Its original, custom-manufactured ignition system, contained in a box buried a few feet from the grave, controlled the flow of gas and oxygen to the flame and activated a 20,000-volt spark ignition electrode near the gas burner whenever the flame was extinguished. [73] In 2012, the automatic ignition system began clicking audibly.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
Auto reignition lowers the risk of gas leaks: if a flame goes out during operation, for example, from vibration or a gust of wind; due to misoperation—a user might not understand the "light" position must be maintained for about 0.5 to 2 seconds before turning the burner knob on fully.
