"Airtight" Installation (Type C) - Riello Start Aqua Condens 25/60 BIS Installer And User Manual

9
Mandatory items:
- use an omnipolar
disconnector, compliant with CEI-EN 60335-1 standards
(contact opening of at least 3.5mm, category 3)
- use cables with a section ≥ 1.5mm
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
0
It is forbidden to use gas and water pipes for grounding the
unit.
9
The manufacturer is not liable for any damage caused by
failure to comply with the wiring diagrams.
9
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.
3.11 Boiler configuration
The electronic board has a number of jumpers (JPX) that allow to
configure the boiler.
To access the board, proceed as follows:
- set the main system switch to OFF
- loosen the screws (B) that hold the housing in place (fig. 12)
- move the base of the shell forward and then upwards in order to
free it from the frame (fig. 13)
- turn the instrument panel forward
- unscrew the two screws of the small cover on the electronic
board to have access to the terminals (fig. 14).
JUMPER JP7: pre-selection of the most appropriate heating
temperature adjustment field based on the type of system.
Jumper not inserted - standard system: standard system 40-80 °C
Jumper inserted - floor system: floor installation 20-45°C.
During manufacture, the boiler is configured for standard systems
(fig. 15).

3.12 Gas connection
The connection of the Start Aqua Condens 25/60 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.
9
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.
9
Once the installation is done, check that the junctions carried
out are sealed.

3.13 Flue gas outlet and combustion air suction (fig. 16-17-
feeder 18-19-20)
The Start Aqua Condens 25/60 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.
9
For the maximum lengths of the ducts refer to flue systems
available in the catalogue.
(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.
9
In this case, the combustion air is picked up from the boiler
installation room (which must be a suitable technical room
with proper ventilation).
9
The non insulated flue gas outlet pipes are potential sources
of danger.
9
Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.
maximum length of the flue gas
discharge pipe ø 80mm
9
"Straight length" means without bends, drainage terminals or
joints.

"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)
The concentric pipes can be fitted in most suitable direction in
relation to installation requirements.
9
It is compulsory to use specific pipes (see Riello catalogue).
9
Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.
9
Non-insulated outlet pipes are potential sources of danger.
9
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.
HORIZONTAL

pipe Ø 60-100 mm
VERTICAL
straight length of concentric
pipe Ø 60-100 mm
For installation, follow the instructions supplied with the specific
accessory kit for condensing boilers.
9
Straight length means without bends, drainage terminals or
joints.
9
The use of a longer pipe causes a loss of output of the boiler.
