General instructions

This manual and the Installer and Technical Assistance Service
manual are an integral part of the boiler. They must be carefully
preserved and must always accompany the boiler, even if sold
to another owner or user, or transferred to another facility. If
lost or damaged, please request another copy from the Riello
Technical Assistance Service for your area.
The START AQUA 24 BI boiler must be installed by a qualified
company. Once the appliance has been installed, this company
must issue an installation declaration of conformity, certifying
that the installation has been performed professionally, in com-
pliance with all national and local regulations in force, and with
the Riello instruction manual supplied with the appliance.
The START AQUA 24 BI boiler must be used for the purpose
for which it was designed and produced by the manufacturer.
Riello does not accept any contractual or extra-contractual li-
ability for damage caused to people, animals or property, due
to incorrect installation, setting, or maintenance, or due to im-
proper use.
In the event of a water leak, disconnect the boiler from the elec-
tric mains supply, shut-off the water supply and promptly notify
the Technical Assistance Service or a professionally qualified
technician.
Periodically check that the operating pressure of the water sup-
ply system is above 1 bar and below the maximum limit speci-
fied for the appliance. If this is not the case, please contact
the Technical Assistance Service or a professionally qualified
technician.
If the boiler will not be used for a prolonged period of time, you
must:
- turn the main appliance switch to "OFF"
- turn the main system switch to "OFF"
- shut off the heating system gas and water cocks
- empty the heating system and the domestic hot water (DHW)
system if there is a risk of freezing.
The pump anti-block function is activated after 24 hours of in-
activity, with the function selector on any setting.
For installation of this device, contact specialised personnel for
assistance.
At the end of its lifetime, the product must not be disposed of as
solid urban waste but must be delivered to a specialised waste
disposal centre for recycling.
The air vents are essential for correct combustion and for safety.
B - Basic safety rules
Please remember that in using products which involve gas, electricity
and water, you must adhere to some basic safety requirements:
Children and unassisted disabled persons must not use the
boiler.
Do not operate electrical devices or appliances such as switch-
es or domestic appliances, etc. if you can smell gas or un-
burned gas. Should this occur:
- open the doors and windows to ventilate the room;
- close the gas shut-off device;
- contact the Technical Assistance service or a professionally
qualified technician immediately.
Do not touch the boiler when barefoot or with any wet parts of
the body.
Do not clean the boiler without having disconnected it from the
mains power supply by setting the power switch to "off".
Do not pull, disconnect or twist the electrical cables coming
from the boiler, even if it is disconnected from the mains elec-
tricity supply.
Do not seal off or reduce the size of the air vents (if present) in
the room where the boiler is installed.
Do not leave containers of flammable substances in the room
where the boiler is installed.
Do not place potentially hazardous objects on the boiler.
Do not disconnect the boiler from the electrical mains or shut
off the gas valve if the temperature could fall below zero, as the
first level anti-freeze system (protection up to -3°C) would be
disabled.
Do not modify sealed components.
Flue safety device: the boiler is equipped with a control system
to ensure combustion products are evacuated correctly. In the
event of a fault, this device sends the boiler into safety lockout.
To return to normal operating conditions, turn the function se-
lector to "OFF". If the fault persists, call a qualified technician
from the Technical Assistance Service. The control device to
ensure correct flue evacuation must not be disabled under any
circumstances. If the device or any faulty components are re-
placed, use original spare parts only.
At the end of its lifetime, the product must not be disposed of as
solid urban waste but must be delivered to a specialised waste
disposal centre for recycling.
C - Commissioning
The boiler should be started up the first time by the Technical As-
sistance Service, after which the device can operate automatically.
However, you may need to start up the boiler again at a later date
without involving the Technical Service, for example after a long pe-
riod of absence.
In these cases:
- Ensure that the heating and domestic hot water system gas and
water cocks are open.
- Check the operating status of the filtering and/or water treatment
devices.
- Ensure that the water circuit pressure, in cold conditions, is always
between 1 and 1.5 bar.
- Adjust the room thermostat to the required temperature (~20°C) or,
if the systems are equipped with a programmable thermostat or a
timer, check that it is ON and set (~20°C).
- Turn the function selector to the required setting:
Winter mode
When the function selector is set to within this range, the boiler sup-
plies domestic hot water and heating. In the event of a heating re-
quest, the boiler turns on.
WINTER FUNCTION
The digital display indicates the heating water temperature. In the
event of a DHW request, the boiler turns on. The display indicates
the temperature of the domestic hot water.
