6. Place 2 pieces of wood of 0.5-0.7 kg each and approx. 25-30
cm long over the embers in a single layer, with a distance of
approx. 1 cm.
7. Open the air supply to maximum and close the door; the fresh
wood will then ignite within a couple of minutes.
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. Reduce the amount of combustion air to the desired position,
and optimal combustion will continue until there are glowing
embers in the bed.
Make sure that there is always enough air (oxygen) to
maintain clear, lasting flames when, and after, reducing the
amount of combustion air.
During the nominal test, the stoking interval was 60-70 mi-
nutes.
9. A new portion of wood can be added by repeating steps
5 & 6.
The stove door should normally be opened gently the first 2-3
cm, then you should wait until the pressure has equalised be-
fore opening the door all the way. This technique will pre-
vent smoke from getting out, particularly when there is a poor
draugt.
Once the wood has burned out, it becomes glowing charcoall.
If a good layer of embers has already formed on top of a suf-
ficient layer of ash, the stove can keep warm for a very long
time.
