The Ideal 174418 Air Pressure Switch is a genuine safety-critical component designed to monitor airflow and ensure the fan and flue system are operating correctly within the boiler. By detecting sufficient air movement before ignition, this switch helps prevent unsafe combustion conditions and protects the boiler from operating when ventilation is inadequate.
