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
gases in the wood do not ignite at the low temperature, but settle as soot (un-
burned 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 combu-
stion should be reduced. But always remember to make sure that there are la-
sting 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
stove. this incomplete combustion results in a layer of soot being left in the
stove, pipe and chimney.
The stove door should normally be opened gently the first - 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.
