Product Information: The fan is the device that injects fresh air in to the combustion chamber, allowing the gas to be burnt correctly. It also removes the noxious 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 functioning correctly.
This part is present in 3 different boilers in the Powermax range including the Powermax POWERMAX HE , POWERMAX HE , POWERMAX HE .
