What is the spark gap required for a spark ignitor?

The spark gap required for a spark ignitor is typically between 1/8 to 3/16 inches. This range is important because it allows the ignitor to produce a sufficient spark for ignition while ensuring reliability and safety in operation. A proper spark gap facilitates the optimal functioning of the ignitor, ensuring that it can consistently create a spark that's powerful enough to ignite the gas being used in appliances, like furnaces or water heaters.

Choosing this specific gap distance helps accommodate variations in gas pressure, the type of gas, and environmental conditions, which can all affect ignition performance. Maintaining this recommended range promotes effective ignition while minimizing the risk of malfunction or incomplete combustion, which could lead to safety hazards. Thus, the specified 1/8 to 3/16 inch gap is tailor-made to assure safe and effective operation of spark ignitors.
