The illustration below shows the stove seen from the front with the dampers indicated. Use the edge of the
door to read the position of the air supply.
4.1.1.1 Primary air
When you add a new log, the primary damper should be opened until the fire is burning properly. In order to
utilize 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 new log to burn.
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 and reduces the risk that ash will drop on the floor.
4.1.1.2 Secondary air
In normal circumstances, the stove should be working with the secondary air supply open between 60 % and
100 % (the damper is placed between position 2 and 3. See section 3.1). 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.
If you want to fire in the stove with the lowest possible effect
– around 3 kW – you must close the secondary
air 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.
4.1.2 Aduro-tronic
Aduro hybrid stoves are equipped with the patented Aduro-tronic automatic as a standard. Aduro-tronic is a
manually operated mechanical start-up device, which works without the use of electricity. It automatically
regulates the combustion air and thus secures an efficient combustion. For further information, go to
1: Fully open primary, secondary, and tertiary air inlet.
This position can be maintained with the Aduro Key,
which must be placed in the two holes (see section
4.1.2.1).
2: Closed primary air inlet, fully open secondary and
tertiary air inlet.
3: Closed primary air inlet, halfway closed secondary
air inlet, and fully open tertiary air inlet.
4: Closed primary and secondary air inlet, fully open
tertiary air inlet.
5: Regulator pushed all the way in. All air inlet closed
(only used when burning wood pellets).
