Are these boilers positive pressure?

The cleaning ports are on the front. Are there any other vents to vac that I may be missing?

    Yes, this boiler is positive pressure. There are passageways between the combustion chamber and heat exchanger that may need to be cleaned. I've only cleaned them out once on a boiler that had clogged with soot. My Biasi is about nine years old and I have never needed to do this. I clean the combustion chamber every time I clean the boiler though
