Most suitable for use in open fireplaces are all types of hardwood, like beech or birch. Softwood species
(conifers) have a closed-cell structure, which is bursting during combustion, causing glowing embers to be
thrown out of the fireplace. Hardwood is burning more calm and evenly.
You can control the heat radiation intensity by volume of wood and the intervals for stoking up.
Adjusting the heat by reducing the volume of combustion air is wrong! If there is not enough combustion air
available, the energy contained in firewood cannot be completely released. At the same time, the emissions
are rising due to unburned particles.
Too much of firewood or inappropriate fuel types can cause overheating and damage.
No kind of waste shall be burned in a fireplace!
Waste on fire = Toxins in your garden!
Never use combustible fluids, like petrol or alcohol as aids for lighting fire!
Mind the waste incineration ban!
Remember to use only the recommended fuels described in this User Guide. Improper, not
recommended fuels cannot be burned in a fireplace.

SEASONING OF FIREWOOD
After cutting the trees, the wood should be seasoned in an open and dry place and protected from rain and
snow.
The best time to cut trees is from December till February.
Firewood should be stored under a roof or in a ventilated building (shed). Do not store freshly cut wood in the
cellar or in a closed area. It can’t dry there.
