Description
The Reznor 197029 Pressure Switch is a genuine OEM airflow safety control designed for commercial and industrial Reznor gas-fired unit heaters. This pressure-activated switch monitors the vent and combustion airflow to ensure proper draft conditions before and during burner operation. When the measured differential reaches the calibrated 0.60″ water column, the switch confirms safe airflow and allows the combustion sequence to proceed — helping protect the system and maintain reliable operation.
