How should gas tubing be altered or extended?

1. By using any available length

2. Utilizing flexible connectors only

3. Following manufacturer's guidelines

4. By a licensed professional only

The correct answer is: Following manufacturer's guidelines

The correct choice emphasizes the importance of adhering to manufacturer’s guidelines when altering or extending gas tubing. This requirement is crucial because the manufacturer's specifications are designed to ensure safety, efficiency, and compliance with applicable codes and standards. These guidelines are based on extensive testing and regulatory requirements aimed at preventing gas leaks, ensuring proper installation, and maintaining the integrity of the system. When gas tubing is altered or extended without following these guidelines, it can lead to hazardous situations, such as leaks or even explosions. Each type of gas system and tubing may have specific instructions regarding the materials, connections, and installation techniques to be used. By following the manufacturer's instructions, homeowners, inspectors, and contractors can ensure that the gas system is safe and functions properly. In contrast, the other options imply a more flexible approach that does not prioritize safety or established standards. Using any available length may not consider the specifications required for effective and safe gas transportation. Relying solely on flexible connectors may not provide a secure and reliable installation unless specifically recommended by the manufacturer. Moreover, while having work performed by a licensed professional is important, they should also be following the manufacturer's guidelines to ensure the job is done correctly and safely.
