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 systems burner or burner control once it senses the spillage of hot flue gases. Available for gas-fired and oil-fired applications.
Thermal safety switch detects the increased heat generated by the flue gas spillage and deactivates the furnace or boiler|It will not allow the burner to restart until the switch has been manually reset|Gold contact material|Normally closed switch: opens at 180 deg F and manual reset close|Thermal safety switch are used when on barometric draft controls and draft hoods to detect flue gas spillage and deactivate oil and gas burners
