         2 . The gas burner assembly according to  claim 1 , wherein each of the burner base and injector base is manufactured from a thin sheet of material. 
     
     
         3 . The gas burner assembly according to  claim 2 , wherein the thin sheet of material is a sheet metal transformed by stamping. 
     
     
         4 . The gas burner assembly according to  claim 1 , wherein the burner base includes at least one support flange and the injector base includes at least one engagement flange, the injector base being coupled to the burner base by an overlapping of the at least one support flange with the at least one engagement flange. 
     
     
         5 . The gas burner assembly according to  claim 1 , wherein the injector base includes at least one support flange and the burner base includes at least one engagement flange, the injector base being coupled to the burner base by an overlapping of the at least one support flange with the at least one engagement flange. 
     
     
         6 . The gas burner assembly according to  claim 4 , wherein the at least one support flange is welded to the at least one engagement flange. 
     
     
         7 . The gas burner assembly according to  claim 5 , wherein the at least one support flange is welded to the at least one engagement flange. 
     
     
         8 . The gas burner assembly according to  claim 1 , wherein the burner base comprises a flat horizontal surface from which the vertically upward projecting perimetral wall projects. 
     
     
         9 . The gas burner assembly according to  claim 1 , wherein the injector base comprises a through hole that is concentrically aligned with the hole in the burner base, the injector being supported in the through hole. 
     
     
         10 . The gas burner assembly according to  claim 9 , further comprising a mouth of a gas conduit being fluidly coupled to the injector and coupled with injector base. 
     
     
         11 . The gas burner assembly according to  claim 1 , wherein the injector base includes at least one attachment arm attaching the injector base with the burner base. 
     
     
         12 . The gas burner assembly according to  claim 1 , wherein the injector base includes a radially extending support arm to which is attached a spark electrode that extends vertically upward from the injector base. 
     
     
         13 . The gas burner assembly according to  claim 12 , wherein the support arm includes a plurality of holes arranged in a row along a length of the support arm, each of the plurality of holes configured to support the spark electrode. 
     
     
         14 . The gas burner assembly according to  claim 1 , wherein the burner base includes at least one primary air hole, the at least one primary air hole being in fluid communication with the hole of the burner base.
