Creosote

Formation and Need for Removal

When wood is burned slowly, it produces tar and other organic vapours, which combine with

expelled moisture to form creosote. The creosote vapours condense in the relatively cool

chimney fl ue of a slow burning fi re. As a result, creosote residue accumulates on the fl ue

lining. When ignited, this creosote makes an extremely hot fi re.

The chimney connector and chimney should be inspected periodically (at least once every

two months) during the heating season to determine if a creosote buildup has occurred. If

creosote has accumulated (3 mm. or more), it should be removed to reduce the risk of a

chimney fi re.

Highest smoke densities occur when a large amount of wood is added to a bed of hot

coals and the air inlet is closed. The heated wood generates smoke, but without ample

air, the smoke cannot burn. Smoke-free, clean burning requires small fuel loads, two

or three logs at a time or 1/4 to 1/2 of fuel load and leaving the air inlet relatively wide

open, especially during the fi rst 10 to 30 minutes after each loading, when most of the

smoke generating reactions are occurring. After 30 minutes or so, the air inlet can be

turned down substantially without excessive smoke generation. Wood coals create very

little creosote-producing smoke.

2. The cooler the surface over which the wood smoke is passing, the more creosote will

be condensed. Wet or green wood contributes signifi cantly to creosote formation as the

excess moisture that is boiled off cools the fi re, making it difficult for the tars and gases

to ignite, thus creating dense smoke and poor combustion. This moisture-laden smoke

cools the chimney, compounding the problem by offering the smoke the ideal place to

condense.

In summary, a certain amount of creosote is inevitable and must be lived with. Regular

inspection and cleaning is the solution. The use of dry, seasoned wood and ample

combustion air will help to minimize the buildup.

Chimney Fires

Excessive creosote build-up can cause a chimney fi re. Creosote comes from tar and organic

vapours released from a slow burning wood fi re. Flammable creosote will condense and

accumulate in the lining of a relatively cool chimney. When ignited, this creosote can result

in an extremely hot fi re.

Avoiding a Chimney Fire

There are two ways to avoid chimney fi res:

Keep your chimney clear of creosote build-up by cleaning your chimney before each

burn season, and as necessary (accumulations of 3 mm/1/8" or more) during the

season.

2. Burn clean, well-seasoned wood only (seasoned at least one year). Avoid wet or

green wood.

3. Do not burn household trash, cardboard, plastics, construction lumber, treated or

beach wood (as these will corrode your fi replace and void your

warranty).

4. Do not leave the air inlet wide-open for extended periods of time.

5. Keep a fi re extinguisher handy.

6. Prepare a home evacuation plan with a place outside where everyone

is to meet.
