What are the three primary types of ignition sources that can be found on a gas stove?

The correct answer identifies the three primary types of ignition sources typically associated with gas stoves: pilot lights, manual ignition, and pilotless igniters.

Pilot lights are small, continuous flames that are always lit and serve as a reliable ignition source for gas burners. They automatically ignite the gas when the burner is turned on, making them a common feature in many traditional gas stoves.

Manual ignition refers to the process where the user physically ignites the gas burner using a match or lighter, highlighting the need for user intervention to start the flame. This method is straightforward but depends on the user's actions.

Pilotless igniters, often in the form of electric or electronic igniters, initiate combustion without the need for a continuously burning flame. These systems create a spark when the gas is turned on, effectively providing a modern and safe way to ignite gas burners.

These ignition sources are integral to gas stove operation and represent the primary methods through which gas is ignited for cooking, providing a comprehensive understanding for fire investigators regarding potential ignition sources in cases of fire incidents involving gas stoves.
