The chimney liner should be inspected by a certified chimney sweep or qualified chimney inspector prior to each heating season. When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. As a result, creosote residue accumulates on the chimney liner. When ignited, this creosote makes an extremely hot fire. If you are burning solid fuel, the chimney liner system needs to be inspected at least once every two months during the heating season, to determine if a creosote or soot buildup has occurred. If creosote or soot has accumulated,it should be removed to reduce the risk of a chimney fire.To remove creosote and soot, use a wire or poly chimney brush. The size of the brush should be the same diameter size as the liner or up to 1/8” larger. Thoroughly brush the liner to remove any buildup that may have occurred. To access the liner, remove the top portion of the cap by removing the screws on the legs.
Be sure to reattach the cap after cleaning liner
