Which of these must an appliance be to comply with regulations unless approved otherwise?

• A. Certified
• B. Listed
• C. Unlisted
• D. Non-approved

Answer: (B)

The correct answer, "listed," refers to the necessity for appliances to meet specific safety standards set by recognized testing organizations. An appliance that is listed indicates it has been tested and certified for safety and performance, ensuring that it complies with relevant regulations and codes. This compliance is critical for protecting both users and property from potential hazards associated with gas appliances. Appliances must typically be listed to ensure they adhere to federal and state regulations, which helps maintain consistent safety across different manufacturers and models. This means that unlisted appliances or those that are labeled as non-approved do not meet the necessary safety standards. A certified appliance might be considered alongside being listed, but certification typically refers to the process by which an appliance is evaluated, while listing specifically denotes inclusion in a recognized directory. Therefore, while certification is important, the fundamental requirement for regulatory compliance is that the appliance must be listed.
