the pipe. The usable height of the water
trap must be at least 150 mm.

FORCED EXHAUST
(Type B23P-53P)
This type of exhaust pipe is installed using
the special kit, code 8089912/13. For kit
assembly instructions, refer to point 2.6.
Protect the intake with the optional acces-
sory, code 8089501.
The accessory is assembled by cutting a 50
mm long segment from an ordinary ø 80
extension and inserting it on the air intake,
on which the accessory is then fitted,
anchored to the pipe segment with the
screws provided (fig. 9/a).
Maximum flow resistance must be no
more than 10 mm H

O (ver-
sion 25-30-35) (ATTENTION: the total
length of each pipe should not exceed 50
m, even if the total loss is below the maxi-
mum applicable loss.)
As the maximum pipe length is determined
by adding up the flow resistance of the
various individual accessories installed,
refer to
Table 1-1/a
for calculation.

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 3
gives the minimum distances
to be observed, with reference to the type
of building shown in fig. 10.
2.9
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.
Respect the L and N polarities and the

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 downspouts painted or made
of plastic material, projecting timberwork, etc., distances of
not less than 1500 mm must be adopted, unless adequate
shielding is provided to guard these materials.
