What’s the minimum clearance needed around ductwork in ABC installations?

The minimum clearance of 3 inches around ductwork in ABC installations is intended to ensure proper airflow, prevent heat transfer, and allow for maintenance and inspection. This distance is crucial for preventing heat buildup, which could pose a fire risk or reduce the efficiency of the HVAC system. Maintaining this clearance helps in avoiding the clutter that can obstruct airflow and reduce the performance of the system.

Additionally, having a 3-inch clearance allows for essential structural support and compatibility with insulation requirements. It is also beneficial in terms of accessibility, permitting service technicians to work around the ductwork without the risk of damage or injury. Overall, adhering to this clearance guideline fosters optimal system performance and safety within HVAC design and installation practices.
