Whistling steam boiler

I have e really old steam boiler(name tag fell off)..when it's starting up cold in the morning it whistles and not really sure why...it's eventually going to get replaced but for the mean time im curious why it is producing this sound....any ideas?

    it could be the main air vent on the return allowing air to escape from the main pipes. my old american standard would whistle as the gas started into the tubes.

    make sure that when it is replaced, the installer measures the heat capacity of all the radiators, and not just the heat loss of the building!

    if your main vent is whistling, it is too small.--nbc
