This invention relates to the field of burner technology, specifically a burner for a gas-fired wall-hung boiler, comprising a rear mounting bracket and a venturi tube mounted on its front side. The front side of the venturi tube is connected to the front mounting bracket, and a temporary storage frame is fixed to the front side of the front mounting bracket.
