The Halstead fan assembly is the device that injects fresh air into the combustion chamber, allowing the gas to be burned correctly. After the combustion process is over, it also eliminates the gas that was burned. If the fan isn't working, the boiler is equipped with safety measures to ensure that no gas may be transferred to the main burner.
Voltage is 230 V
