According to NFPA 54, what must be done to ensure the safe operation of gas appliances?

To ensure the safe operation of gas appliances, regular maintenance and inspection are essential. This process allows for the identification and correction of potential issues that could lead to unsafe conditions. For example, during routine maintenance, technicians check for leaks, analyze the performance of safety devices, and ensure that all components are functioning as they should. Regular inspections help maintain efficiency and safety standards required by regulations, such as those outlined in NFPA 54.

Maintenance practices might include cleaning burners, inspecting vent systems, checking gas connections, and ensuring that combustion air is not obstructed. These actions not only enhance the operational efficiency of appliances but are critical for minimizing risks such as carbon monoxide buildup and potential gas leaks, ensuring that the appliances operate safely within their design parameters.

The other options, while potentially important in different contexts, do not address the fundamental need for regular upkeep that directly impacts the safe operation of gas appliances.
