If the cabinets are installed above the cooktop, allow a minimum 30″ (76.2 cm) clearance between the cooking surface and the bottom of the cabinet. A non-combustible material must be installed on the under side of the cabinet.

The maximum depth of cabinets above the cooktop is 13″ (33 cm). EXCEPTION: Installation of a listed microwave oven or cooking appliance over the cooktop shall conform to the installation instructions packed with that appliance. Working areas adjacent to the cooktop should have an 18″ (45.7 cm) minimum clearance between the countertop and the bottom of the cabinet. If the clearance is less than 18″ (45.7 cm), the adjacent cabinets should be at least 8″ (20.3 cm) from the side of the cooktop. 21
