Chimney Sweeping & Creosote Removal (twice a month)
Creosote – Formation and Need for Removal – When wood is burned slowly, it produces tar and other organic va-
pors, 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 connector and chimney should be inspected at least twice
monthly during the heating season to determine if a creosote buildup has occurred. If creosote has accumulated it
should be removed to reduce the risk of a chimney fire.
Since the CleanFire has a fire chamber that is surrounded by air, the metal surface of the chamber is allowed to
heat up with the fire and will prevent creosote from building up during normal opertaion with seasoned wood.
Due to the use of a catalytic converter, the smoke in the exhaust that would potentially create creosote buildup in
the chimney is greatly reduced. However the chimney should be inspected twice a month and cleaned if needed.
Maintenance
To check the chimney, turn the boiler off and remove
the hose clamps that hold the flexible chimney coupling
to the top of the tube access box. Remove any creosote
buildup to reduce the risk of a chimney fire. Inspect the
upper seal for damage. Replace if necessary as described
later in this section.
