Hi —
We are trying to vent a 30″ gas grill located on a semi-open porch in a condo. The existing ductwork consists of a straight run of about 8′ of 6″ x 8″ galvanized duct tied into a large copper roof jack. We currently have a 50″ wide hood installed with an internal 1200 cfm fan. The system is simply not removing enough of the smoke from the grill. The original vent hood and grill worked quite well together, but were replaced mostly for asthetic reasons. What’s wrong?

Is there an obstruction in the hood, duct, or vent cap? Maybe the hood is too far from the grill.
