4. Instructions for use
4.1. Fuel
The only suitable fuels for this stove are wood and brown coal briquettes. No other
fuels are allowed to be burnt, as they can inflict serious damage to your stove.
Do not burn any treated wood either, such as scrap wood, dyed wood, impregnated
or preserved wood, plywood or chipboard. The fumes of these, as of synthetic mate-
rials, old papers and household waste, are highly polluting for both your stove and
your chimney, and for the environment. They also could cause chimney fires.
Wood
Hard woods, such as oak, birch- and fruit-trees, are the ideal fuels for your stove.
The wood must have dried for at least two years in a covered and well-ventilated
place. Split logs will dry faster. Dry wood should contain no more than twenty pe r-
cent moisture.
Wet logs are unsuitable for burning, as they do not produce enough heat and all of
the energy is lost in the process of evaporation. Moreover, the burning of wet wood
causes badly smelling gases to be released and a thick layer of tar will deposit on
the stove panels and in the chimney.
Brown coal briquettes
Brown coal briquettes burn in more or less the same way as wood does. You should
only burn briquettes on a bed of charcoal in your stove.
4.2. Lighting a fire
In order to create sufficie nt draught and to prevent smoke from being emitted into
the room, the chimney should be warm enough before lighting a fire. A cold chim-
ney can be heated up by lighting a ball of paper above the fire plate.
To kindle the fire in the stove you can use paper and/or firelighters and small pieces
of wood.
Slightly open the door and pull the air slides wide
open. See the sketch on how to use the air slides.
It is important that the kindled fire should burn in-
tensely. You can then throw larger pieces of wood
onto the fire, and close the doors. When the fire has
eventually stabilized and is glowing enough, you can
put the logs or the brown coal briquettes on the fire.
4.3. Burning wood
The best way to control the fire is to completely close
the lower air slide, which you use to get the fire
started, and to regulate the air supply with the upper
air slide only. In case the air supply through the upper
slide seems insufficient, or if you would like to fan the
fire, you can partially open the lower air slide for a
while.
Always keep the stove doors tightly closed. Never let
the doors open when the fire is burning.
Add extra fuel when necessary. Never add too much fuel. It is best to fill the stove
for one third and to top it up on a regular basis.
