6.12.1 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.
6.12.2 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, but mainly cleaning of the gas
path, can be facilitated by removing the baffle. See section «6.9 Air
Tubes And Baffle Installation»
To properly clean all the gas path, it is recommended to use the cleaning brush. To make sure you reach
all corners, especially the top and sides of the oven, it is recommended remove the chimney.
N.B. It is possible to remove the chimney after sweeping. The residues will thus all have fallen on top of the
oven. You can also remove the chimney before sweeping and make sure to put a container as airtight as
possible at the end of the chimney (where it has been unscrewed), to collect the residues that will fall
during the sweeping.
