Burning varnished wood, impregnated wood, chipboard, paper, and other waste is strictly forbidden. Burning
these materials will damage the environment, the wood burning stove, and your own health. Fossil fuels
must not be used.
The stove is tested in accordance with current standards, where a smoke exhauster secures a constant
chimney draft of 10-14 Pascal (Pa). However, with a natural draft (without a smoke exhauster installed) the
chimney draft will increase to 18-25 Pa at optimum conditions. There are many factors that affect the
chimney draft, including the outside temperature, wind strength, and surrounding buildings. There are no
requirements with respect to specific chimney heights, but a chimney must be tall enough to provide a good
draft. If the recommended chimney draft is not achieved, there may occur problems with smoke coming out
of the door during firing.

4.1 Inadequate draft in the chimney
If you experience poor draft in the stove after the installation, please make sure that there is nothing in the
chimney to restrict the smoke and that no nearby buildings or trees affect the winds around the chimney.
If the chimney is too short, leaks, or is inadequately insulated, there may be problems with the chimney draft
(let the chimney sweep assess this). The draft should be sufficient during the ignition phase when the
stove/chimney is cold to provide a clean combustion and prevent smoke leakage. Therefore, we recommend
a chimney draft around 5 Pa in the ignition phase.
Once the ignition is a success, and the smoke temperature is rising, it is important that the chimney draft
reaches a stable area around 18-25 Pa in operation (1 hour after ignition) when the chimney/stove is hot.
The draft in the area of 18-25 Pa when the stove is hot is essential in order to achieve an optimum and clean
combustion. Therefore, we recommend that you measure the chimney draft when the chimney is cold and
when it is hot after 1 hour in operation.
In practice, the chimney draft will differ – especially in cold condition. Therefore, the best indication of the
chimney draft is to measure the draft when it is hot. If the chimney sweep judges the draft to be sufficient, but
you still have problems lighting a fire, try extending the ignition phase by using more thin pieces of kindling
and 1-2 firelighters, so that the chimney gets thoroughly warm. The chimney will not draw at optimum effect
until it is warm. When a layer of embers has been formed, add 2-3 dry logs.
If it is impossible to establish a sufficient natural chimney draft, you can mount a smoke exhauster, e.g.
Aduro
DraftOptimizer.
4.2 Chimney and smoke
If you experience smoke coming out of the stove or the start section of the smoke pipe, it could be due to
certain weather conditions. On stormy or cold winter days, or if the chimney has not been used in a while, a
cold plug can be created in the chimney, meaning the natural draft will be at its minimum.
