How high is your range hood?
Our chimney style range hood (Cavaliere, 900 CFM, don't have actual model # right now) installation instructions recommends it be installed no less than 28 inches above the cooktop and no more than 31 inches for maximum performance. When we mocked it up even 31 inches seems really low to me. When I look at pics of other kitchens, the hood always looks more than 31 inches above the cooking surface. Is it just my perception? What height above your cooktop is your hood?
