If you don't know what or where that is, it is probably time to call

I agree with Paul's advice. I want to add one more thing. The boiler was
recently installed you say? I would think the installer would come back and
take care of any problems that may show up. Try the bleeding as that is
simple and free, but don't hesitate to ask the installer for help. He may
have bled the system originally, but it just needs more or some sort of
adjustment.
