Warning!
Allways secure enough combustion air during
operation. If the appliance is fitted with external air kit
this is taken care of. If not, room vents or a window
should be kept open / ajar.
Note that the air supply for the combustion also can
be too large and cause an uncontrollable fire that very
quickly heats up the whle 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.
The Firebox shall to be always closed except
during ignition, refueling and ash removal.
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:
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.

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