IMPORTANT: Installation must be performed by a qualified professional in accordance with all local codes and regulations.
- Gas Supply Shut-off: Before beginning any work, ensure the main gas supply to the appliance is completely shut off.
- Location: Install the regulator in an upright position, ensuring the arrow on the regulator body points in the direction of gas flow towards the appliance.
- Connections: Connect the inlet side (3/8 NPT) to the gas supply line and the outlet side (3/8 NPT) to the appliance's gas inlet. Use appropriate pipe sealant on all threaded connections.
- Leak Test: After installation, slowly turn on the main gas supply. Apply a non-corrosive leak detection solution to all connections. Bubbles indicate a leak. If a leak is detected, immediately shut off the gas supply, tighten connections, and re-test.
- Ventilation: Ensure adequate ventilation around the regulator.

The Sourcefy GR-130 Natural Gas Regulator is designed for automatic operation. Once properly installed and the gas supply is turned on, it will automatically reduce and maintain the gas pressure to the specified outlet pressure (5" W.C.) for the connected appliance.
- No user adjustment is typically required for standard operation as the outlet pressure is factory set.
- Ensure the appliance connected to the regulator is compatible with the specified outlet pressure.
