5.13 - Flue systems
ATTENTION !!! The relevant national and local
regulations must be strictly adhered to when installing
the exhaust flue and combustion air pipes.
ATTENTION !!! The exhaust flue gases from
the appliance can reach 90°C in certain conditions.
Therefore, the plastic flue components must be capable
of withstanding high temperatures and they must be
approved for these specific appliance.
ATTENTION !!! This appliance is the
“condensing” type. The polypropylene materials used
in the manufacture of plastic exhaust flue system
which are approved for use are designed to prevent
corrosion which would otherwise be caused to the
acidity of the condensate. AISI316 stainless steel
exhaust flue system can also be designed for this
purpose.
Regarding this, remember that the appliances of this
type must have exhaust and intake pipes supplied by the
manufacturer of the appliance itself. Other types of pipes,
if used, must however be type-approved for this intended
use. The types of exhaust for which the appliance is
approved are given in the features table at the end of the
manual under “type” and o the features plate affixed to the
appliance, also under “type”. The symbols used to define
exhaust is reported below:
- B23, separated with intake in room and exhaust through
wall or roof.
ATTENTION !!! If the appliance is installed with the
B23 type exhaust, it will take in air for combustion from
the surrounding environment. Therefore, all precautions
must be taken regarding ventilation of the rooms, which
are prescribed by the national and/or local Standards.
- C13, coaxial in vertical wall
- C33, coaxial at the roof
- C43, separated with exhaust in flue, combined with intake
in common channel.
ATTENTION !!! The appliances installed in type
C43 must only be connected to conventional flues.
- C53, separated with exhaust on roof and intake on wall or
however, in two potentially different pressure points.
- C63, the appliance can be fitted to type-approved exhaust
and intake pipes of other brands.
ATTENTION !!! With the C63 type exhaust,
the condensate coming from the chimney cannot be
conveyed into the appliance.
- C83, separated with wall intake or another point
independent from the intakes of other appliances and
flue exhaust.
