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 your 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 fire lighting 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 sufficiently natural chimney draft, the chimney can be fitted with 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.
If the chimney is cold and cold plugs are created, you may experience smoke leaks during the ignition and
startup phase. In this situation there can be more smoke than usually in the combustion chamber and some
of it might leak out of the stove. Therefore, if you have a cold chimney that has not been used for a while, we
recommend that you use some wood sticks to heat the chimney and eliminate the cold plug.
5. Maintenance and cleaning of the stove
Pakninger
Med tiden bliver pakningerne slidte og bør derfor efterses. Er de utætte, bør de skiftes.
Combustion chamber
The fireproof tiles in the combustion chamber eventually wear out and should be replaced when the cracks
are more than 0.5 cm. The durability of the tiles depends on how often and how intensively the stove is used.
You can change the tiles yourself.
They are available as a ready-to-use set. For further information, go to
Glass
Wet wood, unsatisfactory chimney draft, and wrong use of the stove can leave soot stains on the glass pane.
They can easily be removed using a damp cloth that you dip in cold ash and rub on the sooty glass. Special
cleaning agents are also available to remove soot from glass, e.g. the Aduro Easy Clean pad. The pad
All maintenance and cleaning of the stove should be carried out when it is
cold.
