Description
The Reznor 209973 Flame Sensor designed to provide flame detection for safe and efficient operation of the HVAC systems. It checks the burner flame to ensure that it has ignited properly. The sensor produces a microcurrent when it is exposed to a flame, and the control board can confirm combustion. It is often used in Reznor gas-fired unit heaters and helps to improve the performance of the equipment and minimize the time when it does not operate. Advantages include enhanced safety, better heating efficiency, and prevention of fuel accumulation for the system’s longevity and less frequent maintenance.
