What must all appliances and equipment undergo after the piping system is placed in operation?

• A. Calibration
• B. Testing for leaks
• C. Purging
• D. Installation of safety features

Answer: (C)

After a gas piping system is placed in operation, it is essential for all appliances and equipment to undergo purging to ensure safety and efficiency. Purging involves removing air from the gas lines before the gas is introduced, which prevents the formation of a combustible mixture that could lead to explosions or malfunctions when the appliances are ignited. This process helps to ensure that any residual air in the system is effectively eliminated, thus facilitating proper operation of the gas appliances and ensuring that they can operate on the intended gas supply without issues. Performing this essential step reduces risks and is in accordance with safety regulations outlined in the National Fuel Gas Code, ensuring both the safety of the installation and the performance of the appliances.
