What is the required vertical clearance above cooking appliances to combustible materials?

The required vertical clearance above cooking appliances to combustible materials is 30 inches. This requirement is in place to ensure safety by preventing any potential fire hazards. Cooking appliances generate significant heat, and without adequate clearance, there is a risk of igniting nearby combustible materials such as cabinets, walls, or other surfaces. The 30-inch standard is established by various safety codes and regulations to provide a buffer zone that significantly reduces the risk of fire.

This distance is also important for maintaining proper airflow, which can help to keep the cooking area safe and functional. Proper installation practices adhere to these clearance requirements to ensure that the cooking environment is safe for both the appliance operation and the surrounding structure.
