Heat, exhaust length and future service are all likely reasons for not burying the generator exhaust in the back cap on a gasser. Obviously not a choice on the front mounted diesel generators. You will notice that the Genturi only adds a short elbow to the exhaust dynamics, with an open air stack going up from that point. This creates a very effective Venturi action, and also cools the exhaust substantially.
For those wondering if they need an extension, remember that roof mounted ACs and other ventilation are up there. Get the top of the Genturi 18" above the roof.
