Safety Switches

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.
