suction diaphragm which must be used as
specified in figure 14, depending on the
maximum acceptable loss.
The maximum length of the duct is deter-
mined by the load losses of the single
accessories fitted (excluding the splitter)
and should not exceed 7.00 mm H2O (“25
BF TS”) and 8.00 mm H2O (“30 BF TS”).
For information on how to calculate the load
of single accessories, see Table 1.
2.11 POSITIONING THE OUTLET
TERMINALS
The outlet terminals for forced-draught
appliances may be located in the external
perimeter walls of the building.
To provide some indications of possible solu-
tions, Table 2 gives the minimum distances
to be observed, with reference to the type
of building shown in fig. 18.
2.12 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.
2.12.1 Electric switchboard
To access the electrical panel, turn off the
power supply and then remove the front
panel and the two screws that anchor the
control panel to the sides(see point 4.7).
The panel will tilt forward at a sufficient angle
to allow access to the components.
To remove the protection, unscrew the fixing
screws and use a screwdriver to release the
upper tabs and free it from the control panel
(fig. 19).

TABLE 2
1) Terminals below a practicable balcony must be located in such a way that the
total path of the smoke from its outlet point from the terminal to its outlet point
from the external perimeter of the balcony, including the height of possible rai-
lings, is not less than 2000 mm.
2) When siting terminals, where materials that may be subject to the action of the
combustion products are present in the vicinity, e.g., eaves, gutters and down-
spouts painted or made of plastic material, projecting timberwork, etc., distan-
ces of not less than 1500 mm must be adopted, unless adequate shielding is
provided to guard these materials.
Siting of terminal Appliances from 7 to 35 kW

A - below openable window 600
B - below ventilation opening 600
C - below eaves 300
D - below balcony (1) 300
E - from adjacent window 400
