F04 Fault Code - FLUE SENSOR

This display indicates that the flue temperature sensor of the boiler has failed. This is a serious safety issue. The boiler will not restart until the sensor is replaced by a technician and he pushes the RESET button on the display. This situation is indicated by the red light and the flashing word LOCKOUT on the display. During this lockout fault, the pump will be on as indicated on the second line of the display.
