3.1.1 Primary damper
When you add new logs, the primary damper should be opened until the fire is burning properly. In order to
utilise the fuel to the fullest extent, the embers should have burnt for so long that it is necessary to open the
primary damper for approx. 2 minutes to get the logs burning. However, it is important to fire at a certain time
so that the flames do not go out during the closing time for the Aduro-tronic.
In order to reduce the risk of ash falling from the stove when the door is opened to add more fuel, it is a good
idea to open the primary damper for approx. 1 minute before the door is opened. This increases the draft
through the stove.
3.1.2 Secondary damper
The secondary damper behind the door allows you to adjust the wood burning stove to the chimney draft and
the required heat output. Turning the damper to the left decreases the air supply and turning to the right
increases the air supply. In normal circumstances, the wood burning stove should be working with this
damper open between 60 % and 100 %. You should never close the air supply so far that the flames go out.
There should always be visible flames in order to achieve a clean and efficient combustion. A too low supply
of air can lead to bad combustion, high emissions, and a low efficiency. The air-wash system that minimises
soot on the front glass is also adjusted by this damper.
If you want to fire in the stove with the lowest possible effect – around 3 kW – you must close the secondary
damper almost completely approx. 45 minutes after stoking. At this point there are only few flames, and the
stove can burn clean by using the tertiary air from the back of the combustion chamber.
3.2 Ventilation / fresh air supply
In order for the wood burning stove to function at optimum efficiency, air is needed for the combustion
process. There must be sufficient fresh air coming into the room where the wood burning stove is placed. In
very well-insulated houses or houses with powerful cooker hoods and/or air conditioning systems, a vacuum
can be created around the wood burning stove, leading to smoke leakage and poor combustion. In these
circumstances, it might be necessary to open a window to provide air for the combustion and to equalize the
vacuum. Alternatively, you could place an air vent in the room where the wood burning stove is placed. The
amount of air needed for the combustion is 25 m
3.3 How should I use my wood burning stove?
The wood burning stove is intended for intermittent combustion. This means that each stoking should burn
down to embers before new logs are added. Always respect the MAX-load line which marks the limit for the
amount of wood.
You can regulate the effect/heat output with the fuel. Burning small logs provides more powerful combustion
than burning large logs. The ideal heat output is reached by burning approx. 1.3 kg wood per hour.
If you experience problems lighting the fire or the fire dies after a short time, it can be due to the following
reasons:
•
The firewood is not dry enough. The firewood should have a moisture content of max. 18%.
•
There is a negative pressure in the house. See section 3.2.
•
The smoke outlet from the outside may be blocked from sooth. This can occur after chimney
sweeping. Control the smoke outlet.
•
The used amount of wood may have been too small. This results in a too little and too cold layer of
embers which cannot light the new wood.
