Brivis Error Code 44 Roll out: During an ignition a flame rollout signal is detected and the maximum rollout events allowed has not been exceeded.
For Heater Repair Tech Only
Reason: During ignition a flame roll out has occurred where the flame has earthed the antiflame roll out (AFRO) bar to the burner assembly. This error display will only be seen on the display while the heater is currently recovering from conditions of flame sensed on the AFRO bar indicating a flame roll out. This is the 10 second shut down period of the gas valve, before the next re-ignition attempt. Service Check List: • Operate the heater and observe the behaviour during ignition. Determine which AFRO is causing the roll-out. Rollout on lower AFRO • 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. • Check that the vacuum pressure switch is the correct switch and functioning correctly. • Check for water gurgle noises being emitted from either the flue or the heat exchanger inlet ports (Water gurgle can be the result of premature condensation or a blocked condensate drain system on SP 6 models) • Check if the flue terminal or flue pipe has soot marks, indicating poor combustion and/or a possible blocked heat exchanger. Rollout on Upper AFRO • Check the burners for blockage. • Check the burners for correct fitment.
