Chimneys are naturally built to last a long time, but that does not mean they don’t require care now and then. Failing to provide due maintenance for a chimney can be the cause of various problems in your home such as accidental fires due to damaged brickwork or health issues because of a defective flue. The liner is one part of a chimney that can lead to various structural problems down the line if it is not given the attention it deserves. Understanding the role that a flue liner plays in the system is vital so you can grasp the need for repairs when something is not right.
The primary function of a flue liner is to allow the system to safely expel flue gases that are produced when combustion of various fuels takes place. Proper sizing of a flue liner is essential in generating sufficient draft in and out of a room.
