* when working at average load (50% of rated power)/ rated load
** if manufacturer recommendations regarding heating water temperature ranges are
not observed, boiler must be obligatory connected to central heating system equipped with three- or four – ways
valve, protecting against so called „ low temperatures corrosion”
C* handle use to transport a boiler ( dimension 150 mm)
