Description
The SCHWANK JS-0577-XY is a genuine OEM blocked flue switch engineered for use with SCHWANK radiant heating systems. Designed to monitor flue pressure and shut down the burner in the event of a blocked or restricted flue condition, this safety switch helps protect equipment, property, and occupants from the hazards associated with improper venting.
Product Overview
This pressure-actuated safety switch is factory-set to trip at a setpoint of 1.20″ W.C. (inches water column), providing precise and reliable detection of abnormal flue backpressure. When the monitored pressure exceeds the rated setpoint — indicating a potential flue obstruction — the switch interrupts the burner control circuit, preventing unsafe operation until the condition is resolved and the system is manually inspected and reset.
