SMOKE OUTLET
The boiler must have its own smoke outlet (the smoke can-
not be discharged into a smoke fl ue used by other devices).
In Germany, discharge can be by multiple fl ue with explicit
verifi cation on the part of a chimney-sweep.
The smoke is discharged through the 10 cm diameter outlet at
the back of the boiler.
A T-junction must be set up with a condensation collection
stopper at the beginning of the vertical section.
The smoke outlet must be connected to outside by means of
suitable steel pipes EN 1856 certifi ed.
All piping must be hermetically sealed and, if necessary, insu-
lated.
To seal the various elements of the piping together, materials
resistant to high temperatures must be used (silicon or mastics
for high temperatures).
The pipe must be hermetically sealed.
The material used to seal and if necessary insulate the pipes,
must be resistant to high temperatures (high temperature silico-
ne or mastic).
The only horizontal section allowed may be up to 2 m long.
It may have up to three 90° bends.
If the outlet is not fi tted into a chimney fl ue, a vertical section
and a wind guard are required (reference UNI 10683/2012).
The vertical duct can be internal or external.
If the smoke channel (part of the pipe that goes from the boiler-
stove to the chimney fl ue) is outside, it must be appropriately
insulated.
If the smoke channel is fi tted inside a chimney fl ue, the latter
must be suitable for solid fuel.
If it is wider than 150 mm in diameter it must be improved by
entering a pipe that has a suitable cross-section and is made of
suitable material (e.g. 100 mm diameter steel).
All sections of the smoke duct must be accessible for inspec-
tion.
If it is not removable, it must have inspection holes to allow for
cleaning.
The boiler is designed to operate under any weather conditions.
In the case of particular conditions, such as strong winds, safe-
ty systems may intervene that extinguish the boiler.
In this case, do not operate the appliance while the safety devi-
ces are disabled.
If the problem persists, contact the Service Centre.
CHIMNEY POT
The main characteristics are:
- an internal cross-section at the base, which is the same as that
of the chimney fl ue
- an outlet cross-section which is no smaller than twice that of
the chimney fl ue
- its position must be high enough to catch the wind and avoid
downdraft areas in turbulent wind.
