Product Information: The fan is the device that pushes 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 working correctly.
This part is present in 3 different boilers in the Worcester range including the Worcester CBI 19/24 FON, CBI 19/24 FOP, CDI 24 .
