The Heatline adaptor part is located around the fan section. The fan is the component that injects fresh air into the combustion chamber, allowing the gas to be burned correctly. It also extracts 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 operating correctly.
Fits multiple appliances
