Chimney and Chimney Connector Maintenance
5.2.1 Why Chimney Cleaning is Necessary
Wood smoke can condense inside the chimney connector and chimney, forming a
combustible deposit called creosote. If creosote is allowed to build up in the venting
system it can ignite when a hot fire is burned in the stove and a very hot fire can progress
to the top of the chimney. Severe chimney fires can damage even the best chimneys.
Smouldering, smoky fires can quickly cause a thick layer of creosote to form. When you
avoid smouldering so the exhaust from the chimney is mostly clear, creosote builds up
more slowly. Your new stove has the right characteristics to help you to burn clean fires
with little or no smoke, resulting in less creosote in the chimney.
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 stove 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.
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.
