What is the maximum length of semirigid metallic tubing used to connect a gas appliance?

• A. 4 feet
• B. 6 feet
• C. 8 feet
• D. 10 feet

Answer: (B)

The maximum length of semirigid metallic tubing used to connect a gas appliance is 6 feet. This specification is in place to ensure safety and efficiency in gas delivery systems. The tubing must be kept to this length to minimize the potential for gas leaks and to maintain adequate pressure for appliance operation. This limitation helps to avoid excessive bending or tension that can occur in longer tubing, which may lead to damage or failure of the connections. Understanding this maximum length is crucial for proper installation and compliance with safety codes in gas appliance connections.
