When installing a wood oven, it is crucial to adhere to proper set-back distances from combustible materials to ensure safety and prevent the risk of fire. The specific set-back requirements can vary depending on local building codes and regulations, as well as the manufacturer’s recommendations. However, as a general guideline, it is common to maintain a minimum distance of at least 36 inches (or 91 centimeters) from combustible materials such as walls, structures, or other flammable surfaces. This distance allows for proper air circulation and reduces the risk of heat transfer to nearby materials. It is important to consult local building authorities or a professional installer to ensure compliance with the specific set-back requirements in your area.
