Combustion air for power burner?

Hoping to dramatically tighten up the envelop in my boiler room this summer. Heretofore, a large, leaky barn-door led directly to a (defunct) coal bin under the front porch. I'll also be replacing a woefully inadequate door under our Belco doors.

We recently installed a new steam boiler with a Carlin EZ gas burner. I asked our installer at the time about the effect insulating might have on combustion and his solution was essentially "don't insulate the boiler room."

I wasn't going to try to argue the point. anybody know if there's an aftermarket solution here to supply the power burner with combustion air? The house will be by no means air tight, but I'd rather be safe.

    There is

    it's a "boot" that will fit on the burner's air intake, to which a duct connects going to the outside. That's one of the things we like about the EZ-Gas.

    Where is it?

    I looked all over Carlin's website and couldn't find anything like this, and I don't seem to be searching for the right thing on the web. Can you point me to this thing?

    when in doubt, call the manufacturer.

    for the record

    for the record:

    according to NFPA 31

    1 cu foot of airspace will support 20 BTUs.

    For example:

    30'x16'x8' room = 3840 cu feet

    3840 cuft x 20 BTU = 76800 BTU

    So this room would only support a 76800 appliance if it was completely buttoned up and air tight. (don't forget to adjust for downfiring)

    Actually, I can't figure out why intake air boots aren't installed on ALL boiler systems. 

    Also, efficiency would be improved by using cold air from outside.

    screw it, put a supercharger on it.
