@tomkatgastraining: 🔥 HOW TO TEST A THERMOELECTRIC DEVICE ON A MULTIFUNCTIONAL GAS CONTROL 🔥 In this video, I demonstrate how to test the thermoelectric safety device incorporated within a multifunctional gas control. You may come across this type of control on older appliances, including back boilers and some flueless appliances. This type of control can cause confusion, particularly among engineers who have been told to carry out what is sometimes called a “mini tightness test.” I explain how to test the device correctly using a digital manometer and confirm that the safety valve has closed and no gas is passing. Have you come across many of these multifunctional gas controls? Let me know below 👇 #GasTraining #GasEngineers #BoilerSafety #ThermoelectricDevice #TomKatGasTraining
