✓ Installation Tips

Always shut off the gas supply at the main shutoff valve before disconnecting or installing any gas connector. Commercial gas hoses must be installed by a licensed gas technician in most jurisdictions — verify local codes before proceeding. Do not reuse old gas connectors; replace with a new certified hose at every appliance move or reinstallation. Hand-tighten fittings first, then use a wrench for a snug final fit — do not over-tighten. After installation, apply an approved gas leak detection solution to all connections and inspect for bubbles before restoring gas supply. Ensure the hose is not kinked, pinched, or in contact with sharp edges after installation.
