3.15 Installation on collective flues in positive
pressure (fig 18)
The collective flue is a flue gas exhaust system suitable for collecting
and expelling the combustion 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. Therefore the B53P/B23P configuration is forbidden. The
installation of boilers under collective pressure flues is allowed exclusively
in G20.
The boiler is sized to operate correctly up to a maximum internal pressure
of the flue no higher than the value of 25 Pa. Check that the fan speed
corresponds to what is shown in the table "technical data".
Make sure that the air intake and exhaust pipes of the combustion products
are watertight.
WARNINGS:
b
The appliances connected to a collective pipe must all be of the same
type and have equivalent combustion characteristics.
b
The number of devices connected to a positive pressure collective
pipe is defined by the flue designer.
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 duct of 25 Pa in the condition
in which n-1 boilers work at maximum rated heat input and 1 boiler at the
minimum rated heat input allowed by the controls.
b
The minimum permissible pressure difference between the flue gas
outlet and the combustion air inlet is -200 Pa (including - 100 Pa of
wind pressure).
For both types of exhaust, further accessories are available (curves,
extensions, terminals, etc.) which make possible the flue gas exhaust
configurations foreseen in the boiler booklet.
b
The pipes must be installed in such a way as to avoid condensation
sticking which would prevent the correct evacuation of the combustion
products.
b
A data plate must be present at the connection point with the collective
flue pipe. The plate must include at least the following information:
- the collective flue is sized for boilers C(10) type
- the maximum permissible mass flow of the combustion products
in kg/h
- the dimensions of the connection to the common pipes
- a warning concerning the openings for the air outlet and the entry
of the combustion products of the collective pressure pipe; the-
se openings must be closed and their tightness must be checked
when the boiler is disconnected
- the name of the manufacturer of the collective smoke pipe or its
identification symbol.

b
The collective smoke pipe must be adequate for an overpressure of
at least 200 Pa.
b
The collective flue must not be equipped with a wind-proofing device.
At this point it is possible to install the curves and extensions, available as
accessories, depending on the type of installation desired.
The maximum permissible lengths of the flue pipe and the air intake pipe
are given in the instruction manual of the reference device (fig 18a-18b).
With C(10) installation, in any case, report the number of fan speed
(rpm) on the label placed next to the data plate.
Installation currently not available on model 40kW.
3.16 Filling the heating system and eliminating air
Note: When the air is being eliminated from the boiler using the deaeration
tap (A - fig. 19) the filling of the siphon occurs ("3.19 Condensate siphon");
make very sure that the level does not exceed the level shown in the figure,
if necessary closing the deaeration tap (A - fig. 19).
Note: the first filling operation must be carried out by turning the filling tap
(B - fig. 19) with the boiler OFF.
Note: each time the boiler is powered up, the automatic venting cycle is
carried out.
Note: the presence of a water alarm (40, 41 or 42) does not allow the
venting cycle to be carried out. The presence of a domestic hot water
request during the venting cycle interrupts the venting cycle.
Once the hydraulic connections have been made, fill the heating system
as follows:
- Set the boiler to OFF by pressing button 1
- Slowly open the de-aeration tap (A - fig. 19) and the system filling tap
(B - fig. 19)
- After about 1 minute, close the de-aeration tap (A - fig. 19)
- Wait for the pressure to increase: check that it reaches 1-1.5 bar; then
close the system filling tap (B - fig. 19).
Note: if the mains pressure is less than 1 bar, keep the system filling tap
(B - fig. 19) open during the venting cycle and close it once it has finished.
