The SCHWANK JS-0577-YY is a blocked flue switch engineered as a critical safety component for SCHWANK radiant heating systems. Designed to detect restricted or obstructed flue conditions, this switch interrupts heater operation before dangerous exhaust backpressure or combustion byproduct buildup can occur — protecting both equipment and occupants.

Key Features
  • Rated operating pressure of 0.90″ W.C. (water column) for precise flue blockage detection
  • Direct OEM replacement part for compatible SCHWANK radiant heaters
  • Provides automatic safety shutdown upon detection of blocked or restricted flue conditions
  • Helps maintain safe and efficient combustion by monitoring flue integrity
  • Durable construction built to withstand the demands of commercial and industrial heating environments
Application

The JS-0577-YY is a genuine SCHWANK OEM replacement blocked flue switch, intended for use with SCHWANK infrared and radiant tube heaters. It serves as a pressure-actuated safety device that monitors flue gas exhaust flow. When flue pressure exceeds the 0.90″ W.C. threshold — indicating a blockage — the switch trips to shut down the heater, preventing hazardous operating conditions.
