Gas outlet openings located along two rings of nozzles have mainly the same surface areas of sections, one gas injector, one Venturi tube that consists of a vertical convergent part and one expansion chamber for gas removal from one Venturi tube. The chamber is made so that gas can be supplied to two rings of nozzles of the burner. Burner includes the first cylindrical hollow annular element having the shape of a convergent part of the Venturi tube and intended to be installed vertically on the lower housing, and the second one into the planar hollow annular element suitable for installation on the first annular element and for the cover support. The lower ring of nozzles has the possibility of being provided with gas from an expansion chamber through a variety of channels that are mainly located within the external section of the first cylindrical annular element, and the upper side of openings in the lower ring of nozzles is restricted with the second annular element.
