one third and to add regularly. Always open the filling door slowly and always open it
for the shortest time possible. Before adding, make sure that the charcoal base is
distributed equally over the stoking surface. If needed, open the primary air valve for a
little while.
If the wood is piled up loosely, it will burn very quickly because the oxygen will reach
every piece of wood easily. This piling is used when one wants to stoke in a short time.
When the wood is piled more compactly, it will burn slower as the air can only reach
particular pieces of wood. It is best to use this piling method if one wants to stoke for a
longer period of time

Lighting a fire
In order to create sufficient draught and to
prevent smoke from being emitted into the
room, the chimney sh ould be warm enough
before lighting a fire. A cold chimney can be
heated up by lighting a ball of paper above
the fire plate or at the back of the bunker.
To kindle the fire in the stove you can use
paper and/or firelighters and small pieces of
wood.
Slightly open the door and turn the air slides
wide open.
It is important that the kindled fire should
burn intensely. You can then throw larger
pieces of wood onto the fire, and close the
door. When the fire has eventually stabilized
and is glowing enough, you can put the logs
or the brown coal briquettes or the coals on
the fire.

Burning wood
The best management of the hearth can be
obtained by shutting off the primary airflow (1)
completely
(=
regulating the air intake with secondary
airflow (2). If this management proves to be
insufficient, or in order to fan the fire, one can
temporarily open the primary airflow for extra
air intake. Make sure that the furnace door is
always shut adequately.
Never stoke with an open door.
Add fuel timely. Do not add too much fuel at
once. It is best to fill the hearth to maximally
