Indicates that there is a possibility that the level of CO in ambient atmosphere is too high.
This error will usually be generated when there had been a good electronic flame signal, and the temperature
of the thermocouple was hot enough, but has since become cooler.
Possible reasons:-
• Problems with chimney, or room, air inlets (insufficient air circulation).
• Unstable pilot flame (e.g. wind, unsuitable thermocouple position).
• Contaminated pilot (poor flame to thermocouple).
• Poor position of ceramic parts (e.g. coal, logs, or matrix).
• Intermittent failure in thermocouple when hot (inner wire in head perhaps making contact when cold,
but not when hot).
Indicates that the ambient temperature around the gas control valve within the fire has exceeded 72°C.
NOTE: This error protects the fireplace and valve from excessive temperatures.
Possible reasons:-
• Faulty installation of the fire (not sealed correctly in fire opening).
• Problems with the chimney (insufficient air circulation).
• Poor position of ceramic parts (e.g. coals, logs, or matrix).
NOTE: Batteries do not tolerate high ambient temperatures, eventually this may cause leaking which could
damage the valve, meaning a new valve required (not covered under any warranty). Typically the maximum
ambient temperature for alkaline batteries is 50°C.
Indicates there is an issue with the thermocouple connection to the valve, or that there is an incorrect
reading from the thermocouple.
Possible reasons:-
• No thermocouple connected.
• Thermocouple connection reversed/incorrect.
• Insulated thermocouple wire shorting to chassis earth (damaged insulation).
• Damaged, defective, or worn out thermocouple.
Indicates a flame is detected on pilot after valve has shutdown.
Possible reasons:-
• Carbon or other conductive contamination on spark electrode.
• Combustible material burning on pilot near electrode (carbon deposits etc.).
• If EASYTEST box used – simulate flame mode not operated correctly.
