Primary damper
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.
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.
3.1.3 Secondary damper at side glass (do not apply to the Aduro 1.1 series, 9.1 & 9.6)
The stove is equipped with an air-wash system by the side glasses, which can be regulated individually. The
air-wash on the side glasses can be opened and closed by moving the dampers from side to side. You can
use the Aduro key for this purpose.
