«Creosote - Formation and Need to 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 cooler
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 once every two months
during the heating season to determine if a creosote buildup has occurred.
If a significant layer of creosote has accumulated (⅛» [3 mm] or more) it should be removed
to reduce the risk of a chimney fire.»

Frequency

It is not possible to predict how much or how quickly creosote will form in the chimney. It is
important, therefore, to check the build-up in the chimney monthly until the rate of creosote
formation is determined. Even if creosote forms slowly in the system, the chimney should be
cleaned and inspected at least once each year.
Establish a routine for the fuel, wood burner and firing technique. Check daily for creosote
build-up until experience shows how often you need to clean to be safe. Be aware
that the hotter the fire the less creosote is deposited, and weekly cleaning may be necessary in
mild weather even though monthly cleaning may be enough in the coldest months. 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.
6.5.1 Sweeping the Chimney
Chimney sweeping can be a difficult and dangerous job. People
with no chimney sweeping experience will often prefer to hire
a professional chimney sweep to inspect and clean the system
for the first time. After seeing the cleaning process, some will
choose to do it themselves.
The chimney should be checked regularly for creosote build-up.
Inspection and cleaning of the chimney can be facilitated by
removing the baffle. See
Installation»for more details.
6.5.2 Chimney Fire
Regular chimney maintenance and inspection can prevent chimney fires. If you have a chimney
fire, follow these steps:
1. Close the stove door and the air intake control;
2. Alert the occupants of the house of the possible danger;
3. If you require assistance, alert the fire department;
4. If possible, use a dry chemical fire extinguisher, baking soda or sand to control the fire. Do not
use water as it may cause a dangerous steam explosion;
Do not use the appliance again until the stove and its chimney have been inspected by
a qualified chimney sweep or a fire department inspector.
