temperature and condensate;
– be of adequate mechanical resil-
ience and of low heat conductivity;
– be perfectly sealed to prevent cool-
ing of the flue itself;
– be as vertical as possible; the ter-
minal section of the flue must be
fitted with a static exhaust device
that ensures constant and efficient
extraction of products generated by
combustion;
– have a diameter that is not inferior
to that of the boiler union;
– to be properly sized to meet the flue
gas draught/exhaust requirements
necessary for regular operation of
the product (EN13384-1);
- a specific condensate outlet system
must be installed at the bottom of
the flue;
- rigid pipes must be used for the
connection to the flue, resistant to

WATER TRAP
(fig. 5)
The drip board and its water trap
must be connected to a civil drain
through a pipe (ø 25) with a slope of
at least 5 mm per metre to ensure
drainage of condensation water.
The plastic pipes normally used
for civil drains are the only type
of pipe which is appropriate for
conveying condensation to the buil-
ding's sewer pipes.

ELECTRICAL
CONNECTION (fig. 5/a)
The boiler is fitted with an electricity
cable, and requires a a single-phase
power supply of 230V - 50Hz through
the main switch protected by fuses.
The room thermostat (required for
enhanced room temperature con-
trol) should be installed as shown in
fig. 5/a. Connect the burner and sys-
tem circulation pump power cables
supplied.
NO TE: Device must be connected to
an efficient earthing system.
SI ME de cli nes all responsibility for
injury caused to persons due to
failure to earth the boiler.
Always turn off the power supply
before doing any work on the elec-
trical panel.
