What are the minimum clearance requirements for installing this range under cabinets?

A minimum of 30" clearance is required between the top of the cooking surface and the bottom of an unprotected wood or metal cabinet. This can be reduced to 24" if the cabinet bottom is protected by at least 1/4" flame-retardant millboard covered with appropriate sheet metal. A minimum of 15" is required between the countertop and adjacent cabinet bottom. (Page 2)
