INSTALLER MANUAL
1 - WARNINGS AND SAFETY INSTRUCTIONS
After removing the packaging, make sure that the product is
integral and complete with all its parts. If it does not correspond
with the order made, please contact the Riello Agency that sold
the boiler.
The START AQUA 24 BI boiler must be installed by a quali-
fied company in accordance with the regulations in force and
in observance of applicable legislation and of the indications
provided by Riello in the present instructions booklet.
The installer explains how the appliance operates to the user,
and the basic safety regulations.
The boiler must be used for the purpose envisaged by the pro-
ducer, for which it was expressly made. No contractual or ex-
tracontractual liability is accepted by Riello for damage caused
to people, animals, or objects due to errors in installation, ad-
justment, or maintenance or by improper use.
In the event of a water leak, shut-off the water supply and
promptly notify the Technical Assistance Service or a profes-
sionally qualified technician.
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.
Periodically check that the icon does not light up on the dis-
play. This icon indicates an incorrect filling pressure value. If
this icon lights up, please see "Smart system filling".
If the boiler will not be used for a prolonged period of time, you
must:
- turn the main switch of the device and the general 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.
Boiler maintenance must be carried out at least once a year.
This manual and the user manual are an integral part of the
device. They must be carefully preserved and must always ac-
company the boiler, even if it is sold to another owner or user,
or transferred to another facility. If lost or damaged, please re-
quest another copy from the Technical Assistance Service for
your area.
The boiler is designed to protect both the user and the installer
from any accidents. After any intervention on the product, take
care to restore the electrical connections. Take special care
with stripped sections of wire, which must never protrude from
the terminal board.
Dispose of packaging materials in the relevant containers at
authorised waste collection centres.
Waste must be disposed of without any risk to personal health
and safety and without adopting procedures or methods that
may be harmful to the environment.
The air vents are essential for correct combustion.
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 devices or electrical 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 appliance 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 modify the safety or adjustment devices without prior
authorisation or instructions from the boiler manufacturer.
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.
Dispose of packaging responsibly and keep all packaging ma-
terial out of the reach of children, as this is a potential source of
danger.
2 - DESCRIPTION
START AQUA 24 BI is a wall-mounted gas boiler for central heating
and domestic hot water, equipped with a 45-litre water tank.
The boiler is controlled electronically with automatic ignition, ionisa-
tion flame control (with a single electrode), modulating in heating and
DHW mode.
It has a B
11BS
open combustion chamber.
Switch between heating and DHW mode using an electric 3-way
valve, which is set to heating mode when in standby. To guarantee
the correct water flow in the primary exchanger, the boiler is fitted
with an automatic bypass device.
It is also complete with the safety, expansion and distribution acces-
sories.
The boiler is fitted with an efficient microprocessor control system.
START AQUA 24 BI boilers are also fitted with:
- Pump anti-block function and 3-way valve
- First level anti-freeze (suitable for indoor installations)
- Gas valve complete with stabiliser and slow ignition
- Provision for room thermostat or timer (to be installed outside the
boiler)
- Provision for DHW timer (to be installed outside the boiler)
- Baby Safety function: this function, with jumper JP1 wired in, al-
lows the domestic water storage temperature to be automatically
set at 43 +- 3 °C (electronically disabling the temperature selection
dial). This prevents the risk of scalding if the domestic hot water
tap is turned out inadvertently. Activating this function prevents use
of the anti-legionella function. This function can be activated on
request by contacting the Technical Assistance Service.
- Anti-legionella function: Legionella is a disease that can be caught by
inhaling small droplets of water (aerosol) that contain the legionella
bacteria (this is found naturally in lakes and rivers throughout the world).
The bacteria is eliminated by bringing the stored water to a tem-
perature exceeding 50°C/55°C. It is therefore recommended that
the DHW temperature selection knob be set to the maximum value
at least every 2/3 days to bring the water temperature to 63°C,
maintaining this temperature for at least 5 minutes.
2.1 Safety devices
The START AQUA 24 BI boiler is equipped with the following safety
devices:
- Safety valve and water pressure switch, which intervene in the
event of insufficient or excessive water pressure (min. 0.7 bar -
max. 3 bar).
- Water temperature limit thermostat, which intervenes setting the
boiler to safety stop status if the temperature exceeds the values
envisaged by current standards.
