ICC-ES AC375
Full Name
ICC-ES AC375 – Acceptance Criteria for Field-constructed Fireplace Systems Using Prefabricated Blocks
Scope
ICC-ES AC375 outlines the acceptance criteria for field-constructed fireplace systems that utilize prefabricated blocks. These fireplaces are typically wood-burning or gas-fired and are constructed on-site using pre-made components.
The scope of AC375 includes:
- Materials: it specifies the requirements for the prefabricated blocks, mortar, chimney components, and other materials used in the fireplace system, ensuring their compatibility, durability, and fire resistance.
- Design and construction: it details the design and construction requirements for the fireplace system, including dimensions, clearances, structural integrity, and venting, to ensure safe and efficient operation.
- Performance: it outlines the testing methods and acceptance criteria for evaluating the performance of the fireplace system, including its ability to withstand high temperatures, resist thermal shock, and contain combustion products.
- Installation: it provides guidelines for the proper installation of the fireplace system, including foundation requirements, chimney connections, and clearances to combustibles, to ensure safe and compliant installation.
The AC375 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their fireplace systems comply with the applicable building codes and standards.
