What is the minimum walkway clearance around a boiler?

The minimum walkway clearance around a boiler is typically 18 inches. This distance is important to ensure safe access for maintenance and operation of the boiler. Adequate clearance allows technicians to perform necessary inspections, repairs, and service work without risking injury or damaging equipment.

Maintaining an 18-inch clearance also helps with proper airflow and ventilation, which is crucial for the efficient operation of the boiler. Insufficient clearance can lead to safety hazards, such as blocked access in emergency situations or inadequate ventilation, which can affect combustion efficiency and lead to potential carbon monoxide buildup.

In HVAC systems, these clearances are often outlined by local codes, manufacturers' specifications, and industry best practices, all aiming to prioritize safety and functionality.
