runs.it is a utica MGB150 on propane any suggestions??
