Smoke outlet and combustion air inlet

Sime ESTELLE HE ErP are classified as "Type B" (B23P) and ES-
and 4 ErP models can be converted, during the
TELLE HE 3 ErP
installation phase, to "Type C" (C23P) by applying a specific ac-
cessory.
The fume discharge and combustion air intake system must be
made as explained below.

IT IS FORBIDDEN
– Do not block or reduce the size of the air vents of the
place of installation or the appliance.
"TYPE B" installations
The combustion air must be drawn through a permanent open-
ing, which MUST be present in the room where the appliance is
installed and MUST be made in accordance with the standards
and laws in force in the country where the appliance is used.
B23P
The flue is extremely important for the proper operation of the
installed device. If it is not carried out with the appropriate cri-
teria, burner malfunctions and noise amplification may occur, in
addition to the build-up of soot, condensate and encrustations.
A flue must therefore fulfil the following requirements:
– it must be made of waterproof material resistant to the fume
– it must have sufficient mechanical resistance and low ther-
– it must be perfectly sealed to prevent cooling of the flue itself
B
– it must be as vertical as possible, and the end part must have
– in order to prevent wind from creating pressure zones around
Øi
– The flue diameter must not be smaller than that of the boiler
C
"TYPE C" installations
This type of installation can only be made with ESTELLE HE 3 ErP
and ESTELLE HE 4 ErP boilers converted with the accessories kit
code 8098816 to be purchased separately from the boiler.

0,4m from any structure adjacent to the flue itself (including
the ridge of the roof) within a distance of 8 m

the inner section must be increased by 10% with respect to
the section of the boiler coupling.
