heating system and releases energy when the boiler does not operate, but
there is thermal energy consumption by the heating system. The heat
energy, contained in the heat accumulator is utilized both for heating
purposes as well as heating domestic hot water (see figure 4.5);

Fuel hopper charging
At nominal operation mode of the boiler, it should be charged with fuel
periodically. The fuel charging procedure is described below:
o
Open the ignition flap (by pulling the level of the ignition flap – see the
figure below), the flue gases in the fuel hopper will be released to the
chimney through this flap;
Figure 5.6. Position of the lever, which controls the position of the ignition flap
– the flap is opened at the position, shown on the figure above;
o
Wait for 5 - 10 seconds, open the door of the fuel hopper chamber The
opening process of the door should be performed in steps – first half-open
the door , so the ambient air will penetrate the chamber, do not allow flue
gases to be released out of the chamber to the ambient atmosphere;
o
Open the door of the fuel hopper chamber and charge with wood logs. It’s
good idea to have the wood logs arranged, so to make easy the fuel
charging process. ATTENTION : have preventive measures not to get
burned, nor got suffocated with the flue gases, released out of the fuel
chamber – wear self-protecting clothes, etc. The fuel should be charged in
a manner, that it should be arranged in the chamber, so the volume of the
chamber to be optimally filled with wood logs. Place the wood logs in
longitudinal manner. Before charging the chamber with new fuel, it is
recommended to make stirring of the chars at the orifice of the burner, in
