SYSTEM FILLING

Filling of the boiler and the system is done by
installing a pressure reducing valve. The char-
ge pressure, with the system cold, must be
between 1 and 1.2 bar (14.5 and 17.4 psi).
During system filling you are recommended to
keep the main switch turned OFF. Filling must
be done slowly so as to allow any air bubbles to
be bled off through the air valves. Should the
pressure have risen well above the limit expec-
ted, discharge the over pressure by opening
the pressure-relief valve. Bleed pump by loosen
plug at back of motor. Once air is removed re-
tighten plug. It may be necessary to free the
pump motor before filling the system. This is
done by removing the pump plug and turning
the pump shaft loose. Do not forget to re-tigh-
ten pump plug before filling system.
See typical piping in the figure below.
2.4. 1 Emptying the system (fig. 5)
Use the drain tap to empty the system (9).
Turn off the boiler before doing this.

FLUES/CHIMNEYS

The flue or chimney used to release the pro-
ducts of combustion into the atmosphere

must comply with current standards and regu-
lations. Horizontal vent lengths must be sup-
ported every I meter (39 in) or less to prevent
sagging.
2.5. 1 Passing flue pipes through
an existing chimney
When renovating or passing flue pipes throu-
gh an existing chimney, use only flues which
are declared suitable for the purpose by the
manufacturer, following the instructions for
installation and use provided by the manufac-
turer.
2.6 INSTALLATION COAXIAL PIPE (fig. 6)
The air inlet-smoke outlet assembly ø 60/100
is supplied in a kit code 8084811 complete
with mounting instructions.
With the curve supplied in the kit the maxi-
mum horizontal length of the flue must not
exceed 4 m (13 ft).
The diagrams in fig. 6 illustrate a number of
examples of different coaxial outlets.
2.6. 1 Coaxial flue diaphragm (fig. 6/a)
The boiler is supplied as standard with a ø 86
diaphragm. With outlet type C12, install diaph-
ragm ø 86 mm (3.4 inch) only if the coaxial
flue is less than 1 metres (3.3 ft) long.
For C32 discharge options, it is necessary to
order the optional diaphragm separately and
use it in accordance with the instructions pro-
vided in figure 6/a.

INSTALLATION SEPARATE PIPES

The smoke pipe must be certified ø 3" cate-
gory III venting. When installing the pipes,
follow closely the requirements of the cur-
rent standards and regulations, as well as
the following practical pointers:
1. With direct intake from outside, when
the pipe is longer than 1 m (3.3 ft), you
are recommended to insulate the piping
so as to prevent formation of dew on
the outside of the piping during particu-
larly hard periods of the year.
2. With the outlet pipe outside the building
or in cold indoor environments, insula-
tion is necessary to prevent burner fai-
lure during trial for ignition. In such
cases, provide for a condensate-collec-
tor system on the piping.
3. If a segment of the flue passes through
a flammable wall, this segment must be
