wood
Your first heating session
The lacquer will be fully hardened after the stove has been used, and the door and the ashpan should be
opened very carefully as there will otherwise be a risk that the gaskets will stick to the lacquer. In addi-
tion the lacquer may initially give off an unpleasant odour, so make sure that the room is well ventilated.
Tips about fuel:
Approved fuel types
The insert is EN approved for combustion of wood only. It is recommended to use dried chopped wood
with a water content of a maximum of 18%. Stoking a fire with wet wood results in soot, environmental
problems, and a less efficient fuel economy.
Recommended wood types
All types of wood, for instance birch, beech, oak, elm, ash, conifers, and fruit trees can be used as fuel in
your insert. The great difference is not in the fuel value, but in the weight of the wood types per cubic
metre. Beech weighs more per m3 of wood than common spruce, for instance. This is why more com-
mon spruce is required, in terms of volume, to obtain an amount of heat similar to that of beech. Heavy
types of wood such as ash, beech, oak and elm are generally not that easy to light up. In addition, they
burn more slowly and give off more embers. Light types of wood such as birch, maple, spruce and pine
are more easy to light up. They burn faster and give off fewer ambers. You may therefore take advantage
of the light types of wood for lighting and use the heavier types of wood to ensure a longer burning time..
Banned fuel types
It is not allowed to stoke a fire with the following: printed matter, plywood, plastic, rubber, fluid fuels,
and rubbish such as milk cartons, lacquered wood or impregnated wood and fossil fuels. The reason that
you should not apply any of the above is that during combustion they develop substances that are health
hazardous and harmful to the environment. These substances could also damage your insert and chimney,
rendering the product warranty void.
Storage of wood
A moisture content of 12-18% is achieved by storing recently felled wood outdoors under a lean-to
for at least one year, preferably 2 years. Wood stored indoors has a tendency to become too dry and
combust too quickly. However, it might be advantageous to store fuel for lighting a fire indoors for a few
days prior to use.
It is recommended to purchase a wood moisture meter to continuously check that the firewood has
the correct moisture content before using it for firing.Split the wood and measure the moisture content
of the split surfaces.
Recommended dimensions
The dimensions of the fuel are important to good combustion. The dimensions should be as follows:
Fuel type Length in cm Diameter in cm
Wood for kindling a fire (finely chopped) 25-33 2-5
Chopped wood 30-50 7-9
