A holder assembly for a burner of a gas cooking appliance. According to one embodiment, the assembly includes a gas conduit, an injector partially housed at a first end of the gas conduit. The assembly further includes a burner base and an injector base arranged below the burner base, the injector base having a through hole in which portion of the first end of the gas conduit is arranged such that the injector is oriented towards the burner base. The through hole of the injector base has at least one non-circular coupling segment, and the gas conduit has a plastically deformed intermediate segment covering the coupling segment.

Example embodiments relate to a burner unit for combusting an air-fuel mixture. The burner unit includes an air supply dome having recesses which have a larger width on an inside of the air supply dome than on an outside.

A device for cleaning a tip of a furnace burner including a support tube of axis X intended to pass through the burner to have the burner passing through it and where the support tube includes a metal cable connected at one of its ends to a scraper and at the other end to a system for setting and maintaining the position of the scraper, in that the scraper is articulated to on the support tube between a first position aligned with the axis X in the continuation of the support tube and a second position perpendicular to the axis X, in that the scraper has a chamfered part on its profile and in that the support tube is connected to a rotation means for setting rotating the entire whole device in rotation. It can be set in place and manipulated from the rear of the burner, thereby ensuring a good level of safety for interventions such that a rotational and/or translational movement about the tip of the burner allows the concretions to be cleaned off effectively whatever their nature (shape, hardness, etc.) and their position.
