WARNING The floor on which the fireplace is placed must
have sufficient load-bearing capacity (for the weight of the
fireplace, see Table 5).
DANGER! The floor on which the fireplace is placed must
consist of non-flammable materials. This is because hot ash
and sparks can fall on the floor. This also goes for the walls
behind and adjacent to the fireplace and the ceiling.
CAREFUL The fireplace and the surround have different
expansion rates. if a platform is used, the fire must be
at least 4 mm clear of the platform in order to prevent
damage. Too little room causes undesirable material
tension.
