Answer: (B)

The necessary clearance from the sides of suspended unit heaters is specified at 18 inches. This requirement is crucial for ensuring safe operation and maintenance access. Adequate clearance helps to prevent overheating, which can occur if the heaters are too close to combustible materials or surfaces. It also allows for proper airflow around the unit, which is essential for efficient heating and to maintain the longevity of the equipment. Furthermore, the specified clearance enables service personnel to access the heater for inspections, repairs, or maintenance without obstructions, enhancing both safety and operational efficiency. Understanding these clearance requirements is vital for compliance with safety regulations and to ensure that the heating system functions correctly and safely in a variety of environments.
