The stove door must be opened gently the first 2 - 3 centimetres, then you should wait until
the pressure has equalised before opening the door all the way. This technique will prevent
smoke from getting out, particularly when there is a poor draught.
The stove door should never be opened when the stove is being fired vigorously.
Once the wood has burned out, it becomes glowing charcoal. If a good layer of embers has
already formed on top of a sufficient layer of ash, the stove can keep warm for a very long
time, not least due to the favourable qualities of the cast iron.
We would strongly recommend that you do not leave your stove alit at night. It
harms the environment, and constitutes very poor use of the wood, as the ga-
ses in the wood do not ignite at the low temperature, but settle as soot (unbur-
ned gases) in the chimney and stove. Extreme conditions, such as poor draught
in the chimney, large quantities of wood or wet wood, may, in the worst-case
scenario, cause an explosive ignition.
When firing in the summer period, when there is minimal need for heat, the
combustion will be poor. The stove provides too much heat, so the combustion
should be reduced. But always remember to make sure that there are lasting
flames until the wood becomes charcoal. If you want a weaker fire, stoke up
using less wood.
If you fire the stove using wet wood, a lot of the fuel's thermal energy will be
spent forcing the water out of the wood, without releasing any heat to the sto-
ve. This incomplete combustion results in a layer of soot being left in the stove,
pipe and chimney.
