Liners & Pipes
A chimney flue liner or flue pipe is used to line the inside of a chimney or to vent a insert of stove. The liner or pipe serves several important functions, including protecting the chimney from the heat and corrosive gases produced by the fireplace or wood stove, and providing a smooth surface that allows smoke and other combustion byproducts to easily pass through or to the chimney.
