Abstract
A control system for the ignition of a gas burner that include an electromagnetic valve having a first coil and a second coil, the activation of the first and second coils controlling the flow of gas through the electromagnetic valve. An ignition element which is designed to be heated until it reaches the gas combustion temperature of the gas delivered to the burner is disposed electrically in series with the first coil, the ignition element and first coil forming a branch. The control system also includes an auxiliary electromagnetic valve with a coil, the activation of the coil controlling the flow of gas through the auxiliary electromagnetic valve. The flow of gas towards the burner is allowed when both the electromagnetic valve and the auxiliary electromagnetic valve are open.
