FLUE
• Before positioning the stove, make sure the fl ue is suitable
for the smoke produced.
• When installing the stove, the position of the fl ue must
be taken into account in order to prevent incorrect smoke
duct paths; the size of the fl ue must comply with the specifi ca-
tions indicated in the technical data.
We recommend using insulated circular section fl ues made of
stainless steel with smooth internal walls.
The fl ue cross-section should be constant for its whole
length (we recommend a minimum height of 3.5 - 4 m).
• We recommend fi tting a chamber at the base of the fl ue
to collect solid material and any condensate. Dilapidated
fl ues and fl ues made of unsuitable materials (asbestos,
galvanized steel, corrugated iron, etc.) with rough or
porous internal surfaces are illegal and detrimental to
stove operation.
• The fl ue should be used for one single stove only (it
cannot receive the outlet of other fi reboxes)
• For a good draught, the fl ue should be free from
obstructions, such as bottlenecks, horizontal sections and
sharp edges; any nonvertical sections should slope by not
more than 45° from the vertical (fi g. 3).
• If the fl ue to be used has previously been used for other
stoves or fi replaces, it must be carefully cleaned to prevent
faulty operation and avert the risk of unburnt deposits
on the internal fl ue walls catching fi re.
• In normal working conditions, the fl ue must be cleaned
at least once a year.
• For optimal operation, the fl ue draught must create a
pressure drop between 0.12 and 0.2 mbars. Lower values
may lead to unpleasant smoke emissions when loading
the stove and produce excessive soot deposits; higher
values would lead to excessively fast combustion and a
decrease in thermal effi ciency. To fall within the correct
values, refer to the UNI Standard 10683 table.
• If there are several fl ues on the roof, the others should
be at least 2 metres away and the stove chimney pot
should be at least 40 cm higher than the others.
Please refer to the chapter of the UNI 10683 regulation
regarding positioning of chimney pots.
• We recommend installing a fi re damper on the smoke
duct.
INSTALLATION
SMOKE DUCT
The smoke duct connects the smoke outlet to the fl ue inlet.
The smoke duct must be made with steel or ceramic rigid
pipes. Flexible metal pipes or fi bre-cement pipes are not
allowed. Horizontal and counterslope sections should be
avoided. Any cross-secion change should be made in corre-
spondence of the stove outlet and not at the fl ue inlet.
Angles greater than 45° are not allowed (see fi gures
1,2,3,4).
The connection between the smoke duct and the steel fl ue
should be sealed with high temperature resistant mastic.
• To control the fl ow of fl ue gas we recommend installing a
damper in the smoke duct.
CHIMNEY POT
The chimney pot must have a wind guard (for any clarifi cation,
please refer to your retailer), an internal section
equivalent to that of the fl ue, and smoke outlet cross-section
at least twice that of the internal fl ue cross-section.
For correct operation, please refer to UNI 10683.
