What is the spark gap required for a spark ignitor?

1/4 to 3/8 in.
3/8 to 1/2 in.
1/16 to 3/16 in.
1/8 to 3/16 in.

The correct answer is: 1/8 to 3/16 in.

The spark gap required for a spark ignitor is specified to be within the range of 1/8 to 3/16 inches. This measurement is crucial for ensuring that the spark ignitor operates efficiently and safely. A gap that is too small may not create a sufficient spark to ignite the gas, while a gap that is too large could lead to an inadequate spark or complete failure to ignite. The reason this specific range is appropriate relates to the voltage produced by the ignitor. A gap of 1/8 to 3/16 inches allows for optimal electrical discharge, ensuring that the energy from the ignitor can effectively jump the gap and ignite the gas. Maintaining the correct gap is essential for reliable performance of gas appliances, enhancing safety during operation. Understanding this measurement helps gas fitters ensure proper installation and maintenance of ignition systems in various gas technologies.
