What is the maximum outlet pressure for a second stage regulator on a residential propane tank system?

In a residential propane system, the second stage regulator is critical for maintaining a safe and usable pressure for appliances. The maximum outlet pressure of a second stage regulator is typically set to 11 inches of water column (W.C.). This pressure is suitable for most residential appliances designed to operate on propane, ensuring they receive an appropriate amount of gas to function efficiently without risking damage or safety issues.

Setting the outlet pressure at this level allows for adequate gas flow while keeping the system within safe operating limits. This is essential for appliances, as pressures that are too high can lead to malfunctions or unsafe conditions, while pressures that are too low can prevent appliances from lighting or operating correctly. Understanding the appropriate pressure levels is crucial for gas technicians to ensure proper installation and maintenance of propane systems in residential settings.
