Should a generator air inlet be facing the wind?

When ever possible, face the generator air inlet openings away from the wind. The wind can prevent the air intake louver from opening on start up. The air inlet must be capable of moving enough air through the room to provide the correct minimum CFM (cubic feet per minute) cooling for generator as specified by the generator's manufacturer.

How do you vent a generator?
