Fantech fan

in Gas Heating
Had a contractor call me today and asked how much combustion air a Fantech fan would provide. It is connected to an 8" flue piping leading to the outdoors.
I have not gotten the total BTU load of the boiler room but I believe it will be high (2-boilers and 2-water heaters).
I have attach a picture of the fan label.
Any help would be great. Thanks.

Thanks for the reply. I found that information after my post. Contractor gave the total BTU load today, 1,100,000.
If I am correct, by code I need 0.35CFM per minute for per 1,000 BTU input of appliances for a mechanical draft. I math I came up with was 385 CFM needed. 1,100,000 divided by 1,000 = 1,100 X 0.35= 385. I think I'm on the right path. I am just not sure about the 8" duct pipe (flue).
