3.2. Fuel

Only untreated firewood may be burned in the fireplace.
The wood should have a humidity of 15–20 % for optimal burning. Excessively moist wood will blacken
the glass door and the chimney with soot. Soot accumulation in the chimney also increases the
possibility of chimney fires. Burning moist wood causes more smoke and pollution, since the burning
can't advance cleanly. It also does not give off optimal heat, since part of the energy is used in turning
the moisture into steam. Firewood that is stored outdoors should be taken inside for a few days to
allow the surface moisture to evaporate.
Warning:
Do not use impregnated wood, chipboard, laminates, liquid fuels or anything similar even for starting
the fire. They may contain substances that will damage the fireplace and the chimney.
Wood chips or very small pieces of wood should not be used during the proper heating phase, since
they produce very high temperatures that may damage the fireplace. (Building material often contains
hazardous substances.) Only store as much wood close to the fireplace as you burn during a single
session. A small amount of wood can be stored in the container beneath the fireplace. The amount of
firewood stored in the storage space may not exceed the hight mark ( picture 1)
When wood is stored close to the fireplace, the safety distances mentioned in 2.5 must be kept.

3.2.1. Ignition

Check before lighting that the chimney is not obstructed. Open the chimney's damper plate.
Never use volatile ignition fluids to start the fire. It may cause flash fires that might endanger
the user and the product!
Shut off all devices that lower atmospheric pressure in the room such as range hoods and
mechanical ventilation.
The furnace should have a sufficiently large load of wood to ensure that a high enough temperature is
reached quickly. At low temperatures the burning process does not work correctly and the fireplace
and chimney are stained with soot. The fire may also go out, if the chimney does not build up enough
draught (-12Pa). Devices causing low pressure must be shut off or the window opened during the
ignition phase until the chimney develops enough draught to counter the low pressure.
During the ignition phase, the air regulators can be kept open or the feed door ajar. Once the fire is
going, you use the air regulators to adjust the burning to the level you want.
During the ignition phase, you use smaller firewood with a diameter of ca. 2-5cm with a length of 25-
30cm.
The load weighs about 1,5kg.
Always lay out the logs horizontally towards the rear of the furnace, with those on top slightly crossed.
Usually, a crumpled newspaper page, small, dry wood chips or an ignition piece are sufficient to get
the fire going.

3.2.2. Adjusting the heat output

The heat output can be adjusted as follows:The amount of combustion air (regulator lever under the
door) by adjusting the draught in the chimney with the damper plate or with the amount of wood.
Usually you do not need to add more than three logs at a time. (Large logs burn longer, of course.)
Never close the damper plate too far or the fireplace starts leaking smoke into the room.

3.2.3. Heating

During the proper heating phase the logs should have a length of 25-30cm and a diameter of 5-9cm.
A maximum loading should be 2.3 kg at a time, which is about three logs.
Do not put too much wood into the furnace.
Always lay out the logs horizontally towards the rear of the furnace, with those on top slightly crossed.
Once the wood has burnt down to embers, add a new load. You may spread the embers out on the
furnace floor.
Open the door carefully, balancing the furnace differential pressure, keeping the door slightly
open for a moment about 5-10cm before the door is opened completely.
