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, efciency and low emissions.
The ACC system uses an ionisation sensor immersed in the burner ame,
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
TheACC 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 classied 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 conguration B23P (when installed indoors), the appliance cannot
be installed in bedrooms, bathrooms, showers or where there are open
replaces without a proper air ow. The room where the boiler is installed
must have proper ventilation. Detailed requirements for the installation of
the ue, the gas piping and for ventilating the room, can be found in UNI
7129-7131.
In conguration C, the appliance can be installed in any type of room and
there are no limitations due to ventilation conditions or room volume.
3 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, lming
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 specic 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 ue 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 specic standards
and by qualied personnel
- The fuel supply line and eventual tank (LPG) are made according to
specic Standards
- The expansion tank ensures the total absorption of the dilatation of the
uid contained in the system
- The ow 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 lter 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 qualied 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 ue 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 ue 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 inltration 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 tted 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 When the boiler is installed in a place where there is a risk of
freezing, with outside air temperatures below 0 °C, an antifreeze
heater kit must be used to protect the DHW circuit and conden-
sation drain (available on request - see catalog) that protects the
boiler up to -15 °C.
b
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 specic, 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 inammable products in the room where the boiler
is installed
- heat-sensitive walls (e.g. wooden walls) must be protected with proper
insulation.

RESIDENCE
b When installing it is ABSOLUTELY NECESSARY to provide the
spaces necessary for the introduction of the instrument for analysing
the combustion. We have provided a sample diagram where the
distances between the boiler and wall unit /recess have been
obtained using an instrument with a length of 300 mm. Longer
instruments require more space.
3.7 Installation of condensate drain pipe (Fig. 9)
b Before starting the boiler, even just temporarily, the SRD device
supplied must be installed.The manufacturer does NOT accept
liability for damage to persons or objects caused by the boiler
operating without the SRD device being installed correctly.
For the installation proceed as follows:
- remove the plug (T) from the siphon
- x the SRD device to the siphon, placing the gasket in-between, screwing
it on all the way and checking its seal
- connect the condensate discharge pipe supplied as standard with the
product, then drain the condensate into a suitable drainage system in
compliance with current norms.
b If it is not possible to t the SRD device due to the interference
with other objects under the boiler, it is possible to t it in a different
position by inserting a connecting pipe between the SRD device and
the siphon in order to provide a fully airtight seal. The SRD device
should always be positioned VERTICALLY in order to ensure it
functions correctly
3.8 Positioning the wall-mounted boiler and hydraulic
connections (Fig. 10)
The boiler comes as standard with a boiler support plate. The position and
dimension of hydraulic ttings are shown in the detail drawing.
For the assembly, proceed as follows:
- fasten the boiler support plate (F) to the wall and use a spirit level to
make sure it is perfectly horizontal
- mark the 4 holes (ø 6 mm) envisaged for securing the boiler support
plate (F)
- make sure that all measurements are exact, then drill the wall using drill
tips with the diameters indicated above
- x the plate with the built-in template (G) to the wall.
- x the safety valve pipe supplied in the documentation envelope onto the
coupling of the safety valve (S), then connect it to an adequate discharge
system.
Make the hydraulic connections:

OTBus remote control connection
When an OTBus remote control is connected to the system
, the boiler display
shows the following screen:
In particular on the boiler display:
it is no longer possible to set the boiler OFF/WINTER/SUMMER status
(it is set by the OTBus remote control)
it is no longer possible to set the domestic hot water setpoint (it is set by
the OTBus remote control)
it is not possible to activate the COMBUSTION CONTROL function if the
boiler is connected to a remote OTBus
In addition:
The domestic hot water setpoint is displayed in the INFO menu
The combination of the A+Bkeys remains active for the setting of the
DOMESTIC HOT WATER COMFORT function.
The heating setpoint set on the boiler display is used only if there are
heat requests from the TA and the OTBus remote control does not have
a request if the parameter DO_AUX1 = 1 or DO_AUX1 = 0 and the
jumper on 1-2pin of X21 is closed.
We can see that it is not possible, with the OTBus remote control connected,
to change the values of the parameter MAIN ZONE ACTUATION TYPE and
ZONE1 ENABLE to 1.
Note: an OT+ remote control cannot be connected if the system al-
ready has BE16 interface boards. For the same reason it is not pos-
sible to connect BE16 boards if there is already an OT+ device.
In this case the system gives the following error message:
<<OT+ CONFIGURATION ERROR>>.
High voltage connections
The connection to the mains supply must be made via a separation device
with an omnipolar opening of at least 3.5 mm (EN 60335/1 - category 3).
The appliance works with alternating current at 230 Volt/50 Hz, and is in
compliance with Standard EN 60335-1.
It is obligatory to make the connection with a safe ground/earth, in
compliance with current directives.

ENGLISH
b 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
b It is also advisable to respect the phase-neutral connection (L-N).
b The earth conductor must be a couple of cm longer than the others.
b To create the seal of the boiler use a clamp and tighten it on the cable
grommet used.
The boiler can operate with a phase-neutral or phase-phase (not oating)
power supply.
It is forbidden to use gas and/or water pipes to earth electrical appliances.
Use the power cable supplied to connect the boiler to the mains power
supply. If the power cable has to be replaced, use a HAR H05V2V2-F, 3 x
0.75mm² cable, Ø max external 7 mm.
3.10 Gas connection
The connection of the gas supply must be carried out in compliance with
current installation standards. Before carrying out the connection, check
that the type of gas is that for which the appliance is set up.
3.11 Variable speed circulator
The modulating circulator function is active only in the heating function.
In the switching of the three-way on the domestic hot water, the circulator
always operates at maximum speed. The modulating circulator function
applies
only to the boiler circulator and not to circulators of any external devices
that are connected (e.g. relaunch circulator).
There are 4 management modes to choose from depending on the situations
and the type of system.
Entering the CH menu, parameter PUMP CONTROL TYPE, it is possible to
choose from:
1 - VARIABLE SPEED CIRCULATOR WITH PROPORTIONAL MODE
(41 <= PUMP CONTROL TYPE <= 100)
2 - VARIABLE SPEED CIRCULATOR WITH CONSTANT ∆T MODE
(2 <= PUMP CONTROL TYPE <= 40)
3 - CIRCULATO
R IN FIXED MAXIMUM SPEED MODE
(
PUMP CONTROL TYPE = 1
)
4 - EXCEPTIONAL USE OF A STANDARD CIRCULATOR WHOSE SPEED
CANNOT BE REGULATED (PUMP CONTROL TYPE = 0)
1 - VARIABLE SPEED CIRCULATOR WITH PROPORTIONAL MODE (41 <=
PUMP CONTROL TYPE <= 100)
In this mode the boiler board determines which ow curve to be adopted for the
instantaneous output of the boiler .
2 - VARIABLE SPEED CIRCULATOR WITH CONSTANT ∆T MODE (2 <=
PUMP CONTROL TYPE<= 40)
In this mode the installer sets the ∆T value to be kept between delivery and
return (e.g.: entering a value= 10 la the speed of the circulator will change
to have a system ow rate with the aim of keeping the ∆T upstream and
downstream heat exchanger of 10°C).
3 - VARIABLE SPEED CIRCULATOR WITH FIXED MAXIMUM SPEED
MODE (PUMP CONTROL TYPE = 1)
In this mode the circulator, when activated, always operates at maximum speed.
Used in high pressure drop systems where it is necessary to fully exploit the
boiler discharge head in order to provide sufcient circulation (system ow at
maximum speed lower than 600 litres/hour).
Used when there are bottles of mixture with high ow rate in the downstream
circuit.
Operationally:
Enter parameter PUMP CONTROL TYPE
Set the value = 1
4 - EXCEPTIONAL USE OF A STANDARD CIRCULATOR WHOSE SPEED
CANNOT BE REGULATED (PUMP CONTROL TYPE = 0)
This mode should be used in exceptional cases where you want use a traditional
UPS circulator in the boiler.

3.12 Manual reset of the circulator
The circulator has an electronic reset function, however if a manual reset is
necessary, proceed as follows:
- use a Phillips screwdriver, preferably Phillips no. 2
- insert the screwdriver in the hole until it comes into contact with the reset
screw, then press (basically the screw should go in by about 2 mm) and turn
anti-clockwise.
3.13 Removing the casing
To access the components inside, remove the casing as indicated below:
- nd and unscrew the 2 screws (A - g. 11) xing the casing to the boiler
levering the two xing clips (C - g. 11), detach the bottom part of the
casing
- lift the casing upwards to release it from the top tabs (B - g. 11), then
remove it.
WARNING
b
If removing the side panels, put them back in their initial position,
referring to the adhesive labels on their walls.
b
If the front panel is damaged it must be replaced.
b
The noise absorbing panels inside the front and side walls ensure the
airtight seal for the air supply duct in the installation environment.
b
It is therefore CRUCIAL after the dismantling operations to correctly
reposition the components to ensure the boiler's seal is effective.
3.14 Flue gas exhaust and combustion air suction (Fig. 12)
To evacuate the combustion products, refer to UNI 7129-7131. Always
comply with local standards of the Fire Department, the Gas Company and
with possible municipal dispositions.
The evacuation of the combustion products is carried out by a centrifugal
fan and the control board constantly monitors that it is operating correctly.
It is essential for the evacuation of the ue gases and the adduction of the
boiler's combustion air that only original pipes be used (except C6) and that
the connection is made correctly as shown in the instructions provided with
the ue gases accessories.
A single ue can be connected to several appliances provided that every
appliance is the condensing type.
The boiler is a C-type appliance (with airtight chamber), and must therefore
have a safe connection to the ue gas discharge pipe and to the combustion
air suction pipe; these both carry their contents outside, and are essential
for the operation of the appliance.
Both concentric and twin terminals are available.

3.16 Filling the heating system and eliminating air
Note: When the air is being eliminated from the boiler using the deaeration
tap (A - g. 19) the lling of the siphon occurs ("3.19 Condensate siphon");
make very sure that the level does not exceed the level shown in the gure,
if necessary closing the deaeration tap (A - g. 19).
Note: the rst lling operation must be carried out by turning the lling tap
(B - g. 19) with the boiler OFF.
Note: each time the boiler is powered up, the automatic venting cycle is
carried out.
Note: the presence of a water alarm (40, 41 or 42) does not allow the
venting cycle to be carried out. The presence of a domestic hot water
request during the venting cycle interrupts the venting cycle.
Once the hydraulic connections have been made, ll the heating system
as follows:
- Set the boiler to OFF by pressing button 1
- Slowly open the de-aeration tap (A - g. 19) and the system lling tap
(B - g. 19)
- After about 1 minute, close the de-aeration tap (A - g. 19)
- Wait for the pressure to increase: check that it reaches 1-1.5 bar; then
close the system lling tap (B - g. 19).
Note: if the mains pressure is less than 1 bar, keep the system lling tap
(B - g. 19) open during the venting cycle and close it once it has nished.

3.15 Installation on collective ues in positive
pressure (g 18)
The collective ue is a ue gas exhaust system suitable for collecting
and expelling the combustion products of several appliances installed on
several oors of a building.
The positive pressure collective ues can only be used for type C condensing
appliances. Therefore the B53P/B23P conguration is forbidden. The
installation of boilers under collective pressure ues is allowed exclusively
in G20.
The boiler is sized to operate correctly up to a maximum internal pressure
of the ue no higher than the value of 25 Pa. Check that the fan speed
corresponds to what is shown in the table "technical data".
Make sure that the air intake and exhaust pipes of the combustion products
are watertight.
WARNINGS:
b The appliances connected to a collective pipe must all be of the same
type and have equivalent combustion characteristics
.
b The number of devices connected to a positive pressure collective
pipe is dened by the ue designer
.
The boiler is designed to be connected to a collective ue sized to operate
in conditions where the static pressure of the collective ue pipe can
exceed the static pressure of the collective air duct of 25 Pa in the condition
in which n-1 boilers work at maximum rated heat input and 1 boiler at the
minimum rated heat input allowed by the controls.
b The minimum permissible pressure difference between the ue gas
outlet and the combustion air inlet is -200 Pa (including - 100 Pa of
wind pressure)
.
For both types of exhaust, further accessories are available (curves,
extensions, terminals, etc.) which make possible the ue gas exhaust
congurations foreseen in the boiler booklet.
b The pipes must be installed in such a way as to avoid condensation
sticking which would prevent the correct evacuation of the combustion
products
.
b
A data plate must be present at the connection point with the collective
ue pipe. The plate must include at least the following information:
- the collective ue is sized for boilers C(10) type
- the maximum permissible mass ow of the combustion products
in kg/h
- the dimensions of the connection to the common pipes
- a warning concerning the openings for the air outlet and the entry
of the combustion products of the collective pressure pipe; the-
se openings must be closed and their tightness must be checked
when the boiler is disconnected
- the name of the manufacturer of the collective smoke pipe or its
identication symbol.
10
RESIDENCE
- To start the vent cycle shut off the electrical power for a few seconds;
connect the power again leaving the boiler OFF. Check that the gas tap
is closed.
- At the end of the cycle, if the circuit pressure has dropped, open the lling
tap (B - g. 19) again to bring the pressure back up to recommended
levels (1-1.5 bar)
The boiler is ready after the vent cycle.
- Remove any air in the domestic system (radiators, zone manifolds, etc.)
using the bleed valves.
- Once again check that the system pressure is correct (ideally 1-1.5bar)
and restore the levels if necessary.
- If air is noticed when operating, repeat the vent cycle.
- Once the operations are nished, open the gas tap and ignite the boiler.
At this point it is possible to carry out any heat request.
3.17 Draining the heating system
Before draining, set the boiler to OFF and shut off the electrical supply
setting the system's main switch to “off”.
- Close the heating system's taps (if present).
- Open the de-aeration tap (A - g. 19)
- Connect a pipe to the system discharge valve (C - g. 19), then manually
loosen it to let the water ow out.
- Once the operations are nished, remove the pipe from the system
discharge valve and close the system discharge (C - g. 19) and de-
aeration (A - g. 19) taps again.
3.18 Emptying the domestic hot water circuit
Whenever there is risk of frost, the domestic hot water system must be
emptied in the following way:
- turn off the main water supply tap
- turn on all the hot and cold water taps
- drain the lowest points.
3.19 Condensate siphon
When the boiler is rst started the siphon for collecting the condensate
is empty.
When eliminating air from the boiler, the siphon lls.
- Slowly open the de-aeration tap (A - g. 19) and leave it open until the
amount of water contained in the siphon reaches the ledge.
- Close the de-aeration tap (A- g. 19)

activating the solar collector anti-freeze function.
The factory setting is: - - °C (solar collector anti-freeze disabled).
The parameter can be set with the range -30°C - +5°C.
COLLECTOR T MAX
Parameter for setting the maximum temperature of the collector for the solar
collector pump lockout (system protection).
The pump is then enabled as soon as the temperature of the collector falls
below [COLLECTOR T MAX - 10°C].
The factory setting is 110°C.
The parameter can be set with the range 80°C - 180°C.

Parameter for setting the maximum temperature of the collector for activating
the solar collector cooling function.
The factory setting is 110°C.
The parameter can be set with the range 80°C - 180°C.
Note: the COLLECTOR T PROT value should be lower than COLLECTOR
T MAX.
COLLECTOR T AUTH
Parameter for setting the minimum temperature for enabling the solar
collector pump.
The factory setting is 40°C.
The parameter can be set with the range -20°C - +95°C.
Note: the COLLECTOR T AUTH value should be higher than COLLECTOR
T LOCK.
COLLECTOR T LOCK
This parameter allows you to set the minimum temperature for disabling
the solar collector pump.
The factory setting is 35°C.
The parameter can be set with the range -20°C - +95°C.
Note: the COLLECTOR T LOCK value should be less than COLLECTOR
T AUTH.
PWM COLL PUMP
This parameter allows you to set the PWM modulation period of the solar
pump.
The factory setting is 0min (solar collection pump modulation function
disabled).
The parameter can be set with the range 0min - 30min.
TANK COOLING
Parameter for enabling/disabling the storage cylinder cooling function; there
are two options available:
0= FUNCTION NOT ACTIVE (factory setting)
1= FUNCTION ACTIVE
SOLAR PUMP MODE
Parameter for conguring the operation of the solar collector pump; there are
three options available:
0= OFF (factory setting) ==> the solar collector pump is always off
1= ON ==> the solar collector pump is always on
2= AUTO ==> the solar collector pump switches on and switches off
according to the solar management rules
4.5 Setting the thermoregulation
Enabling THERMOREGULATION occurs in the following way:
access the technical parameters menu, as indicated in the paragraph
"3.21 Access to the parameters"
select the menu CH and then OTR=1.
Thermoregulation only works with the outdoor temperature sensor
connected and active only for the HEATING function.
If OTR = 0 or outdoor temperature probe disconnected the boiler operates
at a xed point.
The temperature measured by the outdoor temperature sensor is displayed
in "4.21 INFO menu" under OUTDOOR TEMP SENS.
The thermoregulation algorithm will not directly use the outdoor
temperature, but rather a calculated outdoor temperature that takes into
account the building's insulation: in buildings that are well insulated, the
outdoor temperature variations will have less impact than those that are
poorly insulated by comparison.
REQUEST FROM OT CHRONOTHERMOSTAT
In this case the delivery setpoint is calculated by the chronothermostat
according to the outdoor temperature value and the difference between the
ambient temperature and the desired ambient temperature.
REQUEST FROM ROOM THERMOSTAT
In this case the delivery setpoint is calculated by the adjustment board
according to the outdoor temperature value so as to obtain an estimated
outdoor temperature of 20° (reference ambient temperature).
There are 2 parameters that compete to calculate the output setpoint:
slope of the compensation curve (KT)
offset on the reference ambient temperature.
Selecting the compensation curve (parameter OTD CURVES - g. 20)
The compensation curve for heating maintains a theoretical temperature of
20°C indoors, when the outdoor temperature is between +20°C and -20°C.
The choice of the curve depends on the minimum outdoor temperature
envisaged (and therefore on the geographical location), and on the delivery
temperature envisaged (and therefore on the type of system). It is carefully
calculated by the installer on the basis of the following formula:
KT = T. outlet envisaged - Tshift
20- min. design external T
Tshift = 30°C standard system
25°C oor installations
If the calculation produces an intermediate value between two curves, you
are advised to choose the compensation curve nearest the value obtained.
Example:
if the value obtained from the calculation is 1.3, this is between
curve 1 and curve 1.5. Choose the nearest curve, i.e. 1.5.
The settable KT values are as follows:
standard system: 1.0-3.0
oor system 0.2-0.8.
Through the interface it is possible to access the menu CH and the parameter
OTD CURVES to set the pre-selected thermoregulation curve:
access the technical parameters menu, as indicated in the paragraph
"3.21 Access to the parameters"
select the menu CH and then OTD CURVES
press the key to conrm
set the desired climatic curve with the and arrow keys
