The main factors to be taken into conside-
ration for calculating the section are the
heat input of the boiler, the type of fuel, the
percentage of CO 2 , the mass flow of smoke
at nominal load, the temperature of the
smoke, the roughness of the internal wall,
and the effect of gravity on the draught
pressure, which must take into account the
external temperature and the altitude.
2.6 ELECTRICAL
CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME. The elec-
tric power supply to the boiler must be
230V-50Hz single-phase through a fused
main switch, with at least 3 mm spacing
between contacts.
The room stat must be class II as specified
by standard EN 60730. 1 (clean contact).
NOTE: Device must be connected to an
efficient earthing system.
SIME declines all responsibility for injury
or damage to persons, animals or things,
resulting from the failure to provide for
proper earthing of the appliance.
Always turn off the power supply before
doing any work on the electrical panel.
2.6. 1 Control system
connection (optional)
In the electrical circuit a series of connec-
tors are provided for the installation of an
optional control system, marked by differ-
ent colours black, red and brown (fig. 5).
The connectors are polarised in such a way
that the order cannot be inverted. To install
the control system these connectors must
be connected and jumpers 4-5 and 11-12
must be removed from the terminal board
(marked in bold in fig. 6).
The control sustem allows for the use of
sensors and environment units whose con-
nectors, polarised and coloured, are found
in a bag inside the control board.
