how does this lite? it is not clear if it is a spark? descriptionand specs are not well done and useless. need to know how it lites?

Thank you for your question about this Piezo ignition kit. I am happy to explain how the igniter works. The igniter uses electricity to light the burner. When you press the igniter button, it creates a spark. The spark lights the thermocouple, which causes the burner to ignite and remain lit. I hope this explanation is helpful. Please let us know if you have any other questions.
