When the stove surface temperature rises its maximum working temperature, the safety device gently elevates the front of the fan to protect the center module and motor.Automatic workingNo batteries or electricity required, the stove fan operates automatically when the surface temp of the stove reaches 158-230 degrees Fahrenheit (depending on the type of fireplace). And the only moving part is the blade accessory, which makes the wood stove fan almost totally silent even at top speed.Notice:Please allow 1-3cm error due to manual measurement and make sure you do not mind before ordering.Please understand that colors may exist chromatic aberration as the different placement of pictures. *Please make
