G2 Gas Fitter Practice Exam

The component of a venting system that is specifically designed to conduct flue gases from an appliance to a chimney is known as a vent connector. This part is crucial for safely directing exhaust gases away from gas appliances, ensuring efficient operation and minimizing the risk of dangerous backdrafts.

The vent connector is typically a short, horizontal pipe that connects the appliance's flue outlet to a vertical chimney or vent stack. It is constructed to withstand high temperatures and is often designed to maintain proper airflow, facilitating optimal venting performance. The correct choice emphasizes the integral role of the vent connector in the overall system of venting gas appliances safely and effectively.

Other terms, while related, refer to different parts of the venting or chimney system. For example, a venting pipe generally refers to any pipe used in a venting system rather than specifically identifying the connection to a chimney. A flue collar is the component attached to the appliance that serves as the outlet for flue gases but does not conduct the gases to the chimney itself. Lastly, a chimney adapter is often used to transition between different sizes or types of pipes, but it does not specifically refer to the segment that directly conducts flue gases to the chimney.
