What is the first step you should take before lighting any appliance pilot?

• A. Do a walk through of the piping system
• B. Check the gas meter reading
• C. Open the appliance valve slowly
• D. Verify the regulator inlet pressure

Answer: (A)

Before lighting any appliance pilot, you must verify the gas path is sound by doing a walk-through of the piping system. This safety step checks for leaks, damaged joints, or loose connections that could allow gas to escape and ignite when the pilot is lit. Identifying and addressing these issues first prevents a dangerous ignition from occurring. After confirming the piping is intact, you proceed with the remaining steps—checking for gas supply, ensuring valves are set correctly, and then lighting the pilot. The other actions describe follow-up checks or operations that rely on a safe, leak-free system, so they aren’t the first step.
