Creosote-Formation and Need for Removal-When wood is burned
slowly, it produces tar and other organic vapors, which combine with
expelled moisture to form creosote. The creosote vapors condense in
the relatively cool chimney flue of a slow-burning fire. As a result,
creosote residue accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire. The chimney and chimney
connector should be inspected at least twice monthly during the
heating season to determine if a creosote build-up has occurred. If
creosote has accumulated it should be removed to reduce the risk of a
chimney fire.
