IMPORTANT:
The above values are provided for information purposes only. It is
important to check them with a calculation.
!
IMPORTANT:
The weight of fl ue-gas ducts must not be supported by the part
connecting to the boiler.
4.10.2. Connection to a B23P chimney
Type B23P connection:
Air coming from the boiler premises, extraction of gases through the roof via
a pressurised duct.
!
IMPORTANT:
For the B23P type connection, it is MANDATORY to use ducts which
have pressurised duct certi
fi cation, such as CONDENSOR (Poujoulat)
or rigid or fl exible CHEMILUX CONDENSATION (Ubbink).
!
IMPORTANT:
The duct extracting combustion products must be sized using the
parameters provided in the table in paragraph 3.3.
Depending on the duct's actual con
fi guration, a calculation is
necessary to check that the pressures at the boiler outlet do not
exceed the maximum normative values authorised (200 Pa).
Values corresponding to the 50/30°C regime are to be used for this
calculation.
!
WARNING:
Check that there are top and bottom ventilations in the boiler premises,
that they comply with applicable regulations and that they are not
obstructed.
