During post-installation checks for a flame effect system, what is the main safety objective of performing a leak test?

• A. To validate flame color
• B. To adjust ignition timing
• C. To verify there are no gas leaks and to ensure safe operation
• D. To confirm the control software version

Answer: (C)

Leak testing is a safety check whose goal is to confirm there are no gas leaks in the system so it can operate without risking fire, explosion, or toxic exposure. Practically, you inspect all joints, fittings, hoses, and regulators with a leak-detection method (soap solution or electronic detector) and repair any leaks found until the test shows no leaks. Only after a successful leak test should you move on to commissioning steps like ignition checks or flame appearance; other options focus on performance or software rather than safety.
