1.1.16. TYPES OF INSTALLATION
For this type of boiler are available the following
fumes discharge configurations: B11BS (see Fig. 1).
› B11BS:
· Type B, open chamber boiler, equipped with a
control device for the evacuation of combustion
products (flue safety thermostat).
· Air intake in the environment and flues
exhaust to the outside.
· For the minimum chimney height allowed,
refer to the ‘TECHNICAL DATA’ paragraph.
DISCHARGE OF COMBUSTION PRODUCTS FOR
B-TYPE DEVICES.
The gas devices, provided with connection for
fumes exhaust tube, must be directly connected to
efficient chimneys or fume exhaust ducts: only if
these are missing you can discharge the combustion
products directly through the gas devices.
The connection to the chimney or to the fume
exhaust ducts must respect the following
requirements:
· Be sealed and realised in materials suitable
to resist normal mechanical stress, heat,
the action of combustion products and any
condensate forming;
· have no more than three changes in direction,
including the chimney and/or fume exhaust
duct inlet connection, made with internal
angles greater than 90°. The changes in
direction must be made only by using curved
curved elements;
· have the axis of the inlet end perpendicular to
the internal wall opposite to the chimney or
fume exhaust duct;
· have, along its entire length, a section equal
to or greater then that of the connection of the
device discharge tube;
· have no shut-off devices (shutters).
· for direct external discharge there must be no
more than two changes in direction.
LOCATIONS VENTING FOR B-TYPE DEVICES
The locations in which are installed gas devices
must be vented so as to ensure the amount of air
necessary for a regular combustion and for location
ventilation. The natural air intake must take place
directly through:
