What kind of gas systems do the gas code primarily focus on?

The gas code primarily focuses on natural gas and propane systems because these are the fuels most commonly used in residential, commercial, and industrial applications for heating, cooking, and powering appliances. The code sets forth safety standards and installation guidelines to ensure that systems function properly and reduce the risk of hazards such as leaks, fires, and explosions.

Natural gas and propane systems have specific characteristics and handling techniques that distinguish them from other types of systems, such as electric or hydraulic systems. The code covers aspects such as proper venting, pressure regulation, and appliance connections, all of which are critical to ensuring the safe use of these gases. By concentrating on natural gas and propane systems, the code aims to provide a comprehensive framework for safe operations in environments where these fuels are used.
