Which ignition method does NOT include a pilot light?

The method of ignition that does not include a pilot light is the one described as having pilotless igniters. Pilotless igniters operate without a continuously burning flame, like a pilot light, to ignite the main burner. Instead, they utilize various technology such as electric sparks or hot surfaces to create the necessary heat to ignite the fuel.

This method offers advantages such as improved efficiency and safety, as there is no ongoing open flame that can pose a risk. It is important in applications where a steady ignition source is not feasible or safe, making it a preferred choice in many modern appliances.

In contrast, the other methods mentioned either include or rely on a pilot light for operation, which does not apply to pilotless igniters.
