What is the maximum outlet pressure of second stage regulators?

The maximum outlet pressure of second-stage regulators is 14 inches of water column. This measurement is crucial as it represents the maximum pressure that should be delivered to the appliances from the second-stage regulator, ensuring safe operation. Proper outlet pressure is vital for efficient combustion and appliance performance.

Regulators are designed to reduce high-pressure gas from the first stage to a more manageable level for use by appliances. Second-stage regulators specifically handle the outlet pressure, and a maximum of 14 inches of water column is standard to maintain safety and functionality. Setting the pressure too high might result in excess flow that could affect appliance operation negatively, while too low may provide insufficient gas for proper combustion, impacting performance and efficiency.

Understanding these pressure specifications helps prevent accidents and ensures that appliances are operating within their designed parameters.
