The Navien Tankless Water Heaters 30010455A is an Ignition Transformer NCB/NCB-E, for Navien’s NCB and NCB-E. It is a small electrical device that is relevant to ignition. It controls the power supply to the water heater and passes low-voltage electricity 120V or 240V AC to the transformer according to the model. By efficiently using silicon steel and ferrite this low voltage is transformed into a high voltage spark. The high voltage is switched towards the igniter electrode to fire the internal gas burner of the water heater and begin with the heating phase. The advantage is that it guarantees a constant high-voltage spark.
