Vent A Hood Height
Can anyone offer advice on this situation?
Vent a Hood recommends installing their piece 24-27" from the range top. The range recommends the hood be 30-36". I called Vent a Hood and they said you lose 10% efficiency for every inch you go over. Retailer says their customers always put them at 24-27". The Gas company will not accept 27 inches and they'll end up forcing me to change it.
What to do? Look for another hood is an option I guess. Will I really lose that much efficiency at 30"? Any Vent a Hood users out there?
