Tjernlund Products 950-0476 Fan Prover Kit
The Tjernlund Products 950-0476 Fan Prover Kit is a critical safety component designed for commercial PAI series intake hoods and draft inducer systems. This kit functions as a differential pressure-sensing mechanism that confirms the mechanical draft is established before allowing the heating or ventilation equipment to fire. Engineered for high-reliability applications, the 950-0476 fan prover monitors real-time airflow to prevent hazardous conditions caused by restricted venting or mechanical failure. As a veteran-grade HVAC replacement part, this assembly integrates seamlessly with the Tjernlund UC1 Universal Control and other interlock circuits. The kit includes the sensing switch, flexible pressure tubing, and necessary mounting hardware to ensure a precise pressure switch calibration. By verifying that the inducer is moving air at the required velocity, this kit safeguards the heat exchanger from thermal stress and ensures total compliance with modern venting safety codes in both residential and commercial mechanical systems.
Key Benefits- Ensures consistent HVAC system safety by preventing operation during airflow failure.
- Direct OEM replacement part for Tjernlund PAI-series commercial intake hoods.
- Includes high-temperature flexible tubing to withstand demanding mechanical room environments.
- Provides a normally open (NO) contact that closes only upon successful fan operation detection.
- Simplifies the ventilation monitoring process for contractors through a straightforward two-wire integration.
How do you troubleshoot a Tjernlund fan prover switch that won't make?
First, inspect the PAI-series prefilter and intake hood for debris. If the filter is clear, check the sensing tubing for kinks or cracks. Use a manometer to verify that the draft inducer is producing sufficient pressure to satisfy the fan prover kit settings.
Is this kit compatible with other draft inducer brands?
While designed specifically for Tjernlund PAI and commercial venting systems, the 950-0476 functions on standard differential pressure logic. Always verify the specific pressure trip point (WC) against your system requirements before installation.
What wiring configuration is required for the 950-0476?
Typically, the blue lead is connected to Common and the yellow lead to the Normally Open (NO) terminal. This ensures the circuit only completes once proper mechanical draft is achieved.
