Brivis Error Code 54 Rollout Lockout: During a heat cycle, a flame rollout signal is detected with the maximum rollout events allowed exceeded.
For Heater Repair Tech Only
Reason: This error indicates the unit has locked out, due to 3 consecutive flame roll outs detected, within a heating cycle. Service Check List: 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.
