Performing a natural gas regulator adjustment is essential for maintaining system stability, safety, and performance—especially when using a monitor and control configuration. In this step-by-step video, our warehouse manager, Jack, demonstrates how to adjust gas regulator set points on a USG Model 243 regulator. You’ll learn exactly how to ensure the monitor and control units function without conflict.
Whether you're doing a new install or routine maintenance, this guide walks through how to adjust a natural gas regulator using proper sequencing and pressure calibration techniques. Avoid regulator overlap and ensure accurate system pressure with this trusted method.
Watch the video below to learn how to properly adjust, monitor, and control regulators for optimal gas pressure management.
Key Takeaways from the Video
- Always begin your natural gas regulator adjustment by backing off the monitor to its minimum setting.
- Adjust the control regulator first—this unit should manage day-to-day system pressure.
- Set the monitor regulator slightly higher so it only activates if the control fails.
- Use a manometer under flowing conditions (not static) to verify pressure accuracy.
- Maintain enough pressure spread between regulators to prevent overlap or competition.
- This method applies to the USG 243 and other DOT-compliant gas regulator configurations.
Why Set Point Adjustment Matters
Knowing how to adjust a gas regulator properly ensures that the monitor and control units each serve their purpose. Without a correct spread between the regulators, the system can suffer from pressure instability, inefficient performance, or even safety hazards.
Proper natural gas regulator adjustment ensures smooth operation and reliable over-pressure protection—critical in maintaining infrastructure integrity and user safety.
