Description
The Reznor 201159 Pressure Switch is a genuine OEM safety control designed for commercial and industrial Reznor gas-fired unit heaters. This pressure switch is calibrated to 1.40″ water column (W.C.) and uses a single-pole single-throw (SPST) contact to monitor draft and combustion airflow. It verifies that adequate negative pressure is present in the venting system before allowing the burner to ignite and continue operation, helping prevent unsafe conditions caused by blocked vents, failed ventor motors, or insufficient draft.
