Tjernlund Products 950-1031 Fan Prover
The Tjernlund Products 950-1031 Fan Prover is a critical safety component designed for side wall power venters. This pressure switch kit serves as a fundamental interlock, ensuring that the ventilation system has established sufficient airflow before the burner is allowed to fire. By monitoring the static pressure differential, the 950-1031 prevents the operation of high-efficiency heating appliances under hazardous "no-flow" conditions, protecting the equipment and the structure from flue gas backup.
This comprehensive kit includes a metal sensing tube and a specialized mounting bracket, calibrated to a 0.40" WC fixed set point. It is engineered for seamless integration with Tjernlund HS2, HST-2, HSUL-2, and HS115-2 models. As a technician-grade fan prover kit, it utilizes high-precision diaphragm technology to provide reliable electrical contact closure even in demanding mechanical room environments. Installing this original equipment manufacturer (OEM) part ensures the proper airflow and system safety required to meet rigorous building codes and manufacturer specifications.
Key Benefits:
- Precise Pressure Sensing: Calibrated to 0.40" Water Column (WC) to ensure the burner only activates when draft induction is fully established.
- Complete Installation Kit: Includes the sensing tube and mounting hardware required for a standard power venter retrofit or repair.
- Model Compatibility: Directly compatible with Tjernlund HS-series power venters, maintaining factory-spec performance.
- Enhanced Safety: Acts as a primary safety interlock to prevent the buildup of combustion byproducts in the event of fan failure.
- Industrial Durability: Rugged construction designed to withstand the thermal cycling and vibration found in commercial or residential HVAC ventilation.
Common Questions:
How do I verify if the 950-1031 is the correct switch for my venter?
This fan prover is specifically engineered for the Tjernlund HS2, HST-2, HSUL-2, and HS115-2 series. Verify your model number on the venter housing before installation.
What is the purpose of the sensing tube in this kit?
The sensing tube facilitates the pressure differential measurement between the venter's inlet and the atmosphere, allowing the internal diaphragm to trigger the fan prover electrical switch.
Can the pressure set point be adjusted in the field?
No, the 950-1031 features a factory-calibrated 0.40" WC set point to ensure consistent system safety and to prevent unauthorized tampering with airflow thresholds.
