Riello RESIDENCE KIS Series Installer And User Manual page 7

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 floating)
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 - CIRCULATOR 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 flow 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 flow 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 sufficient circulation (system flow at
maximum speed lower than 600 litres/hour).
Used when there are bottles of mixture with high flow rate in the downstream
circuit.
Operationally:
ƒ Enter parameter PUMP CONTROL TYPE
ƒ 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:
- find and unscrew the 2 screws (A - fig. 11) fixing the casing to the boiler
levering the two fixing clips (C - fig. 11), detach the bottom part of the
casing
- lift the casing upwards to release it from the top tabs (B - fig. 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 flue 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 flue gases accessories.
A single flue 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 flue 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.

The straight length includes the first bend (connection into the boiler),
terminals and joints. An exception is made for the vertical Ø 60-100
mm coaxial pipe, whose straight length excludes bends.
b
The boiler is supplied without the flue gas exhaust/air suction kit,
since it is possible to use the accessories for condensing appliances
that best fit the installation characteristics (see catalogue).
