Riello RS Series (gas burners)

The Riello RS Series is a broad family of gas burners — combustion equipment for boilers and generators, not boilers — from 44 kW to 8,010 kW across mechanical, electronic and variable-speed modulating ranges, including low-NOx BLU and ultra-low-NOx ULX versions.

Gas burners. The captured Riello literature describes the RS ranges as gas burners for natural gas; range-specific LPG options are not reprinted in the captured text, so propane is not claimed here. A burner is not a boiler: it is the combustion equipment mounted on a boiler or generator.

About the RS Series (gas burners)

The RS Series is Riello's gas-burner family and one of the widest lines in the official catalogue. Riello's range pages describe the RS burners as designed for 'low or medium temperature hot water boilers, hot air or steam generators' — they are the combustion equipment installed on those appliances, not boilers themselves. The family spans one-stage, two-stage and modulating operation, with mechanical (M), electronic (E) and variable-speed (EV) versions, in low-NOx BLU and ultra-low-NOx ULX variants.

The 2025 Technical Sales Catalogue prints firing ranges for the principal current families: RS 25-35/M BLU and RS 25-35/E BLU from 44 to 480 kW; RS 45-55/M BLU and RS 45-55/E BLU from 90 to 680 kW; RS 68-200/M BLU, RS 68-200/E BLU and RS 68-200/EV BLU from 150 to 2,400 kW; RS 310-610/M BLU, /E BLU and /EV BLU from 400 to 6,250 kW; and RS 810/M BLU, /E BLU and /EV BLU from 1,200 to 8,010 kW. The ultra-low-NOx ULX ranges print 150-2,400 kW (RS 68-200), 370-6,000 kW (RS 310-610) and 970-8,100 kW (RS 810).

The catalogue also indexes larger families including RS 1000-1200 (M BLU, E BLU, EV BLU, plus C01 and FGR versions) and RS 1300-2000 (E BLU, EV BLU, C01 and FGR), which extend the line beyond 2,000 kW; those ranges are listed in the official index, while the detailed firing tables captured here cover the BLU and ULX families above. Riello positions the RS range for low or medium temperature hot water boilers, hot-air or steam generators.

Riello's official market selector lists Canada, but no per-product Canadian approval statement appears on the captured burner pages, so canadianStatus is unknown. Boilers.ca documents the RS Series as combustion equipment for identification and service routing only; no boiler performance is claimed.

Frequently asked questions

Is the Riello RS Series a boiler?

No. The RS Series is a family of gas burners that mount on boilers, hot-air generators or steam generators. Riello manufactures burners; Boilers.ca documents the family as combustion equipment, not as a boiler line.

What output range does the RS Series cover?

Per Riello's 2025 Technical Sales Catalogue, the BLU families run from 44-480 kW (RS 25-35) through 1,200-8,010 kW (RS 810/M BLU), with ULX ultra-low-NOx ranges from 150-2,400 kW up to 970-8,100 kW, and larger RS 1000-1200 and RS 1300-2000 families indexed beyond that.

What is the difference between BLU and ULX?

BLU is Riello's low-NOx gas-burner designation and ULX its ultra-low-NOx designation; the ULX range pages print tighter NOx performance and use digital burner-management controls. The right choice depends on the local air-quality rules and the boiler being fired.
