What is the required clearance for baffling around heat sources?

The required clearance for baffling around heat sources is 3 inches. This clearance is essential for ensuring safety and proper functioning of heating equipment. Baffling, which is used to redirect airflow, must maintain a safe distance from heat sources to prevent any potential fire hazards or overheating of surrounding materials.

The 3-inch clearance allows for adequate ventilation, prevents excessive heat buildup, and ensures that any heat emitted can dissipate effectively without causing damage or posing a risk of ignition to nearby combustible materials. Following this guideline is crucial for maintaining the integrity of the system and promoting safe operation in residential and commercial settings.
