The international company Ferroli has been designing, developing and manufacturing high-quality equipment for systems of heating and air conditioning for premises of different purposes. The equipment Ferroli is distinguished by reliability, safety and economy. The operation of the equipment facilitates is eased by Ferroli boiler troubleshooting system, which is shown below in a chart form.


PROBLEMCAUSE/SOLUTIONS
After a few attempts at ignition, the electronic controller shuts down the boiler.Pilot light nozzle dirty Clean with compressed air.
Check the regular gas flow to the boiler and the air has been eliminated from the pipes.
Check that the electrodes are correctly positioned and free of any deposits.
Make sure that the boiler is connected to a good earth connection.
Check the connections to the ignition and ionization electrodes.
The electrodes are not discharging in the ignition phase.Check that the electrodes are correctly positioned and free of any deposits. Regulation thermostat adjusted too low.
Check the electrical power supply.
Check the connections to the ignition and ionization electrodes.
Check the connections at the electronic flame controller.
Make sure that PHASE and NEUTRAL are not inverted and that the earth contacts are efficient. Check the inlet gas pressure and any open pressure switches.
Reset the safety thermostat.
Reset the fume thermostat.
Make sure the room thermostat is closed.
The burner burns poorly: flames too high, too low or too yellow.Gas valve filter dirty.
Check the gas supply pressure.
Gas nozzles dirty.
Make sure that the boiler is not dirty.
Make sure that ventilation in the room where the unit is located is sufficient for good combustion.
Smell of unburnt gas.Make sure that the boiler is clean.
Check the draught of the flue.
Check that gas consumption is not excessive.
The boiler works but the temperature fails to increase.Check the 2-stage adjustment thermostat works properly.
Check that the operator of the 2nd stage of the gas valve (full power) is supplied. Check that gas consumption is not less than that provided for.
Make sure that the boiler is perfectly clean.
Check that the boiler is adequate for the system.
Check that the heating pump is not blocked.
Temperature of the water to the system too high or too low.Check the 2-stage adjustment thermostat works properly.
Check that the pump is not blocked.
Make sure that the characteristics of the circulating pump are adequate for the system.
Burner explosion. Delay on ignition.Check that the gas pressure is sufficient and the boiler casing is not dirty.
The adjustment thermostat switches back on with too great a temperature difference.Check that the thermostat bulb is properly inserted in the sheath.
Check the 2-stage thermostat works properly.
The boiler produces condensation water.Check that the boiler is not operating at too low a temperature (below 50°C).
Check that gas consumption is regular.
Check the efficiency of the flue.
The boiler goes out for no apparent reason.Fume thermostat trips.
Safety thermostat trips due to temperature rise.
