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.
Warning:
Make sure the insert is not overheated it can cause
irreparable damage to the product. Such damage is
not covered by the warranty.

Warning:
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 too high.
