A pilot burner is a small gas burner used to ignite the main burner in a gas appliance, such as a furnace or water heater. It's like a tiny spark that starts a bigger fire, ensuring the main burner ignites safely and reliably. Unlike the main burner, the pilot burner operates continuously, providing a consistent ignition source. It's a crucial safety feature, preventing the buildup of gas that could lead to an explosion. The pilot burner is typically located near the main burner.
