RS · RL · RLS gas, light-oil and dual-fuel burners
What a Riello burner code actually names
Riello burners met on board are read by the fuel they fire before anything else, and the burner itself carries a type plate that has nothing to do with the boiler's own plate.
Fuel-type identification
In Riello's own designation key the R is followed by the fuel: S for natural gas, L for light oil, LS for light oil and gas, and N for heavy oil. RS, RL and RLS are therefore the gas, light-oil and dual-fuel programmes, and the letters decide the parts before the size does. The burner carries its own type plate, separate from the boiler, so both readings are needed to open an enquiry correctly.
Wear and control items
A burner request is usually a group of small items rather than one: nozzles, electrodes, the flame detector, the ignition transformer, the oil pump, the solenoid valve, the fan and the control box. List them against the burner type, and note the fuel actually in use, since that decides the nozzle and the pump.
Reading a Riello burner plate
Riello S.p.A., founded in 1922 and headquartered in Legnago, near Verona, Italy, built its first light-oil burner in 1923, joined UTC Climate, Controls & Security in 2016 and now operates under the direction and coordination of Ariston Holding N.V. It supplies gas, oil and dual-fuel burners to the makers of boilers, generators and ovens, so on board a Riello burner is a bought-in unit fitted to a boiler built by someone else. The full type code from the burner's own plate — not the boiler's — is what identifies the specific machine and its spare-parts range.
A boiler enquiry and a burner enquiry are not the same request
The burner and the boiler it fires are built by different makers and carry different plates, and treating them as one identification step is where a Riello enquiry most often stalls.
A Riello burner is fitted to the boiler as a bought-in unit, and it is read by fuel type before size: RS for gas, RL for light oil, RLS for dual fuel. The letters decide the parts range before the frame size does, so a request built around the boiler's own plate alone leaves the burner itself unidentified — the burner's type plate is a separate reading and has to be sent in addition to, not instead of, the boiler's.
Once the burner type is confirmed, the wear-and-control items travel as a group rather than one at a time: nozzles, electrodes, the flame detector, the ignition transformer, the oil pump, the solenoid valve, the fan and the control box. Which of these are affected by fuel type is worth stating up front — the nozzle and the pump follow the fuel actually fired, not the burner series alone. For the solenoid valve in that group, the solenoid valve coil reader reads the voltage, duty and plug form from its coil. The fan in that group blows air drawn from the room, and where the ventilation of the engine room is in question, the engine room ventilation calculator counts the combustion air of the boilers with that of the engines.
What a Riello line resolves to
Grouped as a burner strip-down actually divides, because a fuel-type question and a wear-item question are not the same line.
- Nozzles, matched to the fuel actually fired
- Electrodes and the flame detector
- Ignition transformer
- Oil pump, on light-oil and dual-fuel burners
- Solenoid valve
- Fan and control box
- Complete overhaul kits by burner type and fuel
A burner strip-down is answered as a group, not one item at a time — the burner type and the fuel actually fired settle the nozzle, the pump and the rest of the list together.
Plate data that makes a Riello enquiry quotable
The burner's own plate is the fastest route to a correct match. With the items below an enquiry can usually be priced in one pass; without them it comes back with a clarifying question first.
- Full burner model from the burner's own plate, every letter included — fuel letters and size, the regulation suffix (/M mechanical cam, /E electronic cam), TC (standard head) or TL (long head) — plus the burner's code number, which Riello's manuals list against each model
- Fuel actually fired — gas, light oil or dual fuel
- Which wear or control items are needed
- The boiler's own make and model, sent alongside the burner plate
- Photograph of the burner plate and of the part being requested
- Vessel and IMO number, the port and the ETA
- Whether the part requested is one a survey asks about — the ignition transformer, the flame detector or the control box — and the certificate requirement that applies to it
A control box and a nozzle are not answered alike
Requests naming Riello burner components arrive mixed, and the review differs by what the line actually touches.
The ignition transformer, the flame detector and the control box are the items a survey is most likely to ask about, since they govern how the burner starts and shuts down safely, and these go to an OEM-route review by default.
Nozzles, electrodes, gaskets and other size-and-material consumables are ordinary supply questions, and a verified alternative can be reviewed on them where a buyer's approval requirements allow, with dimensional and material documentation checked at RFQ stage. Vessel Core is an independent spare parts supplier and marks the proposed route against each line on the list, so a mixed request naming both kinds of item is answered by line, not as one blanket route.
Riello burner parts — questions from the engine room
Which Riello burner series come up most often in spare-parts requests?
RS is the gas programme, RL the light-oil one and RLS the dual-fuel one, and the letters decide the parts before the size does. Send the burner's own type plate reading, separate from the boiler's.
Why does the burner have its own plate separate from the boiler?
A Riello burner is a bought-in unit fitted to the boiler, not part of the boiler's own build, so it carries its own type plate and its own parts range. Quoting from the boiler's plate alone leaves the burner unidentified; both readings are needed.
What parts are ordered together on a Riello burner request?
A burner request is usually a group of small items rather than one: nozzles, electrodes, the flame detector, the ignition transformer, the oil pump, the solenoid valve, the fan and the control box. List them against the burner type and state the fuel actually in use, since that decides the nozzle and the pump.
What should a Riello burner spare-parts RFQ contain?
A workable request lists the full burner type from its own plate, the fuel actually fired (gas, light oil or dual fuel), and which items are needed from the nozzle, electrode, transformer, pump, solenoid valve, fan and control box group. A photograph of the burner plate settles most of the remaining questions in one pass.
Is Vessel Core connected to Riello?
No, and there is no agreement of any kind. Vessel Core holds no dealership, distribution, representation or partnership agreement with Riello, and quoting a component against the RS, RL and RLS designations implies no approval by the maker and no claim of interchangeability.
Submit your RFQ now.
Send your Riello burner request — burner type (RS, RL or RLS), the fuel actually in use, and the specific items needed: nozzle, electrode, flame detector, ignition transformer, oil pump, solenoid valve, fan or control box. A photograph of the burner's own type plate, separate from the boiler's, is what confirms it.
