The invention relates to a gas consumption reducing device, for independent gas-fired heaters, primarily for gas convectors and gas-fired fireplaces, which has an operator device, a clack-valve controlling the combustion air flow, and a multipositional gas tap with shutter. The invention is characterized in that in all positions the gas quantity is set by calibrated gas by-pass openings (14, 15) and a calibrated injector (19), the shutter (2) of the multipositional gas tap (1) is connected to the moving device (5) of the clack-valve (4) controlling the combustion air (3) flow in a correlated manner, and the position of every clack-valve (4) working with the gas tap (1) is associated with corresponding calibrated gas by-pass capacity. ? |
