water begins to drain out of the valve.
3. Switch on the electricity supply to the boiler, leaving the gas tap turned off.
4. Activate a heat request via the room thermostat or the remote control
panel, so that the 3-way valve goes into heating mode.
5. Activate a DHW request as follows:
instantaneous boilers: open a tap, for 30 seconds every minute so
that the three-way valve switches from heating to domestic hot water
and vice versa about ten times. In this situation, the boiler will go into
alarm mode due to the absence of gas, so it must be reset every time
this happens.
heat-only boilers connected to an external storage tank: activate the
thermostat on the storage tank;
6. Carry on with the sequence until only water leaks out of the manual air
vent valve, and the air fl ow has stopped. Close the manual air vent valve.
7. Check the system pressure level is correct (the ideal level is 1 bar).
8. Turn off the system fi lling tap.
9. Turn on the gas tap and ignite the boiler.
3.12 Flue gas discharge and air suction
Observe local legislation regarding fl ue gas discharge.
Flue gases are discharged
from a centrifugal fan located inside the combus-
tion chamber and the
control board
constantly checks that this is working
correctly. The boiler is supplied without the fl ue gas discharge/air suction kit,
since it is possible to use the accessories for appliance with a forced draught
sealed chamber that better adapts to the installation characteristics. For fl ue
gas extraction and the restoration of boiler combustion air, it is essential to
only use certifi ed piping. Connection must be carried out correctly as indicated
in the instructions supplied as standard with the fl ue gas
accessories.
Multiple appliances can be connected to a single smoke pipe provided that
each is a sealed chamber-type appliance. The boiler is a Type C appliance
(sealed chamber), and must therefore have a safe connection to the fl ue
gas discharge pipe and to the combustion air suction pipe; these both carry
their contents outside, and are essential for the operation of the appliance.
POSSIBLE OUTLET CONFIGURATIONS (FIG. 24)
B23P/B53P
Suction indoors and discharge outdoors
C13-C13x Discharge via concentric wall outlet. The pipes may leave the
boiler independently, but the outlets must be concentric or suffi ciently close
together to be subjected to similar wind conditions (within 50 cm)
C23 Discharge via concentric outlet in common smoke pipe (suction and
discharge in the same pipe)
C33-C33x Discharge via concentric roof outlet. Outlets as for C13
C43-C43x Discharge and suction in common separate smoke pipes, but
subjected to similar wind conditions
C53-C53x Separate discharge and suction lines on wall or roof and in areas
with different pressures. The discharge and suction lines must never be
positioned on opposite walls
C63-C63x Discharge and suction lines using pipes marketed and certifi ed
separately (1856/1)
C83-C83x Discharge via single or common smoke pipe and wall suction line
C93-C93x Discharge on roof (similar to C33) and air suction from a single
existing smoke pipe
“FORCED OPEN” INSTALLATION (TYPE B23P/B53P)
Flue gas discharge pipe ø 80 mm (fi g. 20)
The fl ue gas discharge pipe can be directed to the most suitable direction
according to installation requirements. For installation, follow the instruc-
tions supplied with the kit. In this confi guration, the boiler is connected to
the fl ue gas discharge pipe (ø 80 mm) through an adaptor (ø 60-80 mm).
The B23P/B53P confi guration is forbitten in case of installation in
pressurised collective chimney (3CEp).
In this case, the combustion air is picked up from the boiler instal-
lation room (which must be a suitable technical room with proper
ventilation).
Uninsulated fl ue discharge outlet pipes are potential sources of danger.
Arrange the fl ue gas discharge pipe so it slopes by 1% towards the boiler.
The boiler automatically adapts the purging to the type of installation
and the length of the pipe.

“SEALED” INSTALLATION (TYPE C)
The boiler must be connected to concentric or twin fl ue gas discharge pipes
and air suction pipes, both leading outdoors. The boiler must not be oper-
ated without them.
Concentric pipes (ø 60-100 mm) (fi g.21)
The concentric pipes can be placed in the most suitable direction according
to installation requirements, complying with the maximum lengths indicated
in the table.
Arrange the fl ue gas discharge pipe so it slopes by 1% towards the
boiler.
Non-insulated outlet pipes are potential sources of danger.
The boiler automatically adapts the purging to the type of installation
and the length of the pipe.
Do not obstruct or choke the combustion air suction pipe in any way.
For installation, follow the instructions supplied with the kit.

If the boiler must be installed with drainage below, use the special elbow (kit
available on request – see Parts Catalogue).
In this type of installation, the inner pipe of the elbow must be cut at the
point shown in fi g. 22 to allow the elbow itself to be inserted more easily into
the fl ue gas discharge on the boiler.
Concentric pipes (ø 80-125)
For this confi guration, the special adaptor kit must be fi tted. The concentric
pipes can face in the direction most suitable for installation requirements.
For installation, follow the instructions supplied with the specifi c condensing
boilers kits.

Twin pipes (ø 80 mm) (fi g. 23)
The twin pipes can face in the direction most suited to the installation re-
quirements. For installation, follow the instructions supplied with the spe-
cifi c accessory kit for condensing boilers.
To use the combustion air suction pipe, one of the two inlets (A and B) must
be selected. Remove the closure plug which is fi xed using screws, and use
the specifi c adaptor relating to the inlet selected (C air inlet adaptor ø 80 - D
air inlet adaptor from ø 60 to ø 80) available as an accessory.
Arrange the fl ue gas discharge pipe so it slopes by 1% towards the
boiler.
The boiler automatically adapts the purging to the type of installation
and the length of the pipes. Do not obstruct or choke the pipes in
any way.
Refer to the graphs to fi nd the maximum lengths of the single pipe.
The use of longer pipes reduces the boiler output.
