INSTALLATION
FLUE CONNECTION
Operation related to the ambient air
(Type B23 Installation)
To ventilate the boiler room, it is required to install- in accordance with combustion regulations - a
fresh air inlet of at least 150 cm
2
or to provide a connection with other rooms to ensure a fresh air
supply.
To get optimum sound comfort, it is
recommended to:
- install the boiler on a solid base (eg.
concrete support) instead of a hollow base
(eg. concrete blocks), which could create a
resonance volume.
- uncouple the boiler from the system
hydraulic circuit by installing a hose
connection on the inlet and outlet circuits
and make sure that the hose connections
are not taut or twisted.
- increase the gas exhaust duct diameter if
required (min 80 mm diameter).
- uncouple the gas exhaust circuit from
the flue pipe wall, adding soft insulation
between the pipe and the wall, so that the
vibrations from the operating boiler are not
transferred to the building walls.

Measuring port
Measurements of the flue gases can only
be taken at the measuring port.
In normal operation of the boiler, the port
must be closed at all times.
