Burner Ignition Transformers

An Ignition transformer plays a crucial role in the combustion process by converting the required voltage to generate a powerful spark that ignites the air and fuel mixture. Typically, these transformers accept an electrical input of 110v, 230 volts or 415 volts. Through the use of a copper-wrapped iron coil with one or two different windings, this initial voltage is transformed into an even higher voltage. The resulting voltage, usually around 10,000 volts, is then discharged through the HT leads, producing a spark at the electrode and initiating the combustion process.

When determining which Ignition transformer is suitable for your specific needs, the composition of the windings inside the transformer becomes a vital factor. If you're uncertain about the appropriate transformer for your system, a convenient method is to provide us with an image of the specification plate located on the side of your existing transformer. By examining this image, our experts can accurately identify and recommend the most suitable replacement for you.

Ignition transformers can experience failures for various reasons, with moisture being the most common culprit. The operation of burners generates heat, but during periods of inactivity when the components cool down, the heat from the transformer can come into contact with colder surfaces, leading to the accumulation of condensation. Over time, this moisture build-up can result in the failure of the ignition transformer.

Additionally, transformers can fail when exposed to constant vibration, which can loosen internal connections and compromise their functionality. For oil-fired burners, contamination can also contribute to transformer failure. The presence of oil or other substances in the vicinity of the transformer can lead to electrical short circuits or corrosion, ultimately affecting its performance.

To ensure the longevity and reliability of your ignition transformer, it is essential to maintain a clean and dry environment, minimize exposure to excessive vibrations, and promptly address any signs of contamination. Regular inspections and maintenance can help identify potential issues early on, allowing for timely repairs or replacements to prevent disruptions to your system's ignition process.
