What is the minimum height for noncombustible above a range or cooktop without manufacturer's instructions?

The minimum height for noncombustible materials above a range or cooktop, in the absence of specific manufacturer's instructions, is established at 24 inches. This height is critical for ensuring safety and compliance with fire and building codes. It creates a sufficient gap to prevent heat transfer to combustible materials, thereby minimizing the risk of fire hazards.

This standard is designed to protect both the structure and occupants by ensuring adequate clearance between cooking appliances and combustible surfaces. By adhering to this minimum height requirement, it helps to promote a safe kitchen environment and reduces the likelihood of any heat-related incidents stemming from cooking activity.
