3.8.1 How to operate Aduro-tronic
When lighting
When lighting a fire in the wood burning stove for the first time, 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 forward 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 minutes during lighting
the fire (without the key).
When stoking
Each time fresh wood is put in the stove, a precise amount of primary air
will be allowed in for the first few minutes. What's more important is that
the primary air is not allowed in for too long. This is to ensure optimum
combustion. The Aduro-tronic control will ensure intake of primary air at
the right tempo. The automatic is activated by pulling the primary damper
out each time fresh wood is put in the stove. The automatic closes then
the primary air gradually.
Regulation of the Aduro-tronic control
The control is pre-set to allow primary air intake for the first 5 minutes.
This setting has been used during testing at the Danish Technological Institute using 'standard' sized logs and with
maximum moisture content of 18%. Standard size logs are approx. 30 cm long and 10 x 10 cm in thickness. A
standard chimney was also used for testing. In practice, such circumstances can differ, which is why the Aduro-
tronic control can be adjusted to your circumstances. If you want a slower intake of primary air: (e.g. for a slower
flue draught, larger sized wood or for longer intervals between stoking) Adjust the screw on the front of the control
level using a small allen key to slow closure rate. If the screw is turned to the right closing time is increased and if
turned to the left closing time is reduced. The Aduro-tronic must be closed within 6 minutes.
3.9 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 containing the wood burning stove. 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 combustion and to equalize the vacuum. Alternatively, you could fit
an air vent in the room containing the wood burning stove. The amount of air needed for combustion is 25 m
4.0 The chimney
Data for chimney calculation:
Flue temperature at [20 C]
Chimney draught at testing power
[mbar]/[Pa]
Flue gas mass flow [g/s]
The optimum combustion is achieved at a constant chimney draught of 0.10 to 0.14 mbar measured in the flue pipe
above the stove. There are many factors that affect the chimney draught, including the outside temperature, wind
strength and surrounding buildings. If it is impossible to establish a sufficiently natural chimney draught, the
chimney can be fitted with a smoke extractor. If the chimney draught is too strong, a damper can be fitted to
regulate the chimney draught. Contact your local chimney sweep for more advice.
There are no requirements with respect to specific chimney heights, but a chimney must be tall enough to provide a
good draught – above 12 Pa. If the recommended chimney draught is not achieved, there may be problems with
smoke out of the door by firing.
