Abrégé

The present invention relates to an arrangement for adjusting the operation of a valve (2) in a flue (4) in a chimney. This arrangement comprises at least one closing means (9) arranged in connection with the flue, the closing means preventing an air flow in the flue (4) in its first extreme position and opening the flue for an air flow therein in its second extreme position. The operation of this closing means (9) is arranged to be controlled by a damper (10) movable in a smoke duct (3). The control is achieved in such a way that the movement of the damper generates a mechanical force effect which exerts on the closing means (9) a force causing a change in the state of the closing means. Resulting from the state change, the closing means becomes positioned either in a position opening a flow opening (13) or in a position closing it.
