Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80 (fig. 15a)
Thanks to the boiler characteristics, a flue gas discharge pipe ø 80 can
be connected to the ducting ranges Ø50 - Ø60 - Ø80.
b
For the ducting, you are advised to make a project calculation in
order to respect the relevant standards in force.
The table shows the standard configurations allowed.

(*) Use flue gas system accessories in plastic (PP) for condensing boilers:
Ø50 and Ø80 H1 class and Ø60 P1 class.
The boilers are factory set to:
25C: 5.600 r.p.m. (CH) and 7.900 r.p.m. (DHW) and the maximum length
that can be reached is 6m for the ø 50 pipe, 21m for the ø 60 pipe and 115m
for the ø 80 pipe.
30C: 6.500 r.p.m. (CH) and 7.900 r.p.m. (DHW) and the maximum length
that can be reached is 4m for the ø 50 pipe, 16m for the ø60 pipe and 83m
for the ø 80 pipe.
35C: 6.900 r.p.m. (CH) and 7.800 r.p.m. (DHW) and the maximum length
that can be reached is 1m for the ø 50 pipe, 10m for the ø60 pipe and 54m
for the ø 80 pipe.
Should it be necessary to achieve greater lengths, compensate the pressure
drop with an increase in the r.p.m.of the fan, as shown in the adjustments
table, to ensure the rated heat input.

The minimum calibration is not modified.

Filling the heating system (fig. 16)
Note: even if the boiler is fitted with a semi-automatic filling device, the
first filling operation must be carried out by turning the filler tap (B) with the
boiler off.
Once the hydraulic connections have been carried out, fill the heating
system. This operation must be carried out when the system is cold,carrying
out the following operations:
- open the caps of the lower (A) automatic air vent valve by two or three
turns; to allow a continuous venting of the air, leave the plug of the valve
A open
- make sure the cold water inlet tap is open
- open the filling tap (B) until the pressure indicated by the water pressure
gauge is between 1 and 1.5 bar
- re-close the filling tap.
b
The venting of the boiler takes place automatically via the two
Pa
automatic vent valve A positioned on the circulator.

3.10 Draining the heating system (fig. 16)
210
Before starting emptying, switch off the electricity supply by turning off the
255
main switch of the system.
280
- Close the heating system's valves.
325
- Connect a hose to the system drain valve (C).
365
- Manually loosen the system drain valve (C).

3.11 Emptying the domestic hot water system
450
Whenever there is risk of frost, the domestic hot water system must be
490
emptied in the following way:
523
- turn off the main water supply tap
- turn on all the hot and cold water taps
562
- drain the lowest points.

Circulator residual discharge head
225
The boilers is equipped with an already hydraulically and electrically
270
connected circulator, whose useful available performance is indicated in
310
the graphs at page 42.
350
The circulator comes set from the factory with a 6 metre discharge head curve.
The boiler is equipped with an anti-blocking system which starts up an
390
operation cycle after every 24 hours in standby with the mode selector in
420
any position.
460
b
495
The "antiblocking" function is active only if the boiler is electrically
540
powered.
a
161
Operating the circulator without water is strictly forbidden.
190
If you need to use a different curve you can select the desired level on the
circulator.
225
Below the main characteristics and the ways to set up their desired operation
255
are listed.

The user interface is made up of a button (A), a two-coloured red / green
400
LED (B) and four yellow LEDs (C) arranged in a row.
