What is the minimum service clearance vertical requirement for a Boiler?

The minimum service clearance vertical requirement for a boiler is 24 inches. This regulation is in place to ensure safe access for maintenance and operation of the boiler. Adequate clearance helps to prevent overheating of nearby structures and allows technicians to perform necessary inspections and repairs without obstruction. Furthermore, the clearance is important for ventilation purposes, helping to maintain appropriate air flow around the boiler, which is crucial for proper combustion and efficiency. Proper adherence to these clearance requirements is essential for the safe and effective operation of heating systems.
