4. Insert installation manual
4.1. Fire protection
The fireplace should be installed on a smooth and even
surface after checking its load capacity, taking into account
both the weight of the insert, as well as its housing. It is
recommended to make a foundation for the fireplace that is
min. 50 mm thick.
After mounting, the insert should be levelled with
adjustable feet.
The floor around the fireplace must be made of non-
combustible material, keeping the distances given
below:
non-flammable
material
flammable items
Fig.1
Installation of the fireplace insert must be a self-
supporting structure, without any direct connection to
the insert It should provide easy access to the insert
and its connections for servicing and inspection
purposes. The housing of the insert should be insulated in
such a way that its vertical and slanting surfaces do not heat
up over 120°C, and the horizontal surface (shelves on which
objects can be placed) - over 85°C.

* H - absolute height from the ground
to the bottom of the fireplace
The walls around the fireplace should be protected from
heat by using insulation made of non-combustible
materials.
The ceiling above the fireplace should be protected by
making a decompression chamber from insulating
materials. The minimum distances to be kept for the
foundation and installation of the Unico fireplace insert are
shown in Figure 1 and Table 1.

Do not place any objects made of flammable materials on
an insert without housing. It is absolutely necessary to
keep the appropriate distance of flammable objects from
the fireplace:
•
min. 200 cm from the edge of the firebox in the
radiation area
•
min. 5 cm from the edge of the insert housing outside
the radiation area
4.2. Ventilation
The minimum cubic volume of the room in which the
fireplace insert will be installed should result from the

indicator of 4 m
/l kW of the nominal power of the insert,
but should not be less than 30 m
conditions of the insert, proper ventilation of the room in
which it will be installed should be provided. The necessary
amount of ventilation air is 10 m
insert power. If other heating devices are installed in the
room with the fireplace, ventilation should be provided so
that the amount of air for all devices is sufficient and that
they do not interfere with each other.
