ABSTRACT:
A burner system of the type in which a thermocouple or like EMF-generating sensor detects the presence of a pilot flame and controls a main fuel valve to hold the latter open as long as the pilot flame remains lit. According to the invention, the main valve is held open by a solenoid and a resistance is provided in circuit between the sensor and the solenoid to reduce the response time of the latter which results from the inductance contributed by the magnetic coil forming the solenoid.
