That's a good question Todd. I've always assumed rated flow even though many, as you mention, do show the max flow. I didn't read this nor was I told to do it that way, I just always have. This will be good info when we get the answer.

Is the Rated Flow the maximum? Can it be taken out to a UL Tested flow (which some manufacturer's include in their graph)? I tried to look it up but didn't find anything. Todd G.
