Where does the fuel piping run from and to?

The correct answer is that the fuel piping runs from the outlet of the point of delivery to appliance shut off valves. This definition accurately reflects the role and routing of fuel piping in a gas distribution system. The point of delivery is where the gas enters a building, typically at the meter, and the piping then directs the gas to various appliances through shut-off valves.

Understanding this path is critical for ensuring safety and compliance with plumbing codes. It highlights the importance of being aware of where gas is delivered after it enters the building and how it is distributed to individual appliances. Properly routed piping is essential for efficient operation and for meeting safety standards, such as ensuring that each appliance has a dedicated shut-off valve for maintenance and emergency situations.

The other options do not provide a complete or accurate description of the fuel piping system's routing. For instance, while gas appliances are connected to the fuel piping, the focus should be on the delivery point to the shut-off valves specifically.
