Abstract
An automatic pilot lighting system for unattended automatic lighting of a standing pilot may include a powered (e.g., battery powered, etc.) circuit. The powered circuit may include an analog timer circuit including a timer switch. A spark ignitor may be coupled with the timer switch. A temperature knob pilot momentary switch may be coupled with the timer switch. An ON/OFF switch may be coupled with the temperature knob pilot momentary switch and the timer switch. The ON/OFF switch may be configured to be operable for selectively disabling and enabling a power source. The analog timer circuit may be configured to be selectively activatable for applying voltage from the power source via the ON/OFF switch for pilot hold voltage and spark ignition for an amount of time sufficient to allow for unattended automatic lighting of the standing pilot and sufficient voltage generation to support standalone operation.
