I've only installed on hood like this, at my Mother-n-law's. I am the tallest person in the family, so I got it down as close to the range as possible, but with room so I couldn't bump my head.
Standing at the stove, if I bend forward to reach something on the back, I have about 2 inches of clearance between my head and the stove.
Other than that, I'd guess the only requirement would be aesthetics.
