gas main pipes.
To prevent malfunctioning of the valve, or
in certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.
2.4 INITIAL PHASE
SYSTEM FILLING
The charge pressure, at cold start, must
be 1 bar.
The filling is to be done slowly to allow air
bubbles to escape through the air vents.
2.4.1 System draining
(fig. 5)
To drain the system, turn off the boiler and
use the discharge valve (2 fig. 5).
2.5 EXHAUST
The boiler is supplied with a 80 mm gasket,
which must be fitted over the exhaust ter-
minal prior to the flue being installed (11
fig. 4/b - 4/c - 4/d).
2.5.1 Type B (fig. 6)
If the inlet is not connected, the boiler
should be regarded a Type B device.
When installing the boiler in locations
where it needs to be protected from water,
replace the intake terminal inserted in the
flange with terminal code 8089510.
KEY
1 Condensate drain tap
2 Boiler discharge
3 Safety valve 5 bar
For information on how to configure the
boiler in this mode see figure 6.
WARNING: The maximum overall length
of ø 80 exhaust flues is determined by
the load losses of the single accessories
installed and should not exceed 42 mm
H O.
2
When load loss exceeds 4 mm H
order to assure the correct operation of
the appliance, set the installer parameter
PAR 9 as indicated in TABLE 1 (see point
3.3 to access installer parameters).
The exhaust pipe can be connected to exi-
sting chimneys.
When the boiler works at low temperature
is possible to use normal chimneys at the
following conditions:
– The chimney must not be used by other
boilers.
– The inside of the chimney must be pro-
tected from direct contact with the boi-
ler condensation. Combustion products
must be conveyed with a flexible piping
or rigid plastic pipes with a diameter of
about 100-150 mm providing so to the
condensation siphoned drainage at the
end of the pipe. The useful height of the
siphon must be at least 150 mm.
2.5.2 Type C (fig. 7 - fig. 8)
The boiler becomes a Type C device when
the intake terminal is removed from the
flange and the intake is connected to sepa-
rate exhaust ducts (fig. 7) or with coaxial
exhaust (fig. 8).
2.5.3 Maximum usable length
for separate ø 80 flues
The maximum overall length of ø 80 suc-
tion and exhaust flues is determined by
the load losses of the single accessories
installed and should not exceed 42 mm
H O.

order to assure the correct operation of
the appliance, set the installer parameter
PAR 9 as indicated in TABLE 2 (see point
3.3 to access installer parameters) and
proceed with calibrating CO
mum and minimum capacity as specified
in point 4.2.2.
2.5.4 Maximum usable
length for coaxial ø 80/125 flues
In installations with ø 80/125 coaxial
exhaust, the maximum horizontal length
including the 90° curve, should not exceed
4 m when the boiler is supplied at the G20
and 3 m when it is supplied G31.
In roof exhausts, it must not be greater
than 5 m straight vertical lines when the
boiler is supplied at G20 and 4 m when
supplied at G31.
WARNING:
In order to assure the correct operation of
the appliance, set the installer parameter
PAR 9 as indicated in TABLES 3-3/a (see
point 3.3 to access the installer parame-
ters) and proceed with calibrating CO
the maximum and minimum capacity as
specified in point 4.2.2.
