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 boiler must be installed by a qualified 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
producer, for which it was expressly made. No contractual
or extracontractual liability is accepted by Riello for damage
caused to people, animals, or objects due to errors in installation,
adjustment, 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
professionally qualified technician.
Check regularly that the hydraulic system operating pressure
is between 1 and 1.5 bar. If the pressure is not between these
values, fill the system as indicated in the specific chapter. In the
event of frequent pressure drops, please seek assistance from
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 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 accompany
the boiler, even if it is sold to another owner or user, or transferred
to another facility. If lost or damaged, please request another copy
from the Technical Assistance Service for your area.
The boilers are designed to protect both the user and 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.
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 correctcombustion and for safety
(only KI model).
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 switches
or domestic appliances, etc. if you can smell gas or unburned gas.
Should this occur:
- open the doors and windows to ventilate the room
- close the gas shut-off device
- call 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 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 electricity
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
material out of the reach of children, as this is a potential source
of danger.
2 - DESCRIPTION
START
is a wall-mounted gas boiler for central heating and domestic
hot water, with a monothermal exchanger.
The boiler is controlled electronically with automatic ignition, ionisation
flame control, modulati
ng in heating and DHW mode.
START KI:
it is fitted with an open combustion chamber and classed
in category B
11BS
.
START KIS:
has a sealed combustion chamber and, based on the
gas discharge accessory used, is classified in
B22P,B52P; C12,C12x;
C22 (where required); C32,C32x; C42,C42x; C52,C52x; C82,C82x;
C92,C92x categories.
To guarantee the correct water flow in the exchanger, the boiler is fitted
with an automatic bypass device.
It is also complete with the safety, expansion and distribution
accessories.
START
boiler is fitted with:
- microprocessor control and management with self-diagnostics
- pump anti-block function and 3-way valve
-
first level anti-freeze (suitable for indoor installations)
- provision for room thermostat or timer or zone valve
- digital display indicating operating temperature and fault codes.
2.1
Safety devices
START
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.
-
START KI: Fumes thermostat
, which intervenes setting the boiler
to safety stop status if combustion products return in the hood. It is
located on the right tile of the draught diverter mechanism.
-
START KIS: Differential air pressure switch,
which intervenes by
placing the boiler in a state of security stop in case of faults in the
fume exhaust circuit.
If a safety device is tripped, there is a boiler fault. Please contact
the Technical Assistance Service immediately.
The
fumes thermostat
and the
differential air pressure switch
are tripped not only by a defect in the combustion product evacuation
circuit, but also by random atmospheric conditions.
Therefore, after a short wait, the boiler can be restarted (see the
chapter “First start-up”).
START KI:
If the fumes thermostat trips repeatedly, this
means combustion products are evacuated towards the boiler
installation area. This means combustion may be incomplete
and there is a risk of carbon monoxide forming. This is a serious
hazard. In this case, please contact the Technical Assistance
Service immediately.
