(*) Length that can be installed with pipes in class P11.
The Ø 50 and Ø 60 configurations use test data obtained in the lab-
oratory.
In the event of installations that differ from the indications in the
“standard configurations” and “adjustments” tables, refer to the
equivalent linear lengths below (fig. 27).
In any case, the maximum lengths declared in the booklet are
guaranteed, and it is essential not to exceed them.

3.12 System loading and emptying (fig.28)
Once the hydraulic connections have been carried out, fill the sys-
tem.
LOADING
- Open the caps of the lower automatic air vent valves (A) and upper
(E) by two or three turns; to allow a continuous venting of the air,
leave the plugs of valves A and E.
- Make sure the cold water inlet tap is open, turning it anti-clockwise.
- Open the filling tap (B) until the pressure indicated by the water
pressure gauge is between 1 and 1.5 bar.
- Close the filling tap (B).
NOTE: the venting of the FAMILY CONDENS IS E boiler takes place
automatically via the two automatic bleed valves A and E, the first
positioned on the circulator and the second inside the air distribution
box.
EMPTYING
- Before starting emptying, switch off the electrical supply by turning
off the system's main switch
- Close the cold water inlet tap
- Close the shut-off devices of the heating system
- Manually loosen the system drain valve (B)
- The water is discharged through the discharge manifold (C) - for
details refer to paragraph "Discharge manifold".
The discharge manifold (C) must be connected via a pipe not
provided) to an appropriate collection and evacuation system
in the white water discharge drain in compliance with current
regulations. The manufacturer is not liable for any damage re-
sulting from the failure to channel the condensate.
3.13 Installation of collective positive pressure smoke pipes
The collective smoke pipe is a flue gases system suitable for col-
lecting and expelling combustion products of several appliances in-
stalled on different floors of a building (fig. 29).
The collective flues in positive pressure can be used only for type C
condensing appliances. Consequently the B53P/B23P configuration
is not permitted.
Installation of the boiler on collective flues in pressure is permitted
using a specific check valve, supplied as an accessory. See the re-
lated instructions for the assembly procedure.
The boiler is sized to operate correctly up to a maximum internal
pressure of the smoke pipe no higher than the value shown in the
multigas table (fig. 30).
Complete the check valve assembly operations and proceed with
adjustment of the number of fan rotations as shown in the multigas
table.
Make sure that the air suction and combustion fumes discharge
pipes are sealed.
The installation of the check valve requires the application of the
CAUTION label, supplied with the accessory, on a visible part of the
boiler casing. The application of the label is essential for safety pur-
poses during the maintenance or replacement of the boiler and/or
collective smoke pipes.
WARNINGS
The manufacturer assumes no liability if the check valve and
related label is not installed before the commissioning of the
boiler.
Appliances connected to a collective smoke pipe must all be of
the same type and have equivalent combustion characteristics.
The number of appliances that can be connected to a collective
positive pressure smoke pipe is defined by the designer of the
smoke stack.
MAINTENANCE FOR APPLICATION IN A COLLECTIVE PRES-
SURIZED SMOKE PIPE
During scheduled maintenance on the appliance you must also
check the condition of the check valve in order to guarantee correct
operation and safety of the system.
Before proceeding with maintenance you must conduct an analysis
of the combustion product and check the boiler operating status.
If performing maintenance to the combustion circuit of the boil-
er (flue gas pipes, heat exchanger, condensate trap, burner,
electrode conveyors, fan) it is necessary to ensure the closure
of the flue gases pipe coming from the pressurised smoke pipe
and check for leaks.
Then:
- Switch off the electrical supply by setting the system's main switch
to "off"
- Close the gas shut-off valve
- Remove the housing
- Unhook the instrument panel and rotate it downward
- Unhook and remove the air box cover
- After undoing the related fixing screws, remove the right side of
the air box,
- Undo the nut that secures the gas train valve to the air box
