re: Anyone have a vent over their grill/smoker?

1200 cfm is quite a draw of air. Even with a breeze, it will direct the air upward. now, if it's gusting, you're gonna get some blow-by. but in fairly light breezes, most of the smoke will go up. Esp if you have a 4' long exhaust hood or two 48" side by side.

Another thing to consider is cleaning that bad boy. If you move the grill to a non-vent location, you've eliminated a big old spot of maintenance/cleaning. The baffle-style & grease drip rail exhaust hoods have lots of surface area that can & will attract dirt, mud daubers, etc. I've reached the point in my life where I don't need another shiny thing to clean. I just want functional and easy care.
