3 STOVE SAFETY
3.1 Safety distance from flammable materials
To prevent the risk of fire, stove positioning must respect a minimum distance from flammable materials, according
to that given in the technical table of the manual and on the dataplate.
Pay attention to the type of floor: for delicate and flammable materials it is advisable to use plates in steel or
toughened glass as a support base (see section 2 - Transport and Installation). In case of particularly fragile objects
such as furniture, curtains or sofas, increase the stove distance considerably.
