Description
The Reznor 204325 Pressure Switch is a genuine OEM safety control component engineered for commercial and industrial Reznor gas‑fired unit heaters. This pressure switch is calibrated to 0.8 in. water column (W.C.) and verifies that proper combustion airflow and draft conditions exist before allowing the burner to ignite and continue operation. By monitoring pressure changes during the induced draft sequence, this switch helps protect the heat exchanger and ensure safe, efficient combustion.
