I'm installing two Burnham Alpine condensing boilers in multifamily. I know that distance between air intake and exhaust must be more than 12 inches. I wonder if there's a minimum distance between two boiler's intake and exhaust? I'm in the state of MA，Thank you!

    Check your local codes. There may be something in there. Otherwise, so far as I know, the two intakes can be close together, and likewise the two exhausts -- so long as the exhaust to intake spacing is adequate.

    Not sure about MA as the laws of physics are slightly different there ;) . In most areas the manufactures installation instructions take precedence. It is a good idea to separate the intakes and exhaust as far as you reasonably can. Cross contamination will destroy your boilers.
