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.
