Reznor 201160 Pressure Switch

The Reznor 201160 Pressure Switch is a critical safety and performance component designed for Reznor high altitude kits and heaters operating above 6,000 feet. This OEM replacement pressure switch ensures a precise air-to-fuel ratio by monitoring the venter motor pressure, maintaining a specific 1.05" W.C. setpoint. Identified by its distinct brown label, this SPST switch is a standard requirement for contractors upgrading or servicing Reznor UDX, UDZ, UBX, and UBZ series unit heaters in elevated regions. Without a correctly calibrated high altitude induction switch, units may face nuisance tripping or improper combustion due to thinner air density.

Built for industrial durability, the Reznor 201160 is compatible with 200, 225, 250, 300, 350, and 400 MBH models. This 1.05" WC pressure switch effectively prevents the heater from firing if the venting system is obstructed or if the inducer fan fails to reach the required static pressure. When installing this HVAC pressure switch, seasoned technicians should verify the tubing continuity and secure the electrical leads to the 1/4" quick-connect terminals to ensure a reliable combustion air proving circuit.

• OEM Precision: Genuine Reznor 201160 part ensures exact calibration for high altitude HVAC applications.
• Specific Setpoint: Pre-set at 1.05 inches water column for accurate combustion air proving.
• Broad Compatibility: Engineered for Reznor UDXC, UBX, and UDZ unit heaters ranging from 200 to 400 MBH.
• Color-Coded Identification: Features a brown label to prevent cross-installation with standard altitude switches.
• Reliable Operation: Robust SPST switch logic designed to withstand the rigorous cycles of commercial unit heaters.

When is a Reznor 201160 pressure switch required?
This switch is typically required for Reznor heaters installed at elevations exceeding 6,000 feet (1,830 meters) to compensate for decreased air density and ensure proper pressure switch activation.

Will this switch work for a Reznor UDX100?
No, the 201160 is specifically sized for larger units (200-400 MBH). For smaller models like the UDX100, you will typically need the 197032 switch or a model-specific high altitude kit.

Why does my Reznor 201160 have a brown label?
Reznor uses color-coded labels—in this case, brown—to quickly identify the 1.05" W.C. rating, helping technicians distinguish it from standard altitude or different pressure switches during field service.
