Important Information for System Operators
1.4.2 Wood gasification boiler
The boiler is suited for burning wood in the form of unprocessed firewood. The water content of the fuel must be
between 15 – 25 %. General guidline: wood should be stored for appr. 2 years. The effects of any deviations from
these guidelines should be taken into account.
– ½ m split logs:
50 – 53 cm long, approx. 8 to max. 15 cm edge length.
If lengths vary dramatically ( e.g., 1/3
m) undertake adapted filling!
Round logs
must always have a
Ø of more than 8 cm!
– Wood briquettes: ignition with coarse wood briquettes, according to ÖNORM M7135 or DIN 51731.
– Residual wood: ignition of residual wood such as timber, boards, posts, etc. is permitted, as long as the
wood has not been treated with wood preservers or other chemicals containing halogenated
organic compounds or heavy metals (among such prohibited residual materials are, in par-
ticular, construction and demolition waste). Wood fuel must be added as appropriate to the
material!
Unsuitable fuels:
– Solid fossil fuels: black coal, brown coal, coke, peat, etc.
– Wood chips, wood shavings, pellets, straw, grain, wood from short-rotation forestry etc.
– Do not use plastics, PVC panels, sawdust, impregnated/glued wood residues, or similar – these cause boiler
corrosion and are prohibited by the Federal Air Purity Act.
Attention!
Do not use fuels with high dust levels, such as grinding dust or sawdust – risk of explosion!
1.5 Commissioning and maintenance
Windhager Customer Service or one of our customer service partners must commission your new boiler. All
systems will be thoroughly checked, and you will also benefit from detailed information provided by the system
installer. Installation and routine maintenance performed by Windhager Customer Service or a customer ser-
vice partner will guarantee the optimal performance and service life of your boiler system. This will also ensure
that this technologically advanced system provides the benefits of safe, environmentally friendly, and energy-
saving operation.
The following preconditions must be met before ordering the boiler commissioning:
1.) Boiler installed correctly.
2.) System fully electrically wired.
3.) System rinsed, filled, and vented – heat demand must be present.
4.) Boiler connected to domestic water and filled.
5.) Sufficient quantity of fuel available (pellets, split logs, oil, or gas).
6.) The customer must be present during commissioning.
The commissioning cannot be carried out if any of these items are incomplete or neglected. The customer
will be charged for any unnecessary costs arising as a result.
Start-up and maintenance by Windhager customer service or a customer service partner are part of the
guarantee requirements of the enclosed “guarantee limitations”.
Note!
Wood gasification boiler: When the boiler is heated up for the first time, unpleasant smells may
occur from gas emissions due insulation or paint residue being burnt off. Therefore, ensure that
the boiler room/installation room is well vented. Condensation may also form near the coasting
surfaces, and the combustion chamber temperature may only increase after a delay.
Note!
Pellet boiler: During the first few weeks after start-up, condensation can occur in the combustion
chamber, ash chamber, and on the heating surfaces. This has no effect on the boiler‘s function and
service life.
