How do you purge air from a oil burner?

To purge air from an oil burner, first, ensure the burner is turned off and the oil supply valve is closed. Next, locate the bleed valve on the fuel pump and place a container underneath to catch any oil. Open the bleed valve slightly and allow oil to flow until it is free of air bubbles, then close the valve. Finally, turn the burner back on and check for proper operation.
