Reznor 197029 Pressure Switch
The Reznor 197029 Pressure Switch is a critical OEM replacement part engineered for combustion airflow safety in Reznor UDAP and UDAS series gas-fired unit heaters. This differential sensing switch features a 0.6" water column (WC) set point, indicated by its distinct blue label. Designed specifically for high-altitude applications and precision draft monitoring, it ensures the inducer motor establishes a consistent vacuum before allowing the ignition sequence to proceed. It serves as a direct upgrade for the legacy part number 173312, providing high-reliability switching in demanding commercial and industrial environments.
Integrated into the safety circuit, the 197029 monitors for blocked vents or inadequate draft conditions to prevent hazardous operation. This unit is commonly utilized in UDAP60, UDAP75, UDAS60, and UDAS75 heaters, particularly those equipped with the factory-installed common vent (Type CV) option. For the Reznor UBZ60, this switch functions as the primary pressure control for altitudes ranging from sea level up to 6,000 feet. The assembly includes a pre-mounted bracket for efficient field installation and secure positioning within the heater cabinet.
Key Benefits for Technicians:- Precise Airflow Detection: Factory-calibrated at .60" WC to ensure accurate verification of the induced draft before the gas valve opens.
- Broad Compatibility: Direct-fit replacement pressure switch for popular UDAP, UDAS, and UDXC-30 units, minimizing field diagnostic time.
- High-Altitude Optimized: Engineered to maintain stable switching thresholds in varying atmospheric conditions.
- Rugged OEM Construction: Durable diaphragm design built to withstand recurring thermal cycles and industrial vibration.
- Which Reznor models use the 197029 switch? It is standard for UDAP30, UDAS30, UDAS45, UDAS60, and UDAS75 models, and serves as the high-altitude pressure switch for select UBZ units.
- How do I identify this switch in the field? Look for the blue label and the ".60" set point printed on the housing.
- What does a flashing light on the control board indicate regarding this part? Typically, a constant blink on the LED suggests the pressure switch is stuck open or failed to close during the inducer run-up.
