What is the minimum clearance required for a medium-heat commercial oil stove from combustibles when connected to a masonry chimney?

The minimum clearance required for a medium-heat commercial oil stove from combustibles when connected to a masonry chimney is indeed 36 inches. This clearance distance is critically important for fire safety and to prevent any potential ignition of surrounding materials due to heat generated by the stove. Oil stoves can produce substantial heat, and maintaining this distance ensures that the heat is dissipated adequately, reducing the risk of overheating any nearby combustibles.

Additionally, this regulation aligns with industry standards and local building codes that aim to ensure safe installation practices. The specified distance serves to create a buffer zone where heat and flames are less likely to interact with flammable materials, safeguarding both property and lives.
