FORCED OUTLET
The "25 BF" version can also be installed as
a B
type apparatus by assembling the
22
stub pipe inlet/outlet kit cod. 8089950.
The kit comes with a sector diaphgram,
instruction sheet and a label with the room
aeration warnings to be attached to the boi-
ler casing. The sector diaphram must be
used according to the maximum load loss
allowed by the duct, as indicated in fig. 14.
The complete range of fittings required to
carry out the installation is given in fig. 18.
The maximum length of the duct is deter-
mined by the load losses of the single atta-
ched fittings (excluding the inlet/outlet
stub pipe) and should not be greater than
8.00 mm H
O.

To calculate the load loss of the individual fit-
tings attached see Table 2.

ELECTRICAL CONNECTION
The boiler is supplied with an electric cable.
Should this require replacement, it must be
purchased exclusively from SIME.
The electric power supply to the boiler must
be 230V~50Hz single-phase through a
fused main switch, with at least 3 mm spa-
cing between contacts.
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.
