Safety
Guidelines provided by Envirofit must be followed when manipulating the stove to avoid burns and spill-overs. Furthermore, keep all flammable items away from the surrounding area of the stove, and do not enclose the area you are cooking within; proper ventilation is always required. Do not touch the body of the stove while in use.
Complementary Technical Systems
Using a pot skirt will increase the efficiency of the cookstove. A G3300 pot skirt is available on Evans Outdoor Store's website.
