It is entirely possible that you have a couple of boilers with problems that came right from the factory. It is also entirely possible that these aren't the correct boilers for your application, and/or that they've been installed incorrectly. There's no way to really determine the cause of your problem without seeing it. Were the "licenced heating contractors" guys who do hot water heating as their main gig, or were they forced air/plumber types dabbling in the hot water heating field? (There's more to this than just screwing or soldering some pipes together.) Have you spoken to Burnham yourself, or are the contractors doing that for you? If you yourself haven't spoken to them, I'd give that a try as the next step.
It's actually fairly common for a leak that appears on a cold boiler, to vanish when the boiler is on-line. (Please note that I am NOT suggesting that it is normal for any boiler to leak.) The expansion from cold to hot closes the leak, or it's hot enough that the water evaporates.
