3.4 Flue Pipe (ref. UNI 10683)
The flue pipe must meet the following re
-
quirements:
•
Twin wall steel flue, required diame
-
ter is 100 mm round for 24 kW mo-
dels or 130 mm for 34 kW models,
regardless of external or internal in-
stallation of the duct;
• It must be resistant to heat, mecha-
nical stress, heat, combustion resi-
dues and related condensate;
• It must be installed at a safe distance
from eventual combustible materials;
• It must have draft between 11 and
15 Pa.
The proper draught conditions in the
flue is critical for the efficient wor
-
king of pellet boilers/thermostoves.
All sections of the flue must be ca
-
pable of inspection and removable to
enable periodic internal cleaning.
The boiler must be connected to a
flue pipe or a vertical duct which can
discharge the fumes at the highest
point of the building, conforming to
current national regulations. Failu-
re to comply can lead to the termi-
nation of the guarantee and of the
manufacturer’s responsibility for the
product.
3.5 Flue gasses discharge
To discharge the flue gas outside, make a
hole of an adequate size to the flue pipe.
A T-element with inspection cap and
chimney cowl
must be installed on the
flue pipe run.
Maximum two accessible 90° bends are al-
lowed on the flue pipe, each of them must
have a T-fitting with inspection cap. Maxi
-
mum permissible flue lengths are 3 meters
with an upward slope of 3%.
Flue gasses discharge on the wall is
not permitted by current regulations.
Failure to comply can lead to the ter-
mination of the guarantee and of the
manufacturer’s responsibility for the
product.
Smoke exhaust with existing flue
A chimney cleanout access door is required.
Control and periodically clean the chimney.
Chimney terminal position
For the installation of smoke exhaust
ducts consult the technical regulations UNI
10683. As shown on the
fig.2
, the terminal
of the chimney over the roof must have the
following quotes (b>10°):
- a = 500mm
- c = 1300 mm.
