Abstract (en)
[origin: EP0964326A1] The arrangement has a manually operated valve (7,8) in the gas feed line (6) and an electromagnetic valve (5,6) in the line that closes if the flame (10) is quenched. An ignition plug (3) at the burner point (4,10) ignites the gas and indicates whether unburnt gas is escaping. The electromagnetic valve and ignition plug are connected to an electronic controller (2) that activates the ignition plug if unburnt gas is escaping, and if ignition was not successful within a defined period or number of ignition pulses, closes the electromagnetic valve. An Independent claim is also included for an arrangement for implementing the method.
