What is the minimum distance between a chimney's clearance and combustibles in an attic space?

The minimum distance required between a chimney's clearance and combustibles in an attic space is 2 inches. This requirement is established to ensure safety and prevent any potential fire hazards that can arise from heat generated by the chimney. The clearance distance allows for proper airflow around the chimney, which helps to dissipate heat and reduce the risk of igniting nearby combustible materials such as wood framing, insulation, or other structural components often found in attics. Ensuring this clearance is not only a matter of safety but also a compliance requirement with building codes and standards for residential construction.
