Product Information: The fan is the component that introduces fresh air in to the combustion chamber, allowing the gas to be burnt correctly. It also clears the toxic gas after the combustion process is complete. The boiler has safety protocols in place to make sure no gas can be passed through to the main burner if the fan is not operational.
This part is present in 10 different boilers in the Biasi range including the Biasi 20SE , PRISMA 28SE , 24S 24S , 28S , PRISMA 24SER .
