Hey everyone. Replacing an old Weil-McLain with a Burnham Series 2 299k BTU (input).There are 6 loops going to 6 apartments (Building size is approximately 5,800 Sq Ft).-It is a baseboard heating systemThe heating contractor has ordered an Amtrol Extrol SX-60V expansion tank (32 gallon tank volume) to use on the system (floor standing). Reading the literature on Amtrol's website (link below), it appears that this model is grossly oversized.However, when I pointed this out to him, he insisted that it's what my system needs. So I turn to you: Is there any way that a 299k boiler would need such a large expansion tank?Here is a link to the Amtrol sizing chart:http://www.amtrol.com/media/documents/extrol/9015183_07_16_EXTROL_IO.pdfAmtrol Extrol Specification details:http://www.amtrol.com/media/SUBMITTAL/p44_Submittal_01_17.pdfAnd if it is too big, will that cause any problems? Is it worth arguing over or should I just let it go?Thank you!

If it were me:I would cancel the order for the bladder expansion tank because you can have him install a steel expansion tank in the ceiling joists of the basement near the new boiler and not have to deal with having an air scoop, bleeding radiators and have a much simpler system to live with...
