Riello Burner information and Instruction.
Riello Burner information and Instruction.
In this Blog I will share some advice on general maintenance and how to keep your Riello burnerhappily running for as long as possible, as well as showing a faults, possible causes and solutions table. This will help should you choose the correct spare part should you need one.
Maintenance frequency. The combustion system should be checked at least once a year by a representative of the manufacturer or another specialised technician. They can advise on spares required is necessary.
Combustion. The optimum calibration of you Riello burner requires an analysis of the flue gases. Significant differences with respect to the previous measurements indicate the points where more care should be exercised during maintenance.
Pump. The delivery pressure must be stable. Unusual noise must not be evident during pump operation. If the pressure is found to be unstable or if the pump runs noisily, the flexible hose must be detached from the line filter and the fuel must be sucked from a tank located near the Riello burner. This measure permits the cause of the anomaly to be traced to either the suction piping or the pump. If the pump is found to be responsible, check to make sure that the filter is not dirty. The vacuum meter is installed upstream from the filter and consequently will not indicate whether the filter is clogged or not. Contrarily, if the problem lies in the suction line, check to make sure that the filter is clean and that air is not entering the piping.
Flexible hoses. Checks to make sure that the flexible hoses are still in good condition and that they are not crushed or otherwise deformed. Check periodically the flexible pipes conditions.
Fuel tank. Approximately every 5 years, or whenever necessary, suck any
Water or other impurities present on the bottom of the tank using a separate pump.
Filters.Check the following filter boxes: on fuel supply line; in the pump, and clean or replace as required. If rust or other impurities are observed inside the pump, use a separate pump to lift any water and other impurities that may have deposited on the bottom of the tank. Then clean the insides of the
Pump and the cover sealing surface.
Nozzles. Do not clean the nozzle openings; do not even open them. Replace the nozzles every year or whenever necessary. Combustion must be checked after the nozzles have been changed
Combustion head. Check to make sure that all the parts of the combustion head are in good condition, positioned correctly, free of all impurities, and that no deformation has been caused by operation at high temperatures
Fan. Check to make sure that no dust has accumulated inside the fan or on its blades, as this condition will cause a reduction in the air flow rate and provoke polluting combustion.
Boiler. Clean the boiler as indicated in its accompanying instructions in order to maintain all the original combustion characteristics intact, especially the flue gas temperature and combustion chamber pressure. Leave the Riello burner working without interruptions for 10 min. and set rightly all the components stated in this manual.
Faults / Solutions Here below you can find some causes and the possible solutions for some problems that could cause a failure to start or a bad working of the burner. A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box. When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if the burner functions correctly, the lock-out can be attributed to a temporary fault. If however the lock out continues the cause must be determined and the solution found.
