FORCED EXHAUST
(Type B22P-52P)
Comply with the following requirements
during installation:
– Insulate the exhaust pipe and install a
condensation collection system at the
base of the vertical pipe.
– If the pipe passes through combustible
walls, insulate the section of the flue pipe
passing through the wall with a 30 mm
thick fibreglass pipe covering with a den-
sity of 50 kg/m

.
In "25 BF TS" models this type of exhaust
pipe is installed using the special kit, code
8089904. For kit assembly instructions,
refer to point 2.9. 1 . Protect the intake with
the optional accessory, code 8089501. The
accessory is assembled by cutting a 50 mm
long segment from an ordinary ø 80 exten-
sion and inserting it on the air intake, on
which the accessory is then fitted, anchored
to the pipe segment with the screws provi-
ded (fig. 10). Kit code 8089904 is supplied
with the intake diaphragm, which must be
used as shown in fig. 8/a, depending on the
maximum permitted flow.
Maximum flow resistance must be no
more than 7.6 mm H
O.

As the maximum pipe length is determined
by adding up the flow resistance of the
various individual accessories installed, refer
to Table 1 for calculation.

POSITIONING OF OUTLET
TERMINALS
The outlet terminals for forced draught
systems may be located on the outer walls
TABLE 2
Siting of terminal
A - below openable window
B - below ventilation opening
C - below eaves
D - below balcony (1)
E - from adjacent window
F - from adjacent ventilation opening
G - from horizontal or vertical soil or drain pipes (2)
H - from corner of building
I - from recess in building
L - from ground level or other treadable surface
M - between two terminals set vertically
N - between two terminals set horizontally
O - from a surface facing without
openings or terminals
P - as above but with openings and terminals
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 termi-
nal to its outlet point from the external perimeter of the balcony,
including the height of possible railings, 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 downspouts painted or made of plastic mate-
rial, projecting timberwork, etc., distances of not less than 1500
mm must be adopted, unless adequate shielding is provided to
guard these materials.

non-binding minimum distances to be met
for a building of the type shown in fig. 11.

ELECTRICAL WIRING
If you must replace the electric power
cable supplied with the boiler, order it exclu-
sively from Sime.
The power supply must be single-phase
230V - 50 Hz through a main switch pro-
tected by a fuse with a distance of at least
3 mm between contacts.

NOTE: The boiler must be con-
nected with an efficient groun-
ding system. SIME shall not be
held liable for injury or damage resulting
from failure to ground the boiler.

Electrical panel (fig. 12)
Before performing any kind of operation, discon-
nect the unit from the power supply using the
bipolar switch of the plant. Placing the boiler
selector in position "OFF" does not discon-
nect the electric board from the power
