At what point must connectors connect to a masonry chimney flue above the lowest portion of the interior?

• A. 6 inches
• B. 10 inches
• C. 12 inches
• D. 15 inches

Answer: (C)

The requirement for connectors to connect to a masonry chimney flue above the lowest portion of the interior is set at a minimum of 12 inches. This regulation ensures that the connectors are positioned high enough to minimize the risk of combustion gases escaping into the building and promotes proper ventilation and draft effectiveness. The 12-inch height also helps prevent potential backflow of exhaust gases, which can be hazardous to occupants. In construction and gas installations, following these specific measurements is vital for safety and compliance with local building codes, which are designed to protect both property and health.
