The arrangement includes a suction tube (10) with a first (12) and a second (14) section which are movable relative to each other in two operating positions (26,28), in such way, that the suction tube has a vertically accessible (32) suction aperture (30) in the first operating position, and a horizontally accessible (36) suction aperture in the second operating position. The arrangement includes a suction tube with a first and a second section, whereby the first section is connected at an exhaust fume tube, and the sections are movable relative to each other in two operating positions, in such way, that the suction tube has a vertically accessible suction aperture in the first operating position, and a horizontally accessible suction aperture in the second operating position. The first section is equipped with a first inlet aperture (34), which forms the suction aperture in one of the operating positions. The second section is equipped with a second inlet aperture which forms the suction aperture in the other operating position, in which the second section is plugged sealingly on the first inlet aperture.
