The first few times the wood burning stove is used, there may be some smoke and unpleasant odours from the
wood burning stove, which is fairly normal. This is caused by the heat-resistant paint hardening. Make sure there is
sufficient ventilation during this stage. It is also important not to let the fire burn too fiercely the first 2–3 times, so
that the wood burning stove has time to expand slowly. You should also be aware that the stove may make clicking
sounds as it heats up and cools down – rather like pouring boiling water into a sink. These are caused by the great
differences in temperature to which the materials are being exposed.
During the first firing, which should be carried out using approximately 1 kg of wood, the stoking door must be left
slightly open and must not be closed until the stove is cold. This is to prevent the sealing rope sticking to the stove.
4.5 How should I use my wood burning stove?
The wood burning stove is intended for intermittent combustion. This means that each stoking should burn down to
embers before new logs are added.
In order to obtain the best possible combustion, you should regulate the effect/heat output with the fuel. Burning
small logs provides more powerful combustion than burning large logs as the surface area is greater and more gas
is released. The amount of wood in the combustion chamber is another factor that affects combustion. In normal
circumstances, you should not place more than two logs in the stove. If you want an enhanced effect, you can add
more logs. The nominal heat output is reached by burning approx. 1,3 kg per hour.
4.6 Secondary damper
The secondary damper 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. 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. The air-wash system, that minimizes soot collecting on the glass panes, is also adjusted
by this damper.
If you wish 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.
4.7 Primary damper
When you add a new log, the primary air intake/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 air intake for approx. 2 minutes to get the new log to burn.
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 air intake/damper for approx. 1 minute before the door is opened. This increases the draught
through the stove and reduces the risk that ash will drop on the floor.
Please note: if you overload the wood burning stove and burn more than approx. 2.5 kg wood/hour, there is a risk
that the lacquered surface of the stove will become discoloured and eventually fall off. The stove can be resurfaced,
but this is not covered by the manufacturer's guarantee. In the same way, any other damage to the stove caused by
overloading will not be covered by the guarantee.
4.8 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 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
3
containing the wood burning stove. The amount of air needed for combustion is 25 m /h.
