An annual service should include checking and replacing the nozzle, cleaning the photocell and electrodes, inspecting the combustion head, checking pump pressure, replacing the oil filter, and performing a combustion analysis.

What oil pump pressure should a Riello burner be set to?

Riello light oil burners are typically set to 12 bar (approximately 174 PSI). The standard setting can be varied by +2 bar depending on specific requirements.

Why must there be no owner-serviceable parts inside a Riello burner?

Riello burners contain high-voltage ignition components (over 10,000 volts at the electrodes), pressurised fuel systems, and precision-calibrated parts. For safety reasons, there are no owner-serviceable parts inside the burner cover. All maintenance beyond external cleaning must be carried out by an OFTEC registered heating technician for oil burners or a Gas Safe registered engineer for gas appliances.

How often should the blast tube be cleaned on a Riello burner?

The blast tube should be regularly cleaned using a stiff brush, compressed air, or a neutral cleaner to remove debris. This is typically done every 1,000-2,000 operating hours or during annual servicing.

How can I improve the efficiency of my Riello heating system?

Regular annual servicing keeps the boiler running efficiently. Lagging central heating pipes reduces heat loss, bleeding radiators removes air pockets that reduce efficiency, and ensuring correct pump and boiler settings optimises performance.
