G2 Gas Fitter Practice Exam

Conducting a pilot turndown test is essential because it ensures safety and reliable ignition of the appliance. This test assesses the ability of the pilot light to remain lit under reduced gas flow conditions. A properly functioning pilot light is crucial for the safe operation of gas appliances, as it ignites the main burner when required. If the pilot light cannot stay lit at lower settings, it may lead to gas accumulation and increase the risk of hazardous situations, such as explosions or carbon monoxide poisoning. Performing this test helps verify that the pilot is stable and will operate effectively across various conditions, enhancing both safety and reliability in gas appliances.
