Firomatic® Thermal Switches are temperature actuated safety devices installed in the electrical control circuit of a power burner. This provides additional protection as a control inter-lock. Provided with a thermal link set at 165˚F these devices are normally positioned at the ceiling, above the burner, or where code(s) require. Firomatic Thermal Switches use the same handwheel / fuselink as used with our manual valves. A 200˚F handwheel / fuselink may be substituted for the standard 165˚F for higher temperature applications. Please check AHJ for code compliance before using the higher temperature fuselink.
Firomatic Thermal Switches SHOULD NOT be used to manually start or stop the burner. When properly installed, there are no exposed electrical contacts or wires.
