<p>The invention relates to a gas regulating fixture in which the adjustment of the gas quantity can be varied. For this purpose, the application of a remote control should additionally be made possible. According to the invention, the production expenses and the construction size are kept as small as possible. A switch of a known type with a springable element is arranged in the housing after the main valve. Said switch is connected to two valves and effects a modulating control with erratic-formed on-of switching in the partial load area. Said switch can be actuated by a longitudinally movable tappet projecting outward from the gas conducting housing and whose position can be changed via a control element. The control element can thus be adjusted manually and/or by means of an actuating unit comprised of an electric drive motor coupled to a battery. The inventive gas regulating fixture for a gas heated chimney stove or the like serves to influence the magnitude of the visible flames especially for decorative reasons.</p>
