ABSTRACT:
An ignition and fuel supply system for gas-fueled heat radiators of the type comprising an upstream fuel feed (6), a safety valve (20) in the vicinity of the radiator, a pilot device (27) mounted on the radiator to allow reignition and a feed conduit (4) for the gas; the system includes a bypass (15) equipped with gas-expanding devices (14) providing a pressure less than the pressures in the heating areas, whereby the pilot flame device (27) may be fed from the same conduit (4) used for the heating areas; a selection valve (24) is arranged in the radiator injection conduit in order to be closed at the pressure of the pilot flame; an ignition branch line (16) is arranged as a shunt of the upstream feed means (6) in order to supply gas at a pressure exceeding the pressures of the heating modes at the time an electrical igniter (19) is actuated to assure electrical ignition of the radiator.
