The fireplace fan is placed on the mantel and uses the temperature and heat of the mantel to generate electricity to power the fan. The fan's rotation speed varies depending on the combustion temperature inside the mantel shelf; the higher the stove temperature, the faster the fan speed. When the stove temperature is low enough for the fire to go out, the fireplace fan slows down until it stops rotating. Normal operating temperature: 50°C to 350°C.Package List:1 x Chimney FanNote:Do not use the chimney fan if the oven temperature exceeds 345°F.
