and comply with the
connection L (phase) - N (Neutral)
- the switch amperage must be adapted to the electric output
of the boiler, refer to technical data to check the electric
output of the model installed
- connect the appliance to an effective grounding system
- safeguard access to the power socket after the installation
It is forbidden to use gas and water pipes for grounding the
unit.
The manufacturer is not liable for any damage caused by
failure to comply with the wiring diagrams.
The installer is responsible for ensuring the appliance is
suitably earthed; the manufacturer will not be liable for any
damage resulting from an incorrect or absent earth connection.
3.10 Gas connection
The connection of the
Family Aqua Condens 3.5 BIS
boiler to the
gas supply must be carried out in compliance with current installation
standards.
Before carrying out the connection, it is necessary to ensure that:
- the gas type is suitable for the appliance
- the piping is thoroughly clean.
The gas feeding system must be adapted to the boiler output
and must be equipped with all the safety and control devices
prescribed by the current standards. the use of a filter of
adequate dimensions is recommended.
Once the installation is done, check that the junctions carried
out are sealed.
3.11 Flue gas outlet and combustion air suction
The
Family Aqua Condens 3.5 BIS
boiler must be equipped with
adequate flue gas outlet and air suction pipes according to the
type of installation, to be chosen from those indicated in the Riello
catalogue.
The maximum lengths of the ducts refer to flue systems availa-
ble in the catalogue.
The straight length measurement is inclusive of the first bend
(boiler connection), terminals and joints; with the exception
of the vertical coaxial duct Ø 60-100 mm, where the straight
length does not include the bends.
(TYPE B23P-B53P) INSTALLATION
Flue gas discharge pipe ø 80mm
The flue gas outlet pipe can be directed to the most suitable direction
according to installation requirements.
For installation, follow the instructions supplied with the kit.
In this configuration, the boiler is connected to the flue gas outlet pipe
of ø 80 mm through an adaptor of ø 60-80 mm (fig. 7).
In this case, the combustion air is picked up from the boiler
installation room (which must be a suitable technical room with
proper ventilation).
The non insulated flue gas outlet pipes are potential sources of
danger.
Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.

“AIRTIGHT” INSTALLATION (TYPE C)
The boiler must be connected to concentric or twin flue gas discharge
pipes and air suction pipes, both leading outdoors. The boiler must
not be operated without them.
Concentric pipes (ø 60-100mm, fig. 8)
The concentric pipes can be fitted in most suitable direction in relation
to installation requirements.
It is compulsory to use specific pipes (see Riello catalogue).
Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.
Non-insulated outlet pipes are potential sources of danger.
The boiler automatically adapts ventilation according to the
type of installation and the length of the duct. Do not obstruct
or choke the combustion air suction pipe in any way.

The appropriate adaptor kit must be installed for this configuration.
The concentric pipes can be fitted in most suitable direction in relation
to installation requirements. For installation, follow the instructions
supplied with the specific kit for condensing boilers.

Twin pipes (ø 80 mm) (fig. 9)
The twin pipes can face in the direction most suited to the installation
requirements.
The suction pipe of the combustion air must be connected to the
input after removing the cap fixed with three screws.
The flue gases discharge pipe must be connected to the flue gases
outlet.
For installation, follow the instructions supplied with the specific
accessory kit for condensing boilers.

The use of a longer pipe causes a loss of output of the boiler.
It is compulsory to use specific pipes (see Riello catalogue).
Make sure the flue gas discharge pipe is tilted 3° 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.
For the indication of the maximum lengths of the single pipe,
refer to the chart (fig. 18).
