Rattling Spirovent

I had a spirovent installed on my boiler a few years ago. It just started making a load rattling noise. Any ideas what might be causing it?

try bleeding out your system to see if it stops

Bleeding the air out. I'll try it, but isn't that what the spirovent is supposed to do?

Rattling like that could be caused by the float assembly acting up.... I'd check that 1st.
