Product Information: The fan is the component that pushes fresh air in to the combustion chamber, allowing the gas to be burnt correctly. It also clears the burnt gas after the combustion process is complete. The boiler has safety parameters in place to make sure no gas can be passed through to the main burner if the fan is not functional.
This part is present in 4 different boilers in the Vaillant range including the Vaillant ECOmax PRO (2003-2010), ECOmax PRO (2003-2010), VU 186-O , VU 286-O .
