* It must be ensured that the structure in the building has the appropriate dimensions
for the installation of the intended equipment;
* There should be a gap of around 0,19 inches (5 mm) between the unit and
ornamental stones, to allow room for the metal to expand. These should also be
installed so as to allow the unit to be removed without causing damage, if the need
arises; This recommendation does not apply to the Back Box Eco and Back Box Slim
Eco.
* If the chimney is made of brick, it should not be too wide as the smoke spreads and
cools it, thus affecting the extraction. If it is difficult to draw a smoke, the chimney
can be fitted with a turntable or a metal tube inside the chimney to improve the
draught;
* Ensure that the opening in the wall is of an appropriate size to house the unit.
* Materials/objects placed in front of the unit, as well as behind in the case of the Box
range, should be able to withstand the heat radiated from the glass of the door(s), so
should not be combustible.
* Refractory cement or other refractory material should be applied on the chimney
walls.
* The use of wood finishings may increase the risk of fire. Therefore, we recommend
the use of adequate insulation or that would not be used at all.
