    Brivis Fault Code 47

    Brivis Error Code 47 Unstable Flame: During Flame Validation, the flame signal is lost within the flame validate time and the maximum attempts at flame validation have not been exceeded.

    For Heater Repair Tech Only

    Reason: A flame has been detected by the flame sensor within the flame detect time of 4.5 seconds, and then the flame has been lost in the flame validate time (10 seconds after flame detection). If this failure occurs 5 consecutive times after an ignition attempt, then an Error 55 is registered and a lockout condition will occur. Once flame has been validated and ignition is successful, the failure count is reset. Service Check List: • Operate the heater and observe the behaviour during ignition, in particular the behaviour of the flame at the burner near the flame sensor. • During ignition, measure the ignition burner pressure and ensure it is within specification. Check that the correct injectors have been fitted and the gas type is correct. Too much gas flow during ignition can cause violent flame behaviour. • Check that the vacuum pressure switch is the correct switch and functioning correctly. • Check that the inlet gas pressure is sufficient during ignition (at least 800 Pa for ignition). • Check for continuity between the flame sensing rod and the lead connector. • Check the flame sensor rod is located in the correct location as specified in Section 4.4. • Clean the flame sensor rod and retry ignition.
