ANTHEA – VENERE
The following features are FORBIDDEN and therefore
they endanger the good operation of the device:
asbestos cement, galvanized steel, rough and porous
internal surfaces. Picture 4 gives some examples of
execution.
The minimum section must be 4 dm
x 20 cm) for devices whose duct diameter is
lower than 200 mm or 6.25 dm
cm) for devices with diameter greater than 200
mm.
The draught created by the flue must be sufficient, but not
excessive.
A too big flue section can feature a too big volume to be
heated and consequently cause difficulties in the
operation of the device; to avoid this, tube the flue along
its whole height. A too small section causes a decrease of
the draught.
The flue must be properly spaced from any
flammable materials or fuels through a proper
insulation or an air cavity.
It is forbidden to let plant piping or air feeding channels
pass in the same flue. Moreover, it is forbidden to create
movable or fixed openings on the same for the
connection of further other devices.
6. CONNECTION TO THE CHIMNEY
For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading
of the fuel or for removing the ashes, while during the operation and
remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open door
is allowed under supervision. The connection pipe to the flue must be the shortest possible, right, tight and
according to the current regulations.
The connection to the chimney must be performed with stable and strong pipes (we recommend a thickness of
2 mm). The pipe for smokes exhaust must be fixed hermetically to the chimney. The diameter inside the
connection pipe must correspond to the external diameter of the smokes exhaust small trunk of the stove. This
is ensured by pipes according to DIN 1298.
ATTENTION: Eventual flammable pieces in the area of 20 cm round the connection pipes must be changed
with fireproof and not sensitive to heat materials.
For a good operation of the equipment it is essential that in the installation place it is introduced sufficient air
for combustion (see CHAPT. 10).
The depression on the chimney should be 12 - 14 Pa (=1.2-1.4 mm of water column). The measurement must
be done always with the equipment hot (rating calorific value). When the depression exceeds 17 PA (1.7mm of
water column) it is necessary to reduce the same with the installation of an additional flue adjuster (butterfly
valve) on the exhaust pipe or in the chimney.
For safety reasons the door of the stove must be opened only for the loading of the fuel or for removing the
ashes, while during the operation and
6.1. CHIMNEY CAP POSITION
The draught of the flue depends also on the suitability of the chimney cap.
Therefore, if it is handicraft constructed, the output section must be more than twice as big as the internal
section of the flue.
Should it be necessary to exceed the ridge of the roof, the chimney cap must assure the discharge also in
case of windy weather (Picture 5).
The chimney cap must meet the following requirements:
