The minimum clearance to combustible material for unlisted suspended-type unit heaters is 18 inches. This requirement is in place to ensure safety and reduce the risk of fire hazards in environments where such heaters are used. The specified distance helps prevent overheating of surrounding materials, which could ignite if they are too close to the unit heater.

The established clearance serves to allow proper airflow around the heater, which is crucial for its efficiency and safe operation. Unit heaters generate significant amounts of heat, and maintaining this minimum distance is essential for both the effective functioning of the unit and for minimizing the risk of heat-related incidents.

In particular, regulations dictate that this 18-inch clearance is necessary for unlisted units, which may not have undergone the same level of testing or certification as listed units for safe operation. This precautionary measure ensures that, even without certification, the units operate within a safe distance from combustible materials.
