The Thermal Safety Switch detects the increased heat generated by the flue gas spillage and deactivates the furnace or boiler
Designed for use on residential and light commercial millivolt or 24 VAC gas furnaces, boilers and water heaters
Product Description Our thermal safety switches efficiently detect flue gas spillage due to a blocked flue, continuous down drafting or inadequate draft condition. With the safety switch wired in series with the burner circuit, the switch will de-energize the system's burner or burner control once it senses the spillage of hot flue gases. Available for gas-fired and oil-fired applications.
