e-NRG is a liquid fuel and is NOT the same as gel fuels.

Gel fuels have added thickening agents that can reduce the heat output and fuel efficiency. It can also leave a sticky residue on the burner, which will eventually affect safe operation. Gel fuels are used only on burners specifically designed to use them.

EcoSmart Fires are designed and manufactured to burn only e-NRG liquid ethanol. Other fuels, especially gels, are not recommended. In fact, the use of brands other than e-NRG voids the burner’s warranty.
