Gas Fitter Test 2025 – 400 Free Practice Questions to Pass the Exam

Gas-fueled appliances can operate using various types of gases, each with its own properties and uses. Natural gas, propane, and butane are all commonly utilized fuels in applications such as heating, cooking, and hot water.

Natural gas is most prevalent in residential settings, supplied through pipelines and known for its efficiency and lower greenhouse gas emissions when burned. Propane is often used in rural areas where natural gas pipelines are not available, and it is stored in tanks for use in various appliances. Butane, although less common, is used in portable stoves and lighters due to its ability to evaporate easily at atmospheric pressure.

Since all three gases are suitable for powering gas appliances, the answer that includes all of them recognizes the versatility and availability of each type of gas in different scenarios. Understanding the specific applications and suitability of each gas type is crucial for anyone involved in gas fitting and appliance operation.
