Instructions for use
4.1. Fuel
The only suitable fuels for this stove are wood, brown coal briquettes and charcoal.
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 per-
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.
Charcoal
There are several categories of anthracite coal. Some characteristics may be legally
determined. For instance anthracite “A” has to contain less than 10% of volatile sub-
stances, anthracite “B” less than 12%. The ash content may range from 3 to 13%.
For a good operation of your appliance, the use of anthracite “A” with a low ash con-
tent is recommended. A combustible with a high ash content has a lower net heating
value. Moreover, the ashes have to be removed more frequently and the fire will go
out faster. The recommended calibre is 12/22 or 20/30.
4.2.
Lighting a fire
In order to create sufficient draught and to prevent
smoke from being emitted into the room, the chimney
should be warm enough before lighting a fire. A cold
chimney 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 intensely.
You can then throw larger pieces of wood onto the fire,
and close the doors. When the fire has stabilized and is
glowing enough, you can put the logs, the charcoal or the
brown coal briquettes on the fire.
