- ZEN AIRTIGHT
Sealed installation means that the product is certified as sealed and its installation (ducting
of the combustion air and connection to the chimney) is airtight with respect to the installa-
tion environment.
A sealed installation does not consume the room’s oxygen but draws all the air from the outer environment (if suitably ducted) and
makes it possible to install the product, therefore, it can be installed in all houses that require a high degree of insulation such as
“passive” or “high energy efficiency” houses. Thanks to this technology there is no risk of smoke emissions in the room, hence no
air inlets and relevant ventilation grilles are required in the installation premises.
Consequently, there will be no more draughts of cold air in the room, which would otherwise make it less comfortable and reduce
the overall efficiency of the system. The sealed stove may even be installed in a sealed installation that is compatible with the
presence of forced ventilation or in premises that might have negative pressure with respect to the outside.

MINIMUM DISTANCES
Observe the distances from flammable objects (sofas, furniture, wood panelling, etc..) as specified in the following diagram.
If objects considered to be particularly sensitive to heat are present, such as furniture, curtains or sofas, as a precaution, increase
the stove clearances substantially to avoid possible deterioration due to the effect of heat.

If the floor is made of combustible material, use a protection made of non-combustible material (steel, glass...) that also protects
the front from any falling combusted material during cleaning operations.
Always fit a floor guard if the floor is made of flammable material.
