What is the function of an interrupted ignition source?

Functions continuously with flame
Ceases after the ignition trial period
Only operates during periods of high demand
Ignites gas without flame

The correct answer is: Ceases after the ignition trial period

An interrupted ignition source is designed to ignite gas for a specific duration and then cease operation after it successfully ignites the gas. This means that it does not remain active continuously; instead, it engages during the ignition trial period, which is the time required for the ignition to occur. Once the gas has been lit, the ignition source stops working, allowing for the controlled operation of the gas appliance without the ignition component active all the time. This characteristic is important for safety and efficiency, as it minimizes the risks associated with having an active ignition source when it is not needed. The other options suggest continuous operation or unnecessary behavior of the ignition source, which does not align with the intended function of an interrupted ignition system.
