What is the minimum distance from a cook top to an approved microwave?

• A. 24 inches
• B. 12 inches
• C. 30 inches
• D. 18 inches

Answer: (A)

Heat management and safe appliance ventilation are key when a microwave is installed above a gas cooktop. The NFPA 54 requirement sets a minimum vertical separation to keep radiant heat, steam, and cooking splatter from affecting the microwave and its venting, and to protect nearby surfaces from heat exposure. A 24-inch clearance provides enough space for the microwave’s circuitry and insulation to stay within safe temperatures while allowing the exhaust and any grease ducts to operate effectively. If you’re cooking at high heat or with large pans, follow the manufacturer’s installation instructions, which may call for more clearance. Distances smaller than this increase the risk of heat damage or nuisance issues, while larger distances go beyond what’s necessary for standard operation. So the minimum required distance is 24 inches.
