The space between the slide rails 16 is marginally bigger than the base plate 14 of the burner body 10. The space between the slide rails 16 is complementary to the base plate 14 of the burner body 10. The lateral wings of the base plate 14 are engageable with the slide rails 16. The base plate 14 of the burner body 10 is slide-in and inserted between the slide rails 16. The burner body 10 is attachable at the metal sheet plate 12 by the sideward movement of said burner body 10, wherein the base plate 14 is inserted between the slide rails 16.

[0054] Moreover, the metal sheet plate 12 includes a tongue element 28 formed within a further punched hole. Said tongue element 28 extends parallel to the slide rails 16. Further, the tongue element 28 and the pair of slide rails 16 are arranged in series. The open end of the tongue element 28 is directed to the pair of slide rails 16. The tongue element 28 is inclined upwards, so that the height of said tongue element 28 decreases with the distance from the pair of slide rails 16.

[0055] Further, the metal sheet plate 12 includes an elongated cut-out 30 arranged directly beside the tongue element 28. Said elongated cut-out 30 extends parallel to the tongue element 28. The elongated cut-out 30 includes a first end portion 32 and a second end portion 34. The first end portion 32 is more distant from the pair of slide rails 16, while the second end portion 34 is closer to said pair of slide rails 16.
