ABSTRACT:
A device for creating an electrical potential, such as a piezoelectric igniter, is connected to a conductor that conducts current to a burn tube to create a spark that ignites the fuel in the burn tube. In one embodiment a gap is formed in the conductor. An insulator is located in the gap such that is can be selectively moved between an insulating position where the flow of electricity over the gap is prevented such that no spark is created in the burn tube and a non-insulating position where electricity is allowed to flow over the gap such that a spark is created in the burn tube. In another embodiment the piezoelectric igniter forms part of the electrical circuit and is in electrical conductive contact or proximity to an electrical conductor that forms part of the ignition circuit. An insulator may selectively located between the igniter and the conductor.
