A chimney fire is not an everyday occurrence. (In fact, the less frequent the better!) It’s an accident that burns up the inside walls of the chimney. The flue – which is the passageway within your chimney – may be described as a round container that receives heat from a fireplace (or stove) and has an inlet and an outlet. If enough combustible material accumulates in the flue, you have an ideal scenario for high temperatures and out-of-control burning!
Chimney fires start when months of regular using a fuel-burning fireplace or stove results in build-up along the inside walls of the flue. The substance, known as creosote, may be soft, dry soot or tar-like or even glazed. Some kinds of creosote will catch fire more easily than others, but all kinds are unable to cause a chimney fire once a sweep has cleaned them out. Creosote may be eliminated with chimney sweep brushes or remover chemicals. Listen to your Certified Chimney Professional and decide on the best path of resolution for the creosote in your chimney.
A chimney fire burns the creosote trapped along the inside walls of the flue and may compromise the integrity of the venting system and passageway. You can reduce the risk by having your chimney inspected and cleaned annually!
