    Hi,
    I had a GEM 70/90 (Riello burner) installed in 2010. Last year the nozzle had to be replaced because the boiler stopped working. Now I'm having a problem with the photosensor sooting over causing the boiler to stop working again, its happened a few time in the last week. Anyone have similar isues? could it be the nozzle again or can it be fuel. Any suggestions appreciated.

    What oil are you using ? Kerosene or gas oil

    The sooting problem can be caused by blocked flue ways , faulty nozzle , incorrect oil pressure and air adjustment .

    You wont be able to set this yourself , you need an oil pressure gauge , a smoke tester pump and an analyser .

    boiler needs to be tuned but it could be nozzle or pump pressure or lack of air.check fan and flue also

    If sooting is occurring, the appliance is not combusting the fuel correctly, this can be any combination of issues, from fuel to air to the appliance.

    In most instances it is due to poor set up, hence why a technician will use pressure gauges to set the oil, smoke pumps to test for sooting and a n electronic flue gas analyser to fine tune the combustion to precise settings.

    Where sooting occurs, large amounts of carbon monoxide is produced, so be careful!
