Frigidaire FG7MQ Product information

Hello! I've reviewed the Ladder Diagram for Single Stage furnaces. This document details the wiring connections for various components within the system, including the blower motor, flame sensor, and transformer. I'm ready to assist with any questions you have about this schematic or its components.
What does 'L1' stand for in the diagram?

What is the purpose of the flame sensor?

What does the 'XFORMER' represent in the diagram ?
