What kind of fuel is used in a ventless gel fireplace?

A ventless gel fireplace uses a specially formulated gel fuel as its primary source of energy. This gel fuel is designed to burn cleanly and efficiently, producing a beautiful flame that resembles a real wood-burning fire without the need for a chimney or venting system. The gel fuel is typically made from isopropyl alcohol, which is a clean-burning fuel that doesn't emit any smoke, soot, or harmful emissions. It is also important to note that the gel fuel used in ventless gel fireplaces is specifically manufactured for this purpose and should not be substituted with other types of fuel, such as gasoline or ethanol, as they can be unsafe and may damage the appliance.
