m
CAUTION
The total maximum length is obtained by adding the
length of the inlet and outlet pipes. The total load loss is
determined by the sum of the load losses of the single
accessories that make up the pipework. It should not
exceed 15 mmH
2
O. The total extension for each single
duct must not in any case exceed 25 m, even if the to-
tal load loss is less than the maximum which can be
applied.
NOTE:
for the boiler to operate correctly it is necessary that a
minimum distance of 0.50 m of the duct is respected with a 90°
inlet curve.
Example: calculation of the load loss of a

boiler.

6.13 Electrical connections
The power cable must be connected to a 230V (±10%) ~ 50 Hz
network, observing L-N polarity and the earth connection. The
network must have an omnipolar switch with category III over-
voltage, in compliance with the installation rules.
If this cable needs to be replaced, an original spare must be re-
quested from
Sime
.
Therefore only the connections of the original components as
shown in the table are needed. These are to be ordered separate-
ly from the boiler.
