Therefore, gas appliances can use low-pressure circuits, which eliminates the risk of electric shock, and directly detects the presence or absence of current flowing to the ventilation fan, so it can prevent abnormalities such as power outages, forgetting to turn on the ventilation fan, or disconnection of the fan coil. The gas supply can also be cut off at any time.
