All our products work with an alcohol based fire gel or liquid Bio FUEL that is smoke and fume free. 

The fuel is poured directly into the container provided and can be filled to the top if desired.

To light, simply touch the surface of the fuel with a naked flame. A long lighter is most suitable for this but matches can also be used.

Do not leave any dead matches inside the container as this causes smoke. Once lit, the flame will slowly grow to its full height and then burn consistently.

To extinguish the fire replace the lid. On certain models the flame can be regulated by closing the lid adjust the flame height.

Allow the container a little time to cool before refilling. (10 mins is usually enough)

Wash out the container every three to four burnings to prevent residue build up. 

The length of time the gel lasts is dependant upon the size of the actual reservoir.
Typically one bottle of gel will provide up to 5 hrs burn time in a medium gel fire, a little less for the larger burners.

Bio fire burn times are in product description

Gel fires and bio fires can be used both indoors and outdoors.
