Sunrad EDR

Bought a house last year that has mostly Sunrad (or sunrad style) radiators. I'm just trying to see how many EDR for the units, but can't find any guidance. Anybody know where I can get it?
Thanks,

The American Standard Catalog
gives those ratings as 2.0 ft.² and 3.0 ft.² EDR, respectively. I wonder why there's a discrepancy?Just another DIYer | King of Prussia, PA

Thanks guys
Reason I ask is because when we moved in, there were two places where radiators had been disconnected and removed. I have no idea why. If I find out that I've got only 275 SF of EDR installed but that my boiler has capacity for 360, I can reinstall those radiators without compromising the system, right?0 -
Heat Loss
Not only will it not adversely affect the system, if you do a heat loss of the areas they've been removed, you will probably discover they're needed.0
