Reznor 195292 Flame Sensor

An essential safety shut-off component for Reznor gas-fired unit heaters is the Reznor 195292 Flame Sensor. This 4.25-inch-long sensor is housed inside the burner assembly and is composed of sturdy materials. It uses a voltage signal—230V in this case—to identify the existence of a flame. The flame of a properly functioning burner breaks the electrical route in the sensor. The control board of the unit heater receives this signal and guarantees that the system operates safely moving forward. The interrupted voltage signal causes a safety shut off in the event that the flame burns out or malfunctions, stopping the unit heater and stopping gas flow into the burner. The Reznor 195292 Flame Sensor protects against potential gas leaks and risks like carbon monoxide poisoning by guaranteeing the presence of a flame.
