(*) 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:
25R: 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.
35R: 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.

Filling the heating system (fig. 16)
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 (outside the boiler) until the pressure indicated by the
water pressure gauge is between 1 and 1.5 bar
- re-close the filling tap (outside the boiler).
b
The venting of the boiler takes place automatically via the two
automatic vent valve A positioned on the circulator.
3.10 Draining the heating system (fig. 16)
Before starting emptying, switch off the electricity supply by turning off the
main switch of the system.
- Close the heating system's valves.
- Connect a hose to the system drain valve (B).
- Manually loosen the system drain valve (B).
3.11 Circulator settings
Circulator residual discharge head
The boilers is equipped with an already hydraulically and electrically
connected circulator, whose useful available performance is indicated in
ΔP at
the graphs at page 43.
boiler
The circulator comes set from the factory with a 6 metre discharge head curve.
output
The boiler is equipped with an anti-blocking system which starts up an
Pa
operation cycle after every 24 hours in standby with the mode selector in
180
any position.

b
255
The "antiblocking" function is active only if the boiler is electrically
powered.

If you need to use a different curve you can select the desired level on the
circulator.

The user interface allows the operating performance to be viewed (operating
430
status and alarm status) and it also allows the circulator operating modes
to be set.
480
The performance, indicated by the LEDs (B) and (C) is always visible during
510
normal operation of the circulator whereas the settings can be carried out
by pressing the button (A).
3.11.2
Operating status indication
When the circulator is in operation the LED (B) is green. The four yellow
LEDs (C) indicate the electrical energy consumption (P1) as shown in the
following table.
