What type of pilot is commonly used on a direct ignition system?

In direct ignition systems, there are no pilots used at all. Instead, these systems employ electronic ignition to light the burner. When a call for heat is initiated, a spark or flame sensor activates, providing a more efficient and reliable means of ignition without the need for a continuous or intermittent pilot flame. This approach not only enhances energy efficiency by eliminating the constant gas supply that pilots typically require, but it also simplifies the system by reducing component complexity and potential failure points. As a result, direct ignition systems often demonstrate improved safety and performance compared to those reliant on traditional pilot lights.
