A thermoelectric safety assembly that includes a thermocouple configured to detect a flame in a burner and, in response to detecting the flame, generating an electrical voltage. The assembly includes an electromagnetic valve electrically connected to the thermocouple, and a transistor electrically connected between the thermocouple and the electromagnetic valve. The electromagnetic valve is arranged electrically connected with a field-effect transistor. The assembly also includes a voltage booster configured to power the transistor, the transistor being connected in parallel with the voltage booster. An output terminal of the voltage booster is arranged connected with a gate terminal of the transistor, the voltage booster being configured to boost the electrical voltage generated in the thermocouple, an electrical voltage being obtained that is capable of keeping the transistor closed such that the electromagnetic valve is energized.
