For Heater Repair Tech Only
Reason: This error indicates that the AFRO circuit has detected a flame rollout while the gas valve is not energised, and flame is not expected. Service Check List: • Check that the pilot AFRO bar or wiring is not shorted to Earth. • Check if a flame is present with the unit turned OFF. • Check the gas valve is not jammed open due to malfunction, obstruction or blockage. • Check if the 24 Volt power supply to the valve has been turned OFF, as expected in the normal operation.
