The Riello RL70 diesel burner fires light oil in boilers and heaters.
See the main Riello RL70 oil burner page for details.
What is a riello rl70 diesel burner?
An oil burner mixes atomised fuel with air and burns it in a boiler or heater. A pump pressurises the diesel, the nozzle sprays it as a fine mist, electrodes ignite it, and a photocell or flame sensor proves the flame. A control box runs the start-up and shuts the burner down safely on a fault.
Burner output must match the boiler. Therefore, choose the model by boiler rating, fuel and the combustion chamber, and follow the maker data.
