Biomass ethanol alcohol fuel can be safely burned indoors and outdoors, but there are some important things to remember when using alcohol fireplaces:
Never burn biomass ethanol alcohol fuel unattended.
Place the free-standing alcohol fireplace horizontally, similar to a solid floor or a flat outdoor floor to prevent it from tipping over.
Be extra careful when using alcohol fuel outdoors; do not use it in strong winds or rain or snow.
Each time you add alcohol, only place the fuel container in the proper place in the body of the alcohol fireplace.
