Abstract

The invention relates especially to automatic gas burning apparatus for domestic cooking ovens and comprises a first thermo-electric device 11 spaced from the principal burner 13, a subsidiary burner 31 for heating the first device 11, a second thermo-electric device 12 arranged to be heated by burner 13 alone and circuitry 44 for supplying current from either the first or the second device 11, 12 to a safety valve 10 in the gas conduit 14 to burner 13, valve 10 being closed unless held open manually or maintained in the open condition, after manual opening, by a supply of thermo-electrically generated current, a time controlled valve 41 in the gas conduit 14 being provided with a switch 32 for actuating ignition of burner 13 on operation of valve 41 to allow gas to be supplied to burner 13 and for preventing the device 11 from supplying current to valve 10 while valve 41 is allowing gas to be supplied to burner 13. Thus, valve 10 is controlled by device 12 during the burning of gas at the principal gas burner 13. <IMAGE>
