9Begins Pilot Trial For Ignition and turns on PTFI LED

9The pilot gas solenoid valve is opened, the spark igniter begins sparking, and the flamerod sensor watches for flame initiation

9When flame is established, the FLAME LED is illuminated and main valve opens and the FSC powers the Maxitrol system and gas flow begins modulating

9The FSC monitors the flame while the Maxitrol system adjusts to the selected temperature

The Maxitrol system checks the discharge air temperature (and the room temperature for the Maxitrol

44)and regulates the gas going to the burner to satisfy the temperature setting. The Maxitrol system will modulate the main burner gas from 100% down to 5% as needed.
