Abstract: Apparatus for igniting combustible fuel discharged from an outlet in a burner tube comprises a dielectric support within which are an ignition electrode and a ground electrode projecting beyond the support and which are spaced from one another a distance to form a gap which may be traversed by sparks generated by the ignition electrode. A fuel concentrator plate is carried by the ground electrode and partially embraces the ignition electrode adjacent the gap. The electrode support is mounted directly on the burner tube in a position to enable the concentrator plate to intercept fuel discharged from the outlet and concentrate the fuel in the zone of the gap.

Abstract: A method and apparatus for relighting a gas oven following interruption in the operation thereof due to a temporary failure or reduction in the energy level of a source of electric energy comprises instantaneously disconnecting the delivery of pressurized gas to the oven in response to a reduction in the level of the electric energy, slowly reducing the pressure of gas in the delivery system, monitoring the pressure of the gas, and restoring the delivery of fuel to the oven only if the energy supply is restored to a proper level within a short period of time and prior to a predetermined reduction of the gas pressure.
