Zippi,

Thanks! I was just making sure I was on the same page. I've never used the term baffling, just ducting and venting. A baffle to me would be a deflector of some sort in a vent pipe or duct.

Been around awhile myself, but hate to reinvent the wheel if I don't have to so I ask questions and go from there as you suggested!

Good flying and thanks again gents.
