Biofuel fuel is a special fuel for bioethanol fireplaces. It burns with a natural flame without soot and odor, only burning carbon dioxide and water when burning. The spirit contained in the preparation is made from natural and therefore renewable sources. 1 liter of fuel is sufficient for at least 3 to 5 hours of burning, depending on the performance of the bio-fire. Especially suitable for indoor use. For ignition, we recommend using only the lighter supplied with the bio fireplace. Fuel is only fed into the burner after it has been cooled down, refueling is prohibited! Follow the manufacturer's instructions for filling and ignition. Smaller spaces are recommended to briefly ventilate.
