The Daikin-McQuay 300043670 Flame Sensor is an essential accessory of HVAC systems and a safety part mainly applied to gas furnaces, boilers, and water heaters. Its main use is to sense the existence of a flame during the burning cycle. When gas valve opens, the flame sensor creates a little electric current that indicates whether there is a flame. It also protects users from dangerous conditions such as leaking of gas or even explosion since when the flame is put off, the sensor immediately stops the flow of the gas. Some benefits of this flame sensor include Energy efficiency.
