finished a install with a monessen direct vent and noticed some discrepancies in the owner/ install manual or maybe its me... the manual states rough opening of "41.75 inches height" and "do not use flanges for framing or header" , "for drywall support only" BUT my header is at the flange? any input or suggestions appreciated? i really don't want to start cutting up the framing...
