                Recommended Fuel:

                Ethanol fuel burns cleanly and does not produce the soot, smoke, or mess that is normally associated with a wood-burning fireplace. This ethanol fireplace fuel is made from 100% alcohol without the use of any oil at all. Ethanol is produced from renewable agriculture products, like barley, grains, sunflowers, corn, wheat, and potatoes, and manufactured in an earth-friendly process that does not harm the environment.
