The GAS P/M series covers a firing range from 130 to 4885 kW.

Operation is featured by progressive two stage operation or full modulation, with an advanced modulating control system and probes.

The burners of GAS P/M series are well suited for applications requiring versatility of control (process, steam, refrigerating absorption) where a variable output is needed.

Due to their metal sheet structures, they are specifically suitable for process applications where plastic materials could be easily damaged or deformed.

Simplified maintenance is achieved by sliding bars which permit the access to the combustion head without need of removing the burner from the boiler.

A RIELLO burner (Heat Generator), where it is matched with a water-based boiler (Heater Housing) with a nominal output ≤ 400 kW, providing heat for heating purposes and heat to deliver sanitary hot water, can be installed:

- With boilers (heater housings) already in service in the field, for replacement, in conformity to Article 1, paragraph 2, point (G) of the EU Regulation No. 813/2013;

- With boilers (heater housings) on a new installation, if they have emissions complying with the requirement of Annex II, paragraph 4 of the EU regulation No. 813/2013.
