″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 shall be inspected at least twice a year during the heating season to determine when
a creosote buildup has occurred. When creosote has accumulated, it shall be removed to reduce
the risk of a chimney fire.
5.2.2
HOW OFTEN SHOULD YOU CLEAN THE CHIMNEY?
It is not possible to predict how much or how quickly creosote will form in your chimney. It is
important, therefore, to check the build-up in your chimney monthly when getting used to the
new fireplace until you determine the rate of creosote formation. Even if creosote forms slowly in
your system, the chimney should be cleaned and inspected at least once each year. Do not allow
more than 1/8
(3 mm) creosote buildup in the chimney.
It is recommended to clean thoroughly the chimney system at the end of every heating season.
During summer, the air is damper and with minimal air circulation within the stove or furnace, it
can mix with creosote and/or sooth deposits in the chimney system to form an acid that could
accelerate the corrosion process and induce premature decay of the steel. Corrosion damages are
not covered under warranty. Have your chimney system cleaned by a professional chimney sweep.
Use a plastic or steel brush.
Contact your local municipal or provincial fire authority for information on how to handle a
chimney fire. Have a clearly understood plan to handle a chimney fire.
