What is defined as "direct ignition" in flame effect systems?

Direct ignition in flame effect systems refers to the capability of an ignition system to ignite fuel without the use of a pilot flame. This means that the system can initiate combustion either through an automatic or a manual process and does so by introducing an ignition source directly to the fuel mixture. The absence of a pilot flame distinguishes direct ignition from other methods that rely on a continuously burning flame to ignite additional fuel, thus simplifying the ignition process and potentially providing a quicker response to ignition requirements.

This understanding aligns well with flame effect design and safety protocols outlined in the NFPA 160 standard, which emphasizes the importance of ensuring that all ignition methods are reliable and reduce the risk of unintentional ignition. Knowing that direct ignition systems are designed to efficiently ignite fuel directly contributes to their significance in safe flame effect performance.
