Error code EA (flame not detected on a RD532i Boiler?

Gas ran out on a meter card while shower on. Water ran cold. When added new credit on card and hit reset button it tries to fire up the boiler but fails and shows Error Code EA. Flame not detected is the official prognosis in manual and the red light is out beside pilot light sign. How do I light pilot light and make sure boiler is working? 3 kids in the house and can't really wait till the morning to call someone out. Thanks in advance
