Method and system for starting an intermittent flame-powered pilot combustion system

A gas-powered appliance having a flame powered intermittent pilot ignition system, comprising:

• a pre-charged power source;
• a rechargeable power source;
• a burner assembly comprising an ignitor, wherein the ignitor is configured to:
• receive power from the rechargeable power source;
• and
• ignite the burner assembly to produce a pilot flame;
• a thermal electric and/or photoelectric device configured to charge the rechargeable power source in response to the thermal electric and/or photoelectric device being exposed to the pilot flame;
• and
• a controller configured to:
• receive power from the pre-charged power source;
• and
• control the ignitor to ignite the burner assembly to produce the pilot flame.

A method of igniting a pilot flame of a gas-powered appliance having a flame powered intermittent pilot ignition system, the method comprising:

• receiving, by a controller, power from a pre-charged power source;
• causing, by the controller, an ignitor to use power from the pre-charged power source to ignite the pilot flame of the gas-powered appliance in a first ignition following installation of the gas-powered appliance;
• and
• causing, by the controller, the ignitor to use power from a rechargeable power source to ignite the pilot flame of the gas-powered appliance after the first ignition.
