Few things can match the cozy charm of a roaring fireplace, but to keep that fire burning safely, your chimney must have a properly functioning chimney liner. Chimney liners enable the heat and assorted chemical gasses that develop in the fireplace to be carried safely up and through the chimney in order to be released outside. Chimeny liners that become damaged must be replaced as soon as possible in order to operate the fireplace efficiently and safely. Chimney liners should be inspected annually as part of your yearly chimney cleaning chore. Without a properly functioning chimney liner, the mortar between the bricks of the chimney can be eaten away. Instead of having dangerous gasses escape through the chimney and into the fresh air, they can retreat back into the house and harm the home’s occupants. When looking to select a chimney liner for a new chimney or to replace a defective liner, there are three main choices. The most common chimney liners are made from clay tiles which allow for the even distribution of heat as wood in the fireplace continues to burn and vent smoke and gasses. Metal chimney liners constructed of stainless steel or aluminum are a good choice for wood burning or gas operated fireplaces. Cast-in-place chimney liners are the third option, permanent liners that are the most lightweight of the three choices but which can still add stability to an aging chimney structure. Ask your chimney professional which category of chimney liners is the best choice for your chimney structure, Heavy, featuring the strongest and thickest liner construction, High Performance Light or Light. Installing a chimney liner should be done by a professional who will also be responsible for its annual maintenance check. Be sure that the chimney liner you purchase features an Underwriters Laboratories (UL) listing for optimum performance in preventing fires as well as a lifetime warranty. When a chimney liner is properly secured in place, the venting performance of the fireplace will actually be improved. Chimney liners that are too small can negatively affect the venting process.
