The MI-PWRFAN is a heat powered fan designed to circulate the warm air created by a wood-stove operating with normal surface temperatures of between 65°C and 345°C. The optimal running temperature of the wood-stove MI-PWRFAN is the same as the recommended safe operating temperature for wood-stoves of between 205°C and 345°C. The MI-PWRFAN generates it`s own electricity – so no need for batteries or mains power.Increased Efficiency and Comfort: Warm air is circulated directly into the living area rather than having most of the stoves heat rise immediately to the ceiling, thereby increasing the heating efficiency of your stove. Improved warm air circulation results in greater comfort and less fuel consumption. Many people use the MI-PWRFAN to to help combat dry air. This can be done by positioning the fan behind a tray of water on top of the stove to boost the rate of evaporation.Fuel Saving: Estimated fuel savings when using an MI-PWRFAN of up to 14%.Easy Operation: The MI-PWRFAN starts automatically and adjusts its speed with the stove temperature. As the stove heats up, the MI-PWRFAN runs faster to move more warm air into the room. As the stove burns down and cools, the MI-PWRFAN automatically shuts off.INSTALLATION The stove fan should be placed adjacent and slightly behind the flue pipe. Never place the stove fan in front of the flue pipe or at the front of the stove. The stove fan requires the cooler air flow from behind the stove to generate its own thermoelectricity. The stove fan should only be used with free standing stoves and is not suitable for other types of fireplaces including inset stoves. The stove fan should only be used with the base placed on the stove and not hung by the handle. SAFETY This stove fan will get extremely hot during operation. Never touch any part of the fan during operation. Only use the handle to remove/reposition the fan during operation and even then a stove glove must be used. Make sure the stove fan is never placed on an unprotected surface until it has completely cooled down. Children should be supervised when the stove fan is in use.
