Installation - Riello RESIDENCE KIS Series Installer And User Manual

INSTALLATION MANUAL
2 DESCRIPTION
The Residence KIS boilers have a new ACC combustion control system
(active combustion control).
This new control system, developed by Riello, in all circumstances provides
functionality, efficiency and low emissions.
The ACC system uses an ionisation sensor immersed in the burner flame,
whose information allows the control board to operate the gas valve that
regulates the fuel.
This sophisticated control system provides for the auto adjustment of the
combustion, thereby eliminating the need for an initial calibration
The ACC system can adapt the boiler to operate with different gas compositions,
different pipe lengths and various altitudes (within the design limits).
The ACC system can also perform an auto-diagnostic operation that locks
out the burner before the permitted upper emission limit is exceeded.
Residence KIS is a type C condensing wall-hung boiler to be used for
heating and the production of domestic hot water.
Depending on the fume discharge accessory used, it is classified in
categories B23P; B53P; C(10)*; C13,C13x; C33,C33x; C43,C43x;
C53,C53x; C83,C83x; C93,C93x.
* Currently not available on model 40kW.
In configuration B23P (when installed indoors), the appliance cannot
be installed in bedrooms, bathrooms, showers or where there are open
fireplaces without a proper air flow. The room where the boiler is installed
must have proper ventilation. Detailed requirements for the installation of
the flue, the gas piping and for ventilating the room, can be found in UNI
7129-7131.
In configuration C, the appliance can be installed in any type of room and
there are no limitations due to ventilation conditions or room volume.

INSTALLATION

3.1 Cleaning the system and characteristics of the water
In the case of a new installation or replacement of the boiler, it is necessary
to clean the heating system. To ensure the device works well, top up
the additives and/or chemical treatments (e.g. anti-freeze liquids, filming
agents, etc.) and check the parameters in the table are within the values
indicated.

3.3 Handling (Fig. 6)
After unpacking, handling of the boiler is done manually using the support
frame.
3.4 Installation room
The Residence KIS boiler can be installed in various types of room, as long
as the discharge of the combustion product and the combustion air suction
are outside the room itself.
In this case the room does not need any ventilation opening since the
Residence KIS boilers have a combustion circuit that is "airtight" with
respect to the installation environment.
b
Consider the clearances necessary to access safety and adjustment
devices and to perform maintenance operations.
b
Check that the electric protection level of the appliance is adapted to
the installation room characteristics.
b
If the boilers are supplied with fuel gas of a specific weight greater
than that of the air, the electric parts will have to be positioned more
than 500mm above ground level.

3.5 Installation on appliances that are old or that
need to be updated
When the Residence KIS boiler is installed in old systems or systems
being updated, check that:
- The flue is suitable for the temperature of the combustion products with
condensation, calculated and built according to Standard, is as straight
as possible, airtight, insulated and has no blockages or narrow sections.
It is equipped with appropriate condensate collection and discharge
systems
- The electrical system is installed in compliance with the specific standards
and by qualified personnel
- The fuel supply line and eventual tank (LPG) are made according to
specific Standards
- The expansion tank ensures the total absorption of the dilatation of the
fluid contained in the system
- The flow rate and head of the circulator are suitable to the characteristics
of the system
- The system is washed, cleansed of any mud, build-up, vented and
sealed. It is recommended that a magnetic filter be installed on the
system's return line
- The boiler condensate drain system (siphon) is connected and routed to
the collection of "white" water.
3.6 Installation regulations
The installation must be carried out by qualified personnel, in compliance
with the following reference standards:
- UNI 7129-7131
- CEI 64-8.
Always comply with local standards of the Fire Department, the Gas
Company and with possible municipal dispositions.
POSITION
Residence is a wall-hung boiler for heating and for the production of hot
water, that comes in two categories, depending on the type of installation:
- B23P-B53P boiler type - forced open installation, with flue gas discharge
pipe and pick-up of combustion air from the installation area. If the boiler
is not installed outdoors, air intake in the installation area is compulsory.
- C(10), C13,C13x; C33,C33x; C43,C43x; C53,C53x; C83,C83x, C93,C93x
boiler type: appliance with airtight chamber, with flue gas discharge pipe
and pick-up of combustion air from outside. It does not require an air
intake point in the installation area. This type MUST be installed using
concentric pipes, or other types of discharge designed for condensing
boilers with an airtight chamber.
Residence can be installed indoor and outdoor, in a partially protected place
(i.e. a place where the boiler is not exposed to direct contact or infiltration of
rain, snow or hail) and in compliance with local and national regulation. The
-
boiler can operate in a temperature range from >0°C to +60°C.
Residence 25 KIS can also be installed outdoor in the built-in unit.
ANTI-FREEZE SYSTEM
The boiler is fitted as standard with an automatic anti-freeze system that
-
activates when the temperature of the water in the primary circuit falls below
-
5°C. This system is always active and provides protection for the boiler up
to an air temperature in the installation area of 0°C.
b
To take advantage of this protection (based on burner operation),
the boiler must be able to switch itself on; any lockout condition
(for ex. due to a lack of gas or electrical supply, or the intervention
of a safety device) therefore deactivates the protection.
b
mm
When the boiler is installed in a place where there is a risk of
mm
freezing, with outside air temperatures below 0 °C, an antifreeze
heater kit must be used to protect the DHW circuit and conden-
mm
sation drain (available on request - see catalog) that protects the
mm
boiler up to -15 °C.
b
kg
The installation of the antifreeze heater kit must be carried out only
by authorized personnel, following the instructions contained in
the kit.
In normal operating conditions, the boiler can protect itself against frost.
If the machine is left without power for long periods in areas where
temperatures may fall below 0°C, and you do not want to drain the heating
system, you are advised to add a specific, good quality antifreeze liquid to the
primary circuit. Carefully follow the manufacturer's instructions with regards
not only the percentage of antifreeze liquid to be used for the minimum
temperature at which you want to keep the machine circuit, but also the
duration and disposal of the liquid itself.
For the hot domestic water part, we recommend you drain the circuit.
The boiler component materials are resistant to ethylene glycol based
antifreeze liquids.
MINIMUM DISTANCES (Fig. 8a-8b)
To ensure access to the boiler for normal maintenance operations, respect
the minimum installation clearances envisaged.
For correct appliance positioning, bear in mind that:
- it must not be placed above a cooker or other cooking device
- it is forbidden to leave inflammable products in the room where the boiler
is installed
- heat-sensitive walls (e.g. wooden walls) must be protected with proper
insulation.
