Twin pipes with Ø 80 pipework (Ø50 - Ø60 - Ø80) (Fig. 17)
Thanks to the boiler characteristics, a Ø80 flue gas exhaust pipe can be connected to the Ø50
- Ø60 - Ø80 piping ranges.
b
For the pipe, you are advised to make a project calculation in order to respect the rele-
vant regulations in force.
The table shows the standard configurations allowed.

(*) Use flue gas system accessories made of plastic (PP) for condensing boilers: Ø50 and Ø80
class H1 and Ø60 class P1.
The boilers are factory set to:
25 KIS: 6,200 r.p.m. in heating mode and 7,600 in domestic hot water mode and the maximum
attainable length is 5m for the Ø 50 pipe, 18 m for the Ø 60 pipe and 98 m for the Ø 80 pipe.
30 KIS: 5,800 rpm in heating mode and 6,900 in domestic hot water mode, and the maximum
length that can be reached is 2m for the Ø50 and 11 m for the Ø60 pipe and 53 m for the Ø80
pipe.
35 KIS: 6,900 rpm in heating mode and 7,800 in domestic hot water mode, and the maximum
length that can be reached is 2m for the Ø50 pipe and 11 m for the Ø60 pipe and 57 m for the
Ø80 pipe.
40 KIS: 6,900 rpm in heating mode and 9,100 in domestic hot water mode, and the maximum
length that can be reached is 7m for Ø60 pipe and 42m for Ø80 pipe (not applicable for Ø50
pipe).
Should greater lengths be required, compensate the pressure drop with an increase in the
r.p.m.of the fan, as shown in the adjustments table, to provide the rated heat input.
b
The minimum calibration should not be modified.

The Ø50 or Ø60 or Ø80 configurations contain Lab test data. In the event of installations that
differ from the indications in the "standard configurations" and "adjustments" tables, refer to the
equivalent linear lengths below.

In any case, the maximum lengths declared in the booklet are guaranteed, and it is
essential not to exceed them.

3.16 Installation on collective flues in positive pressure (fig 18)
The collective flue is a flue gas exhaust system suitable for collecting and expelling the combu-
stion products of several appliances installed on several floors of a building.
The positive pressure collective flues can only be used for type C condensing appliances. The-
refore the B53P/B23P configuration is forbidden. The installation of boilers under collective pres-
sure flues is allowed exclusively in G20.
The boiler is sized to operate correctly up to a maximum internal pressure of the flue no higher
ΔP at boiler
than the value of 25 Pa. Check that the fan speed corresponds to what is shown in the table
outlet
"technical data".
Pa
Make sure that the air intake and exhaust pipes of the combustion products are watertight.
174
WARNINGS:
213
b
The appliances connected to a collective pipe must all be of the same type and have
253
equivalent combustion characteristics.
292
b
332
The number of devices connected to a positive pressure collective pipe is defined by
371
the flue designer.
410
The boiler is designed to be connected to a collective flue sized to operate in conditions where
the static pressure of the collective flue pipe can exceed the static pressure of the collective air
450
duct of 25 Pa in the condition in which n-1 boilers work at maximum rated heat input and 1 boiler
489
at the minimum rated heat input allowed by the controls.
528
b
The minimum permissible pressure difference between the flue gas outlet and the com-
150
bustion air inlet is -200 Pa (including - 100 Pa of wind pressure).
189
For both types of exhaust, further accessories are available (curves, extensions, terminals, etc.)
229
which make possible the flue gas exhaust configurations foreseen in the boiler booklet.
b
268
The pipes must be installed in such a way as to avoid condensation sticking which would
308
prevent the correct evacuation of the combustion products.
347
b
386 A data plate must be present at the connection point with the collective flue pipe. The
plate must include at least the following information:
426
- the collective flue is sized for boilers C(10) type
465
- the maximum permissible mass flow of the combustion products in kg/h
504
- the dimensions of the connection to the common pipes
190
- a warning concerning the openings for the air outlet and the entry of the combustion
products of the collective pressure pipe; these openings must be closed and their
229
tightness must be checked when the boiler is disconnected
269
- the name of the manufacturer of the collective smoke pipe or its identification symbol.
b
308
See applicable legislation for the discharge of the combustion products as well as local
348
regulations.
387

The flue gas pipe must be suitably selected based on the parameters shown below.
