Abstract

A method for controlling a gas appliance or boiler to reduce the number of orifices positioned in corresponding gas feed lines to a burner (1 ), said gas being fed by a conduit in which a shut-off and/or turndown valve (7) is positioned, a flame sensing member (2) being provided in proximity to the burner, a control unit (5) being provided to command and control the correct operation of the appliance. This unit is connected to and controls the shut-off valve on the basis of the characteristics of the gas combustion in the burner and modifies the flow of this gas by intervening on the valve to achieve a combustion within predefined parameters independently of the type of gas fed, such orifices being at least partially replaced by a calibrated hole.
