What type of gas system might use a riser?

A fuel gas system typically employs a riser because it is designed to transport gas from a lower level, such as a basement or utility area, to higher floors in a building where the appliances that utilize the gas are located. Risers are vertical piping components that facilitate the movement of gas upwards through a structure while maintaining safety and efficiency. In such systems, proper installation and adherence to codes governing gas systems are critical to ensuring safe gas delivery and preventing leaks.

While gravity-fed water systems rely on gravitational force to move water and do not require vertical piping installations in the same manner, a piping system for oil might utilize different infrastructure suited specifically for liquid transport. High-pressure water systems can involve risers as well, but they serve a fundamentally different purpose, often connected to water distribution needs rather than gas conveyance. The specific focus on gas delivery makes the fuel gas system the most appropriate context for the use of a riser.
