The end walls 8 and 9 are coupled to the lateral wall 7 so as to form the casing 2, which delimits a combustion fumes circulation chamber. In this specific case, the end wall 9 has a central opening 10 for housing a burner with a cylindrical shape, not shown in the accompanying Figures, which is partly arranged inside the combustion fumes circulation chamber.
