First of all light at back !should be at front
Second thing the size of air exhaust pipe was missing. Hard to find the size 6 inches to convert into 4 inches to connect existing pipe
Third the size of  stainless steel metal is too less and visible exhaust hose , needed extra piece to cover ceiling
The most important thing this is not same model as described here they sent me similar product model H700 series instead of
ModelS307H-75.  There is no where mention the CFM in booklet.  I am going to return the product
