3.15 CONNECTING THE FLUE
Exhaust is discharged at very low temperatures (Max 84°C approx) in
condensation boilers. It is therefore necessary for the flue to be perfectly
impermeable to combustion product condensate and built with suitable
corrosion-resistant materials.
The various slip on joints must be well-sealed and equipped with suitable
gaskets to stop condensation from leaking out and air from getting in.
In terms of flue section and height, it is necessary to refer to national
and local regulations in force.
Refer to regulations in force for sizing.
In order to avoid the formation of ice during operation, the temperature
of the inside wall at every point in the combustion product evacuation
system, for its entire length, must not drop below 0°C.
For condensation operating conditions of the appliance at project
outdoor temperatures, it will be necessary to build a confluent
condensate drainage system, based on the installation conditions, either
to the boiler collection tank or separate from it.
The flue exhaust pipe must comply with local and national
regulations.
The evacuation pipe must be built using materials that are resistant
to the combustion products, typically class W1 certified stainless
steel or plastic materials.
Such as PVDF (polyvinyldimethylfluoride) or PPS (simple translucent
polypropylene) or aluminium or other materials with the same features,
in observance of regulation in force.
The supplier is excluded from any contractual and
extra-contractual liability for damage caused by
errors in installation and use and nevertheless due
to failure to observe the instructions provided by
the manufacturer.

3.16 FLUE EXHAUST MANIFOLD
CONNECTION
To secure the flue exhaust manifold use the 10 nuts +
CH 10 washers contained in the bag.
The flue point must be positioned on the first straight
section, within 1 meter of the boiler.
To set up the flue inspection point, cut a Ø 21 mm hole
in the flue exhaust pipe, and install the inspection point
following the sequence provided.
