Important safety information
• The wood burning stove will become warm during use and therefore it should be treated with all
necessary caution.
• Never keep easily combustible fluids such as petrol in the vicinity of the wood burning stove.
• Never use easily combustible fluids to light the fire in the wood burning stove.
• Never empty the ashpan when the wood burning stove is warm. Embers may still be found in the
ashpan for up to 24 hours after the fire has gone out. Please wait to empty the ashpan until you
are sure that there are no embers in the ash.
• The door should be kept closed while the wood burning stove is in use. While lighting the fire, the
door can stand ajar for the first few minutes.
• In the event of a chimney fire: Close all the dampers on the wood burning stove and call the fire-
fighting service.
3.1 Damper
The stove is equipped with different dampers, which regulates the combustion air: primary, secondary, and
tertiary air supply. The primary air is used at the beginning to get the fire going, the secondary air keeps the
fire burning evenly, and the tertiary air ensures that flue gasses are burned. You must always add secondary
and tertiary air, while firing the stove.
3.1.1 Secondary damper
The secondary damper behind the door should always be open while the wood burning stove is in use. This
damper allows you to adjust the wood burning stove to the chimney draft and the heat output you require.
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 intake so far that the flames are extinguished. There should always be
visible flames in order to achieve clean and efficient combustion. A too low supply of air can lead to bad
combustion, high emissions and a bad efficiency. The air-wash system, that minimizes soot collecting on the
front glass pane, is also adjusted by this damper.
If you want to fire the stove with the lowest effect possible – around 3 kW – you must close the secondary
damper almost completely 45 minutes after the wood has been put in. At this point there are only few flames
and the stove can burn clean by using the tertiary air from behind in the stove.
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.
3.1.2 Primary damper
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.
