What is the minimum thickness required for the smoke chamber walls?

The minimum thickness required for the smoke chamber walls is typically established to ensure structural integrity and proper function in relation to heat resistance and durability. A thickness of 8 inches is generally sufficient for smoke chambers, allowing them to withstand the temperatures and conditions created during combustion processes within a fireplace or chimney system. This thickness helps prevent cracking and deterioration over time, ensuring safe operation and compliance with building codes. Therefore, choosing 8 inches reflects a standard that balances safety, efficiency, and longevity in construction practices related to smoke chambers.
