    why not?

    I have seen them often.Sometimes with end switch to keep the burners off until damper is open. You may need a smaller opening that is not dampered for the pilots. And with three water heaters plus a boiler it would probably open for alot of the time anyways(something always firng). And if all else fails, insulate the floors !-)

    combustion air issue

    Thanks for the input ,bro. my thoughts pretty much the same.i would insulate the floors & put in a 12" x 12 "duct vent w/ fusible link damper and return bend outside case closed . was hoping the experts would have some more options for me but no looka too good !!

    Against residential code?

    In commerical buildings interlocked motorized dampers are not to code in some municipalities (in Colorado). {Edit: They must be fixed open louvers.} Not sure about residential.

    Regardless....here is a resource for nice intake units to do what you want:

    Inter Lock.

    It HAS to be inter locked with all Fuel consumption equipment. Car dealerships for example. We see them all the time.
