In some cases a permit will be required. To be certain, contact your building inspection department or fire department. Chimneys Each piece of wood-burning equipment will require a chimney or flue suitable for use with solid fuels. Metal flues used to vent your gas furnace are not suitable for your wood burner. Whether masonry or metal, the chimney should be properly constructed.
Manufacturers usually specify flue dimensions and chimney requirements for their products.
This means that a chimney of this design has passed a safety test. If you install the chimney yourself, adhere strictly to the manufacturer's instructions. Chimneys should extend at least 2 feet above the roof ridge or 2 feet above any point of the roof within 10 feet of the chimney. On flat roofs be sure that the chimney extends at least 3 feet above roof level. If a factory built chimney extends more than 4 feet above the roof, additional support should be provided.
