What is the required space between a chimney and wood framing?

The required space between a chimney and wood framing is 2 inches. This separation is necessary to prevent heat transfer from the chimney to combustible materials, reducing the risk of fire. Chimneys operate at high temperatures, especially when transporting exhaust gases from fireplaces, stoves, or furnaces. If proper clearance is not maintained, the heat generated could ignite nearby wood framing or other combustible components, leading to a potential fire hazard. The 2-inch clearance ensures that adequate air circulation can occur around the chimney, helping to dissipate heat and maintain safety standards as defined by building codes and manufacturer specifications.
