Heating with wood – for the sake of the environment
Wood is produced from the natural forces of the earth and
the sun. A natural fuel that is constantly regenerated and
decomposes and burns in a CO
2
neutral manner.
The shortage of raw materials and the greenhouse effect
caused by the use of fossil fuels such as crude oil and
natural gas can be counteracted effectively with a modern
biomass heating. system.
A sustainable future for energy uses the most modern technology and a valuable biogenic fuel: wood.
Physical process of wood combustion
The wood is initially heated and dried at approx. 100°C. As the temperature increases gaseous
materials (water and oxygen) escape. Depending on the quality of the fuel the flashpoint lies
between 230°C and 280°C. Solid materials (cellulose, lignin, etc.) are then converted into a gaseous
state. Pyrolysis is the thermal separation of materials and a change in the aggregate state in the
temperature range between 180°C and 450°C. The decomposition of the wood is designated as
primary combustion (endothermal process). With the addition of pre-heated secondary air the wood
gases are now burned in the post combustion zone (exothermal process.)
Negative pressure (by means of a suction fan) directs the combustion air via the automatic primary
and secondary air flaps.

Initial commissioning
Initial commissioning can only be carried out by Lohberger Heiztechnik trained personnel. The
following list is an extract of the points that the technician will follow when carrying out the initial
commissioning.
Important information:
Ensure children are supervised in the vicinity of the boiler: the boiler is not childproof!
Prior to initial commissioning all connections (water and flue pipe connection, electrical) on the
system must be checked. For a cold boiler the system pressure must be at least 1.5 up to max. 2
bar.
Always keep the combustion chamber door and ash door closed even when the appliance is cold.
Always use a heat-resistant glove when working on the system.
Pellets may not be loaded into the hopper/pellet storage space until installation has been
completed in accordance with the assembly and installation instructions.
Always ensure the central heating room is well ventilated.
Before operation boilers must always be filled with water and connected to a heating system.
Safety devices must not be bypassed, turned off or removed.
Flue: the flue must not be obstructed in any way. Have the flue inspect and clean by the chimney
sweep.
Carry out relay test.
Check the auger radius of the coreless auger (min. 1.2 m).
Release hydraulic components and make system-specific settings.
The safety devices must be operational.
Check the safety valve and the discharge.
Check the valve of the thermal discharge safety device and the discharge.
Carry out heating test.
Adjustment measurement, measure flue draught.
