The Heatline fan is the component that pushes fresh air into the combustion chamber, allowing the gas to be burned correctly. It also extracts 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 operational.
