I don;t even know which end is the intake and which is the exhaust end LOL (Shows how ignorant I am, but I am learning) Looks like there are some more pictures down lower (12 total). One shows the bottom of the unit and I can see a two flange and the other end is a three flange. If I am looking at the right part.

Thanks again
Gary
