Annual inspections keep flames burning right
Creosote—combustible, tar-like droplets—is a natural byproduct of burning wood. The more wood you burn, the wetter or greener the wood, and the more often you restrict airflow by keeping your fireplace doors closed or your damper barely open, the more creosote is produced.
Soot build-up, while not flammable, can hamper venting. One half-inch of soot can restrict airflow 17% in a masonry chimney and 30% in a factory-built unit, according to the CSIA. Soot is also aggressively acidic and can damage the inside of your chimney.
The more creosote and soot, the more likely you are to see signs of chimney fire—loud popping, dense smoke, or even flames shooting out the top of your chimney into the sky. Chimney fires damage the structure of your chimney and can provide a route for the fire to jump to the frame of your house.
“If the chimney is properly maintained, you’ll never have a chimney fire,” says Ashley Eldridge, the education director of the CSIA.
