Description
The Viessmann 7858519 Ignitor/Flame Sensor Assembly is a two-purpose ignition and sensing that is applied in HVAC systems. It produces the first spark or heat needed to start the burner and then senses the existence of flame when it is in operation. The assembly which is installed in the combustion chamber of boilers or furnaces, is used to make sure that the fuel is only provided when the right conditions of ignition and flame are met. It operates in the system with the control module to achieve secure start-up, flame confirmation.
