The new exclusive patented Paramount fuel is the perfect fuel source for your Paramount garden burner. Rated for both indoor and outdoor use, each can emits up to 3000 BTUs of heat and burns for an average of 2-3 hours each. Paramount Smartflame is made from a patented formula that uses a special wick to burn. If the fuel spills out of the can the spilled material will not continue to burn, giving the consumer peace of mind. Smartflame offers a thick quality flame just like regular ethanol gel fuel. One can lasts 2.5 to 3 hours, and produces approx. 3000 BTUs per can, just like regular gel fuel. There is no odor and it is easily extinguished by placing the lid or a snuffer over the opening.
