CONDENSINOX -
Installation, Use and Maintenance
4.4.
Exhaust connection
It is essential to comply with the regulations and codes of practice in force in
the country where the boiler is installed.
An exhaust temperature sensor guarantees protection for type B and C
combustion product evacuation flues.
4.4.1. Connection to a B23 chimney
B23 type connection:
Air from the installation room, gas evacuation through the roof via a natural
draft duct.
ATTENTION:
Ensure that the room where the boiler is installed has high and low
ventilation outlets in accordance with the regulations in force and
that they are not obstructed.
For the
CONDENSINOX 40-50-60
, the use of the
ø
125 Chimney Adaptor
accessory (code 040940) is mandatory to connect a CONDENSINOX boiler to a
B23 chimney duct. This kit is suitable for Ø 125 exterior ducts.
For the
CONDENSINOX 80-100
, the use of the
ø
160 Chimney Adaptor
accessory (code 041050) is mandatory to connect a CONDENSINOX boiler to a
B23 chimney duct. This kit is suitable for Ø 160 exterior ducts.
ATTENTION:
Under no circumstances is use of these mandatory accessories a
substitute for checking the dimensioning of the chimney ducts (given
a combustion gas pressure at the boiler outlet equal to 0 Pa).
The exhaust extraction ducts must be made in a material resistant to the
condensate that can form when the boiler is operating.
These materials
must also be capable of supporting exhaust temperatures up to 120°C.
CONDENSINOX boilers are high-performance boilers with very low exhaust
temperatures; consequently to retain a favourable draft the ducts must run
upwards from the boiler outlet.
Horizontal duct runs must be avoided so as not to cause condensate retention.
Use a minimum slope of 3% towards the boiler in the horizontal parts.
IMPORTANT:
If several boilers are connected to the same flue, make sure:
1. By calculation, that the flue is not under pressure when all the
boilers are operating.
2. If one of the boilers is operating at minimum power, that the
others do not discharge into it.
