2.1 lighting instructions and fuelling intervals

A lot of air is needed when lighting the stove. If you are starting with a cold stove, the door
should be left ajar for the first few minutes. In order to build up an insulating layer of ash in
the bottom of the stove, you should burn 3 kg of dry kindling when you light the stove the
first time.
Always keep approx. 1 cm ash in the bottom of the combustion chamber.
1. A layer of embers will form rapidly if the stove is lit with 2-4 fuel tablets or 7-10 rolled-up
sheets of newspaper underneath approx. 3-4 kg dry kindling.
2. Open up completely for the secondary air supply by means of the regulation lever.
3. After the paper/solid alcohol tablets have caught fire, leave the fire door ajar about 2 cm
so that the chimney draws well.
4. When you can see that the chimney is hot enough to draw (after 5-10 minutes), close the
door. If all the necessary conditions are met, a thick layer of embers will have been formed
in the combustion chamber after another 15-20 minutes.
5. Re-stoking should normally be carried out while embers still remain. Distribute the em-
bers in the bottom, ensuring that most of them are at the front of the stove.
6. Place 2-4 logs of firewood, each weighing approximately 0.7-1 kg and 30-60 cm long, over
the embers in one layer separated by approximately 1 cm. The best combustion is obtained if
the longitudinal dimension of the logs is parallel with the rear wall of the stove.
7. When the secondary air supply is opened to maximum and the door is closed, the new
quantity of wood will ignite in a few minutes.
Important!
It is important that the fresh quantity of wood starts to burn quickly. To ensure the
fuel lights quickly, open the combustion air to max. or leave the door ajar to allow in the
amount of air needed to light the wood.
If, however, the wood only smoulders, there will be a strong build-up of smoke, which
at worst can cause an explosive ignition of the flue gases with the risk of material
damage and personal injury.
8. Subsequently, the secondary air supply is adjusted to the desired level, and the optimum
combustion will continue until only embers are left.
Make sure that there is always enough air (oxygen) to maintain clear, lasting flames when,
and after, reducing the amount of combustion air.
Under the nominal test, the refill interval was 60-70 minutes.
9. A new portion of wood can be added by repeating steps 5 & 6.
