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 the 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 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 they
during combustion can form hydrochloric
acid and heavy metals that are harmful to the
environment, you and the insert. Hydrochloric
acid can also corrode the steel in the chimney
or masonry in a masonry chimney. Also, avoid
firing 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.
