What type of pilot allows for continuous ignition during main burner operation?

Standing pilot
Intermittent pilot
Electronic pilot
Variable pilot

The correct answer is: Standing pilot

The type of pilot that allows for continuous ignition during main burner operation is the standing pilot. A standing pilot is a small flame that remains lit at all times, providing continuous ignition for the main burner when it is activated. This design ensures that the main gas burner can ignite instantly without needing to relight the pilot each time the main burner is called for heat. In contrast, the other types of pilots operate differently. An intermittent pilot, for instance, only ignites when there is a call for heat, which means it is not continuously lit. An electronic pilot also relies on an ignitor that activates only during main burner operation but does so electronically, meaning it is not continuously burning. Lastly, a variable pilot refers to a type of pilot that can adjust its flame size but does not inherently imply continuous burning like a standing pilot. Therefore, the standing pilot is the correct answer as it meets the requirement for continuous ignition during the operation of the main burner.
