tHe fLUe:
Further to the general prescriptions, the flue must
• only be used to discharge smoke
• be correctly sized to satisfy the requirements of
smoke discharge (EN 13384-1)
• must preferably be insulated, in steel with a circular
internal section. If rectangular, the corners must
have a radius of not less than 20 mm, with a ratio
of the internal dimensions of <1.5
• must normally be at least 1.5 metres in vertical
length
• must have a constant cross section
• must be waterproof and thermally insulated to
ensure a good draw
• must preferable have a collection chamber for
non-combusted matter and condensation.
• if pre-existing, it must be cleaned to prevent any
fire hazard
• in general, we recommend fitting a tube inside the
existing masonry chimney if its diameter is greater
than 150 mm. This recommendation is purely for
guidance; the installer must assess wile installing,
after the calculation of the draw.
IntUbAteD systeM:
Further to the general prescriptions, the intubated
system must:
• operate in negative pressure
• be open to inspection
• be compliant with local regulations.
tHe cHIMney Pot must:
• be wind-proof
• have an internal cross section equivalent to that of
the flue and a smoke outlet at least double that of
the interior of the flue
• extend beyond the back flow zone (in Italy, refer to
UNI 10683 point 6.5.8.)
• allow for maintenance of the chimney
For dual flues (which should be spaced at least 2 m
apart), the chimney pot receiving the smoke from the
solid fuel appliance or that from the higher storey, must
be at least 50 cm higher than the other

AIR IntAKe foR coMbUstIon
In general, we suggest two ways to ensure a proper
flow of combustion air. Air must come from the outside*
It is also important to ensure a change of heating air
and glass cleaning air etc.
Indirect air intake
The boiler stove takes air from the outside through the
hole on the rear.
Install an air outlet at floor level with an effective sur-
face area (net of the mesh or other protections) of at
least 80 cm
2
To prevent draughts, we recommend installing the
intake behind the product or behind a radiator.
Installing it in front of the appliance will create
unpleasant draughts.
Direct air intake**
Install an air intake of effective area (net of the mesh or
other protective equipment) at least equal to that of the
air intake at the back of the product.
Connect the air intake to the appliance's air intake with
a tube (which may also be of the hose type). Increase
the diameter of the pipe if it is not smooth: assess its
pressure drops.
We recommend not exceeding a length of 3 m,
considering the draw of the flue. For each curve, up
to a maximum of two, the length must be reduced by
1 m. You should also consider increasing the diameter
of the pipe.
*The air may be drawn from an adjacent room only if:
• the flow is taken from permanent and unobstructed
openings communicating with the outdoors
• the air pressure in the adjacent room is never
lower than that of the outdoor pressure
• the adjacent room is not a garage. subject to fire
hazard, a bathroom or bedroom
• the adjacent room is not a shared room in the
condominium
In Italy, UNI 10683 provides that ventilation is sufficient
even if a pressure difference between the outdoors
and indoors of no more than 4 PA is guaranteed (UNI
EN 13384-1). The installer who issues the declaration
of conformity is responsible for ensuring these
conditions.
**The direct connection of the air intake does not
make the product airtight. It is therefore necessary also
to ensure recovery of the air taken in the room by the
product (i.e. for the glass cleaning)
