SMARTFUEL pure bio-ethanol fuel for ventless fireplaces is your best choice for both indoor and outdoor use. It is the cleanest burning smokeless fireplace fuel on earth. SMARTFUEL was created especially for indoor ventless fireplaces and is completely ‘Planet-Friendly’. It is a clean, sustainable bio-ethanol fuel specially formulated to provide the most beautiful fire possible while complying with all regulations required by U.S. Government agencies. The only by-products created when burning SMARTFUEL fuel are water vapor and very small amounts of carbon dioxide, similar to human breath. No toxins or offensive fumes are emitted while it burns – the flame is clean and odorless. SMARTFUEL burns efficiently and there is no oily residue left in the tank to clean up as with other bio-ethanol fuels which contain petroleum distillates. SMARTFUEL is the ONLY fuel on the market with exclusive SAFETY-POUR technology – which provides the safest possible flash-free transfer of fuel from the bottle to the fireplace tank. SMARTFUEL burns with an interesting dancing yellow flame with orange and blue accents and lasts longer than any other alcohol fuel on the market. It has the lively look and warmth of a real wood fire, without any soot… or guilt from burning a fuel made from food. For child safety, “BITR” is added as a human aversive. It’s overwhelming bitter taste helps prevent accidental ingestion by children and small animals. No soot, no smoke, no smell, and no residue. It’s totally sustainable, and your ‘Greenest Ethanol Choice’.
