Why is it important to identify the correct gas type before installation?

Identifying the correct gas type before installation is crucial because different types of gases, such as natural gas, propane, and butane, possess distinct properties, including varying pressures and combustion characteristics. Each type of gas has its own specific requirements for safe handling, appropriate equipment, and efficient operation. For instance, natural gas typically operates at lower pressures compared to propane, which can have higher pressure requirements. Additionally, the combustion characteristics influence how the gas burns, the efficiency of the system, and the safety measures needed during installation and operation. Understanding these differences ensures that the correct appliances and equipment are selected, optimizing performance and safety.

The other options address important aspects of the installation process, such as compliance with local codes, proper fittings, and understanding the company involved; however, they do not capture the critical technical reasons related to the inherent properties of the gases themselves and the implications for safe and effective installation.
