The Firomatic 12527 thermal switch is essential for maintaining safety in fuel burner installations. This device is thermally activated and is installed in the electrical power line of the burner. It is set to deactivate the burner when surrounding temperatures reach one hundred sixty-five degrees Fahrenheit. This quick action helps prevent overheating. The unit is typically installed near the ceiling, close to the burner for optimal function. It is important to note that this switch should not be used to manually control the burner.
When installed correctly, the Firomatic thermal switch enhances safety by ensuring there are no exposed wires before or after use. After activation, the fusible element, which acts as the manual control, requires only a simple replacement of the hand wheel to restore functionality.
