Burnham 104604-01 Differential Pressure Switch WC - 1.17

The Burnham 104604-01 is a differential pressure switch designed specifically for residential and commercial boiler applications. This safety device monitors the pressure differential across the system to ensure proper combustion air flow and safe operation.

Key Features:

• Fixed set point at 1.17 inches water column (WC) for consistent, reliable operation
• Monitors induced draft blower performance to ensure adequate combustion airflow
• Automatically deactivates boiler operation when airflow is insufficient
• Restores boiler operation when proper combustion air is detected
• Direct replacement for OEM part number 80160761
• Factory-calibrated for accurate pressure differential monitoring

Application:

This pressure switch is compatible with Burnham PVG and SCG Series 3 & 4 boilers. It serves as a critical safety component that prevents burner operation when the induced draft blower fails to move sufficient combustion air, protecting the system from dangerous operating conditions.

Installation Note:

This is a genuine Burnham replacement part designed for direct fitment on compatible boiler models. The fixed set point eliminates the need for field adjustment, ensuring proper safety parameters are maintained.
