Storing of wood
In order to ensure that the wood is dry, the tree should
be cut in winter and stored during the summer, covered
and in a location with adequate ventilation. The wood
pile must never be covered by a tarpaulin lying on the
ground as the tarpaulin will then act as a sealed lid that
will prevent the wood from drying. Always keep a small
amount of wood indoors for a few days before use so
that moisture in the surface of the wood can evaporate.
Usage
Not enough air to the combustion may cause the glass
to soot. Hence, supply the fire with air just after the
wood is added, so that the flames and gases in the
combustion chamber are properly burnt. Open the air
vent and have the door slightly ajar in order for the
flames to establish properly on the wood.
Note that the air supply for the combustion also can
be too large and cause an uncontrollable fire that very
quickly heats up the whole combustion chamber to an
extremely high temperature (when using with a closed
or nearly closed door). For this reason you should never
fill the combustion chamber completely with wood.
It is recommended to keep an even fire with a small
amount of wood. Too many logs put on hot ember, may
result in combustion air starvation, and the gases will
be released unburnt. For this reason it is important to
increase the air supply just after adding logs.
Choice of fuel
All types of wood, such as birch, beech, oak, elm, ash
and fruit trees, can be used as fuel in the insert. Wood
species have different degrees of density - the more
dense the wood is, the higher the energy value. Beech,
oak and birch has the highest density.
Attention! We do not recommend using fuel
briquettes/ compact wood in our products. Use of
such fuel may cause the product to overheat and
exceed the temperatures determined safe.
Burning briquettes/ compact wood is done so at
your own risk and only small amounts (max 1/3 of
normal load) should be used for each load.

NEVER use impregnated wood, painted wood,
plywood, chipboard, rubbish, milk cartons,
printed material or similar. If any of these items
are used as fuel the warranty is invalid.
Common to these materials is that during
combustion they can form hydrochloric
acid and heavy metals that are harmful to
the environment, yourself and the insert.
Hydrochloric acid can also corrode the steel in
the chimney or masonry in a masonry chimney.
Also, avoid burning with bark, sawdust or other
extremely fine wood, apart from when lighting
a fire. This form of fuel can easily cause a
flashover that can lead to temperatures that are
Make sure the insert is not overheated - it can
cause irreparable damage to the product. Such
damage is not covered by the warranty.
