   • Confirm that the gas is off by testing a nearby gas appliance.

2. Install the Gas Piping:

   • Cutting the Pipes: Use a pipe cutter to cut the pipes to the required lengths. Avoid using a saw, as it can create burrs that can cause leaks.
   • Threading the Pipes: If using black iron pipes, thread the ends of the pipes using a pipe threading tool.
   • Applying Pipe Joint Compound: Apply pipe joint compound (pipe dope) to the threads of the pipes and fittings. Ensure the compound is specifically designed for gas lines.
   • Connecting the Pipes and Fittings: Tighten the pipes and fittings using two pipe wrenches. Ensure the connections are snug but not over-tightened, as this can damage the threads.
   • Supporting the Pipes: Support the gas lines with pipe hangers or straps every few feet to prevent sagging and strain on the connections.

3. Install Valves and Regulators:

   • Install shut-off valves at key points in the system, such as near each appliance and at the main gas supply line.
   • Install a gas pressure regulator to maintain a consistent gas pressure to your appliances. Ensure the regulator is properly sized for your system's demand.

4. Connect Appliances:

   • Connect the gas lines to the appliances using flexible gas connectors or rigid pipes.
   • Ensure the connections are properly tightened and sealed.
   • Use a gas leak detector to check for leaks at each connection.

5. Pressure Testing:

   • After completing the installation, pressure test the gas lines to ensure there are no leaks.
   • Connect a pressure gauge to the gas line and pressurize the system with air or nitrogen to the pressure specified by local codes.
   • Monitor the pressure gauge for any drop in pressure. If the pressure drops, there is a leak that needs to be located and repaired.
   • Use a gas leak detector or a soap bubble solution to locate the leak.
