The fireplace flue
The fireplace flue services wood stoves, pellet stoves and any other solid fuel appliance. It may have undergone a chimney fire or has been connected to an improperly vented appliance. If a wood stove is attached it may be misused or exposed to excessive moisture. A damaged flue brings the dangers of fire and carbon monoxide poisoning. Some signs to look for of a deteriorating fireplace flue are: Cracked or missing tiles.Eroded brick and mortar.Excessive or glazed creosote.The joints of the flue tiles are not sealed.The flue tiles are not aligned properly.Improper chimney draft.If your fireplace flue vents an open fireplace and any of the above signs are visible, a stainless steel reline is your best option to stop the deterioration of your chimney and/or flue. To reline an open fireplace, the total liner length will be the distance from the top of the smoke chamber to the top portion of the chimney. Fireplace Liner Guidelines The liner assembly will be supported from the top of the chimney by use of a top plate with built in clamp systems. A bottom plate is also used. This bottom plate has a 2" collar which will connect to the bottom of the stainless steel liner. Support rods or bottom plate leg supports can be used but are not necessary. Before relining your fireplace flue the installer must first verify that there is at least 1" of clearance to combustibles and that outside there is a 3" nominal layer of masonry to insure safe operation of the fireplace.
