I have a wv-DV-04-130 boiler with a Riello burner. The nozzle is 1.1 x 60B . What is the actual firing rate? Why would the factory turbulator setting to 4.0. ? Shouldn’t it be 1.5 instead?

The firing rate for the PEERLESS WV-DV-04-130 boiler with a Riello burner and a 1.10 x 60° B nozzle is 1.25 GPH. This firing rate can only be achieved with a Riello F-3 burner.
The factory turbulator setting is 4.0 instead of 1.5 because this higher setting is required to properly mix air and fuel at the higher firing rate of 1.25 GPH, ensuring efficient combustion and performance with the Riello burner.
