If you are using the chimney to vent a fireplace, wood, coal or pellet stove or a gas or oil appliance, the flue should be inspected and cleaned, if needed, once a year. You should also have your chimney inspected if you know, or think, you have experienced a chimney fire. The sudden rise in temperatures within the flue associated with a chimney fire is often the main cause of tiles cracking. Because of this it is a good idea to have your chimney inspected after any chimney fire before you use that flue again.
Stainless steel pipe, either rigid or flexible, made for relining flues of masonry chimneys when the original clay liner has cracked or broken. May also be used to create a lining in a masonry chimney that was made without a clay liner.
Protective coverings for chimneys usually made of aluminum, galvanized or stainless steel, or copper. Most chimney caps have a mesh screening that serves the dual purpose of spark arrestor and barrier against animals. Chimney caps also prevent rain from entering the flue of the chimney.
A device installed at the top of a chimney for the purpose of sealing the flue shut when the fireplace is not in use. They are often used as replacements for throat dampers that are installed just above the firebox when a masonry chimney is built. Lyemance and Lock-Top top-sealing dampers are as much as 90% more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.
