Abstract
An intermittent pulsing ignition system for gas fired devices includes a pulser assembly having a predetermined on/off cycle, providing full wave alternating current during the on cycle and half wave current during the off cycle, to an electrical ignition element. The full wave current is sufficient to heat the ignition element to the ignition temperature of the gas and the half wave current permits the ignition element to cool during the off cycle thereby prolonging its useful life.
