- put the plug of the power cable into the mains socket (230V 50Hz)
- open the top part of the heater housing and remove the cover of the combustion chamber, then take out
the cylinder and ring (in the case of necessity, clean the combustion pan and base on which it is placed,
but also the whole combustion chamber with a sleeve and the ring)
- check whether the furnace pan is cool and clean, then pour about 250 ml of fuel oil or diesel oil

- after about 10-15 minutes, depending on the room temperature, the fuel pump and the fan will be
switched on, and at the same time, the yellow diode for pump operation will be back-lit, the furnace
will start to operate on the first gear with a decreased efficiency (22 kW; burning 1.85 kg/h), it may
operate continuously in this condition, the second gear with an increased efficiency (30 kW: burning
2.55 kg/h) may be switched on (marked with "+" symbol) after 30 minutes from the start of the
