The descriptive info on Amazon says "telescopic chimney fits up to 9-ft. ceilings".  The installation booklet says maximum from floor to ceiling is 101".  9 feet is 108"!! The hood is at least seven inches too high off the range top.  How is this not misleading?  I did not expect to need an extension based on the product description.
