A flame powered intermittent pilot combustion controller may include a first power source and a second power source separate from the first power source, a thermal electric and/or photoelectric device, an igniter and a controller. The thermal electric and/or photoelectric device may charge the first power source when exposed to a flame. The controller and the igniter may receive power from the first power source when the first power source has sufficient available power, and may receive power from the second power source when the first power source does not have sufficient available power.

1. A flame powered intermittent pilot combustion controller for use with a gas-powered appliance, comprising: a first power source;a second power source;a thermal electric and/or photoelectric device that charges the first power source when the thermal electric and/or photoelectric device is exposed
1. A flame powered intermittent pilot combustion controller for use with a gas-powered appliance, comprising: a first power source;a second power source;a thermal electric and/or photoelectric device that charges the first power source when the thermal electric and/or photoelectric device is exposed to a flame;an igniter; anda controller;wherein the controller and the igniter receive power from the second power source for initial start-up after installation and after an extended duration of non-use of the associated gas-powered appliance after which the first power source does not have sufficient available power, and wherein the controller and the igniter receive power from the first power source and not the second power source during subsequent operation. 2. The flame powered intermittent pilot combustion controller of claim 1, wherein the first power source includes a capacitor. 3. The flame powered intermittent pilot combustion controller of claim 1, wherein the first power source includes a battery. 4. The flame powered intermittent pilot combustion controller of claim 1, wherein the flame powered intermittent pilot combustion controller is installed in the gas-powered appliance, and the second power source is pre-charged prior to installation of the gas-powered appliance at a customer site. 5. The flame powered intermittent pilot combustion controller of claim 4, wherein the second power source includes a battery. 6. The flame powered intermittent pilot combustion controller of claim 4, wherein the second power source includes a capacitor. 7. The flame powered intermittent pilot combustion controller of claim 4, wherein the second power source is rechargeable by the thermal electric and/or photoelectric device. 8. The flame powered intermittent pilot combustion controller of claim 1, wherein the second power source is removably coupled to the flame powered intermittent pilot combustion controller. 9. The flame powered intermittent pilot combustion controller of claim 1, wherein the second power source includes an AC to DC converter. 10. The flame powered intermittent pilot combustion controller of claim 1, wherein the second power source includes a hand powered electrical generator. 11. The flame powered intermittent pilot combustion controller of claim 1, wherein the flame powered intermittent pilot combustion controller services a burner assembly having a pilot flame burner and a main burner, and wherein the burner assembly does not provide a user with ready access to the pilot flame burner or the main burner. 12. The flame powered intermittent pilot combustion controller of claim 1, further comprising a momentary switch coupled to the second power source, wherein activation of the momentary switch by a user causes the controller to receive power from the second power source and to initiate a pilot flame by: commanding a gas valve to provide gas to a burner assembly; andactivating the igniter to ignite the pilot flame in the burner assembly. 13. A gas-powered appliance having an intermittent pilot ignition system, comprising: a power source;a burner assembly having an intermittent pilot flame, the burner assembly including a spark igniter;a rechargeable energy storage device, wherein the rechargeable energy storage device is configured to be charged using energy generated by a thermal electric and/or photoelectric device associated with the burner assembly;a controller coupled to the power source, the rechargeable energy storage device and the spark igniter of the burner assembly, wherein the controller initiates ignition of the pilot flame using the power source when the energy stored in the rechargeable energy storage device is below a threshold level, and uses energy from the rechargeable energy storage device and not the power source for subsequent operation when the energy stored in the rechargeable energy storage device is above the threshold level. 14. The gas-powered appliance of claim 13, wherein the power source is pre-charged prior to installation of the gas-powered appliance at a customer site. 15. The gas-powered appliance of claim 13, wherein the power source is removably coupled to the gas-powered appliance. 16. The gas-powered appliance of claim 15, wherein the power source includes an AC line adapter. 17. The gas-powered appliance of claim 13, wherein the power source includes a battery. 18. The gas-powered appliance of claim 13, wherein the power source is rechargeable using energy received from the thermal electric and/or photoelectric device associated with the burner assembly. 19. The gas-powered appliance of claim 13, further comprising a momentary switch, wherein the controller initiates the ignition of the pilot flame in response to a user pressing the momentary switch. 20. A flame powered intermittent pilot combustion control system for a gas-fired appliance, the system comprising: a pre-charged power source;a burner assembly having an inaccessible combustion chamber;a thermal electric and/or photoelectric device that directly and/or indirectly charges the pre-charged power source when the thermal electric and/or photoelectric device is exposed to a flame within the burner assembly;an igniter receiving power from the pre-charged power source, the igniter for igniting a flame in the burner assembly; anda controller, wherein the controller and the igniter receive power from the pre-charged power source for igniting a flame in the burner assembly for a first time after installation and/or after an extended duration of non-use, wherein the controller and the igniter receive power generated by the thermal electric and/or photoelectric device and not the pre-charged power source during subsequent operation of the gas-fired appliance. 21. The system of claim 20, further comprising a second power source separate from the pre-charged power source, wherein the controller and the igniter receive power from the second power source and not the pre-charged power source during subsequent operation of the gas-fired appliance, and wherein the second power source is charged via power generated by the thermal electric and/or photoelectric device. 22. A flame powered intermittent pilot combustion controller for use with a gas-powered appliance, comprising: a burner assembly for receiving a gas;an ignitor for igniting the gas of the burner assembly to produce a flame;a thermal electric and/or photoelectric device for generating power from the flame when the flame is present;a power source that is directly and/or indirectly charged by the power generated by thermal electric and/or photoelectric device when the flame is present;a controller, wherein the controller and the igniter receive power from the power source for igniting the flame of the burner assembly when the power source has a charge that exceeds a threshold level; andwherein the controller and the igniter receive power from an alternative power source and not the power source when the power source has a charge that does not exceed the threshold level. 23. The flame powered intermittent pilot combustion controller of claim 22, wherein the power source comprises a capacitor. 24. The flame powered intermittent pilot combustion controller of claim 22, wherein the power source comprises a re-chargeable battery. 25. The flame powered intermittent pilot combustion controller of claim 22, wherein the alternative power source comprises a battery. 26. The flame powered intermittent pilot combustion controller of claim 22, wherein the alternative power source is removable.
