Why would fresh air need to be drawn in? The gas and air is mixing at the opening in the inlet.
As far as fumes and exhaust go that is coming out the top and has nothing to do with air being drawn into the bottom...
Am I missing something?
EDIT: as I look at it again I can see how the exhaust might get trapped in the shroud but the fumes would only be carbon monoxide and some hydrocarbons. Correct me if I'm wrong but this wouldnt make the thing go "boom."
