Flue
The following instructions have the purpose of
giving instructions on installation of a good flue,
however they do not replace in any way the
standards in force of which a qualified builder must
be aware. The thermostove manufacturer cannot
be held in any way liable in civil or criminal terms for
poor operation of the thermostove due to a wrongly
sized flue and/or non-compliance with legislation in
force, which must be complied with. The flue must
be built to standard and category ≥ T200 or higher,
with a vertical progression without choking, resistant
to condensate and resistant to fire caused by soot. It
must be externally insulated to avoid smoke cooling
and it must have a condensate drain. If the flue is a
cement shaft, it must be ducted. The flue must be
inspected for cleaning and must also be distanced
from flammable and/or combustible materials. The
opening area for smoke evacuation must be at least
double the section of the flue and must prevent
snow and animals from entering. The measurement
of the opening in the atmosphere must be outside
the backflow zone caused by the shape of the roof
and/or any obstacles found nearby. Pay attention to
the presence of skylights and dormer windows.
Installation of the flue is not permitted shared with other equipment.
Chimney
The opening area for smoke evacuation must be at
least double the section of the flue and must prevent
snow and animals entering. The measurement of
the opening in the atmosphere must be outside the
backflow zone caused by the shape of the roof and/
or any obstacles found nearby. Pay attention to the
presence of skylights and dormer windows.

The minimum distances to comply with from any
chimneys or reflux zones are outlined below.
Check the negative pressure between the flue
and the environment installed comply with the
instructions in the technical characteristics. The
minimum height of the flue is 3.5 metres and must
have an internal section that allows compliance
with these requirements and however not over
100mm. Check the correct configurations using
UNI EN 13384-1.
The flue must always be clean. Any soot residue
reduces the section of the flue which would
compromise draught and the soot could catch
fire. Have a professional chimney sweep clean
the flue and the chimney at least once a year and
before switching on the generator after periods of
inactivity. Lack of cleaning will negatively impact
correct operation of the equipment.
