3.8 Aduro-tronic
The patent-applied Aduro-tronic is designed to operate the stove for you. All you have to
do is put dry wood in the stove, and activate the control system - Aduro-tronic does the
rest, leaving you to enjoy the flames and the benefits of efficient combustion. Aduro-
tronic is a patent-applied mechanical solution, which works without the use of electricity.
Please note: Use of dry wood of the right size is important to achieve optimum
combustion.
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 optimum moisture content of 17-18%. 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
