True or False: Chimneys for factory-built fireplaces require specific clearances and support components.

The statement is true because chimneys for factory-built fireplaces are designed with specific requirements to ensure safety and functionality. These requirements include maintaining certain clearances from combustible materials to prevent fire hazards. Additionally, factory-built chimneys often must be supported by specific components that are designed to handle the weight and thermal expansion of the chimney system. Adhering to these clearances and support requirements is critical to ensure the chimney operates correctly and complies with safety standards. Proper installation according to manufacturer guidelines and local codes is essential to prevent potential hazards associated with improper chimney use.
