When using the longest length method for sizing gas piping, measurements are taken from what point?

• A. The gas meter
• B. The point of delivery to the most remote outlet
• C. The appliance location
• D. The main supply line

Answer: (B)

The longest length method for sizing gas piping involves measuring from the point of delivery to the most remote outlet. This approach ensures that the gas pressure is adequate at the furthest appliance or outlet, which is crucial for safe and efficient operation. By starting from the point of delivery and measuring to the most remote outlet, you can determine the total length of piping that the gas must travel, taking into account all turns, fittings, and other factors that could impact pressure along the way. This method is particularly important because it helps to account for potential pressure drops that might occur due to friction and resistance as the gas moves through the piping system. Consideration of the gas meter, appliance location, and main supply line alone would not provide a complete picture for proper sizing. The focus on the most remote outlet ensures that the system is designed to function effectively for all appliances served, not just the nearest ones.
