The above settings are given for different types of coal fuel. Hazelnut charcoal type can burn in an
automatic combustion pot. By changing the supplied feeding and waiting settings for this, you can
catch the most suitable burning setting for the boiler.
When there is no coal in the fire pot, the top cover can be opened and wood can be used. Since the
wood is thrown by hand, it is necessary to be careful against the risk of burning hands while throwing
wood into the boiler. It is important not to fill the entire chamber with fuel in manual wood feeding.
If the entire chamber is filled with wood, as the heat transfer areas will be covered with fuel, a
decrease in boiler efficiency can be observed.
The values given according to the capacities in the table will vary depending on the degree of
insulation in the environment where the boiler is heated, the chimney pull, and the thermal
comfort of the space.
