3.1 Air dampers
The stove is equipped with air dampers for regulation of the primary and secondary air supply. The primary
air is used at the beginning to get the fire going, and the secondary air keeps the fire burning evenly. The
tertiary air ensures that flue gasses are burned and is not adjustable. You must always add secondary and
tertiary air, while firing the stove.
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.
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 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 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.
Aduro Key: The stove comes with an Aduro-key which provides easier control of the
secondary damper. The key is fitted onto the control handle in order to easily adjust the
airflow from side to side. See illustration.
3.2 Aduro-tronic
Aduro 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

3.2.1 How to operate Aduro-tronic
When lighting
When lighting a fire in the stove, the maximum amount of primary air will be needed to
light the fire. For that reason, the primary damper can be kept "forcibly open". This is
done by pulling the primary damper out as far as possible and then fixing it with the
Aduro Key (see illustration). When the stove is warm, and a layer of embers has been
created on the bottom of the combustion chamber, the Aduro-tronic can be set to the
automatic position, i.e. the Aduro key can be removed. Alternatively, you can leave the
door ajar the first few minutes during the ignition phase (without the key).
