A typical chimney is required to be a minimum of how many feet high?

A typical chimney is required to be a minimum of 3 feet high to ensure proper venting of combustion gases and to reduce the risk of backdrafting. This height helps create an adequate draft necessary to facilitate the effective expulsion of smoke and odors from the home. Additionally, the chimney must extend above the roofline to prevent the accumulation of debris and to protect against potential wind effects that could disrupt the chimney's function. Proper chimney height is crucial for maintaining safe and efficient operation of heating appliances.
