connecting to the chimney - provides your home with 1 kW of extra warmth. The curved shape ensures
minimum soot build-up in the pipe and thereby lessens the risk of chimney fires. We only recommend this
solution provided that your brick chimney is completely sealed and has a sufficient draft. You can read
more on the chimney in the next section.
Some Things Worth Knowing about the Chimney
Description of the chimney’s function
The chimney serves as the wood-burning stove’s ‘motor’, and it is crucial to the stove’s proper functioning.
The chimney draft creates a vacuum inside the wood-burning stove. This vacuum serves two purposes:
1.
To remove smoke from inside the wood-burning stove.
2.
To suck air in through the air damper during lighting and combustion, and to keep the glass pane
free of soot.
How to create the best possible chimney draft
Even a quality chimney can function poorly if used improperly. It is crucial that both your wood-burning
stove and the chimney are installed in accordance with the directions; otherwise it will not be possible to
attain satisfactory combustion.
Chimney draft is created by the difference in temperature between the inside and outside of the chimney.
The higher the temperature inside the chimney, the better the chimney draft. It is therefore very important
that the chimney is thoroughly heated before you close the primary damper and limit combustion inside
the stove; see the section on lighting and firing your WIKING wood-burning stove on page 26. Please be
aware that it takes longer to heat a brick chimney than a steel chimney.
On days when weather and wind conditions create a poor draft in the chimney, it is especially important
to heat up the chimney as quickly as possible. When lighting, use extra-finely split firewood and an extra
firelighter, as flames quickly heat up the stove.

After a longer period of disuse
If you have not used your wood-burning stove in a while (e.g. for an entire summer season), it is important
to check for blockage in the chimney duct. Contact your local chimney sweep
