The primary purpose of sizing gas piping systems is to ensure efficient gas delivery. Properly sized gas pipes are crucial because they directly impact the flow rate and pressure of the gas being delivered to appliances. If the pipes are too small, they can restrict the flow, leading to insufficient gas supply and potential operational issues for appliances. Conversely, if the pipes are oversized, it can cause a decrease in pressure, again affecting performance. Regulations are designed to ensure that gas delivery systems are sized appropriately to facilitate optimal performance, safety, and efficiency in the operation of gas appliances. This focus on efficiency is paramount in preventing problems like incomplete combustion, safety hazards, and increased operational costs. Thus, the correct answer emphasizes the importance of maintaining an efficient gas delivery system, which is aligned with regulatory standards for safety and performance.
