2.1 BOILER ROOM
The boiler room should feature
all the characteristics required by
standards governing liquid fuel
heating systems.
2.2 BOILER ROOM DIMENSIONS
Position the boiler body on the foun-
dation bed, which should be at least
10 cm high. The body should rest on
a surface allowing shifting, possibly
by means of sheet metal. Leave a
clearance between the boiler and
the wall of at least 0.60 m, and
between the top of the casing and
the ceiling of 1 m (0.50 m in the case
of boilers with incorporated D.H.W.
tank). The ceiling height of the boiler
room should be less than 2.5 m.
2.3 CONNECTING UP SYSTEM
When connecting up the water sup-
ply to the boiler, make sure that
the specifications given in fig. 1 are
observed. All connecting unions
should be easy to disconnect by
means of tightening rings. A closed
expansion tank system must be
used.
2.3.1 Accessories (fig. 2)
To ensure boiler efficiency, and a
pressure relief valve set to 3 bar/294
kPa (14) and a hydrometer to check
the system pressure (16).
Install a pressure relief valve cali-
brated to 6 bar/588 kPa (7) on the
boiler water outlet pipe to prevent
the risk of bursting due to excess
pressure build up. If the boiler safety
valve cuts in frequently, install a
5-litre expansion vessel (15) with
maximum operating pressure of 8
bar/784 kPa on the hot water circuit.
The tank should be fitted with a nat-
ural rubber food-grade diaphragm.
The central heating circuit pump
(4) can be installed at the rear of
the boiler in place of the connection
union 1” pos. 3 fig. 4/a (we suggest
you mount the pump without the
WILO-YONOS PARA RS 15/6 RKC-
KU air degasser).
2.3.2 Filling the water system
Before connecting the boiler,
thoroughly flush the system to
eliminate scale which could dam-
age the appliance.
Filling must be done slowly so as to
allow any air bubbles to be bled off
through the air valves.
In closed-circuit heating systems,
the cold water filling pressure and
the pre-charging pressure of the
expansion vessel should be no less
than or equal to the height of the
water head of the installation (e.g.
for water head of 5 meters, the
vessel pre-charging pressure and
installation filling pressure should
be at least 0.5 bar).
2.3.3 D.H.W. production
During the preparation of hot water,
the circulating pump installed on the
boiler circuit remains in operation
until the boiler thermostat probe
detects the pre-selected value.
Once the boiler thermostat has
reach the set point, and the selec-
tor has been set to winter opera-
tion with the room thermostat on
demand, the central heating circuit
pump (not supplied) can be actu-
ated.
All residual air in the boiler coils
must be bled at the first start-up to
ensure proper operation.
To facilitate this operation, position
the slot of the release screw on the
check valve horizontally (6 fig. 2).
Once the air has been bled, return
the screw to its original position.
Hot water for sanitary use is pre-
pared by the boiler in AISI 316L
stainless steel, which is fitted with
a special spiral-shaped stainless
steel heat exchanger, a magnesium
anode to protect the boiler and an in-
spection flange to simplify checking
and cleaning.
2.3.4 Characteristics
of feedwater
To prevent lime scale and damage to
the tap water exchanger, the water
supplied should have a hardness of
no more than 20°F.
In all cases the water used should
be tested and adequate treatment
devices should be installed. To pre-
vent lime scale or deposits on the
primary exchanger, the water used
to supply the heating circuit should
must be treated in accordance with
UNI-CTI 8065 standards.
The water used for the central hea-
ting system should be treated in the
following cases:
– For extensive systems (with high
contents of water).
– Frequent addition of water into the
system.
– Should it be necessary to empty
the system either partially or
totally.
2.4 CONNECTION OF
CONDENSATION
WATER TRAP (fig. 5)
The drip board and its water trap
must be connected to a civil drain
through a pipe (ø 25) with a slope of
at least 5 mm per metre to ensure
drainage of condensation water.
The plastic pipes normally used
for civil drains are the only type
of pipe which is appropriate for
conveying condensation to the buil-
ding’s sewer pipes.

2.5 ELECTRICAL
CONNECTION (fig. 5/a)
The boiler is fitted with an electricity
cable, and requires a a single-phase
power supply of 230V - 50Hz through
the main switch protected by fuses.
The room thermostat (required for
enhanced room temperature con-
trol) should be installed as shown in
fig. 5/a. Connect the burner and sys-
tem circulation pump power cables
supplied.
NO TE: Device must be connected to
an efficient earthing system.

3.1 COMMISSIONING
THE BOILER
When commissioning the boiler
always make sure that:
– the system has been filled with
water and adequately vented;
– the flow and return valves are
fully open;
– the flue and chimney are free
from obstructions;
– the electrical connections to the
mains and the earthing are cor-
rect;
– no flammable liquids or materials
are near the boiler;
– check that the circulating pump is
not locked.
3.2 LIGHTING AND
OPERATION
3.2.1 Lighting the boiler (fig. 6)
To light the boiler proceed as fol-
lows:
– switch on the main switch (1); the
green light turns on to indicate
that the appliance is powered (3).
The burner will start;
– set the stat knob (7) to the desired
D.H.W. temperature.
The boiler pump will continue
operating until the preset tem-
perature has been reached.
While the water is being heated,
the boiler will continue automatic
operation to maintain the heat-
ing temperature shown on the
thermometer (5) around 80°C by
means of the limit stat (6);
– once the water has been heated
with the selector (2) set to the
summer function position, the
burner and the circulating pump
will cease operation; when the
selector (2) is set to the winter
position, the system pump con-
trolled by the room stat will start
up.
In this case, operation of the burn-
er will be controlled by the boiler
stat (8) at the preset temperature;
– for best results, set the boiler
stat knob (8) to a temperature no
lower than 60°C to prevent the
formation of condensate.
The set temperature value can be
checked on the thermometer (5).

perature exceeds 95°C.
To restart the boiler, unscrew the
black cover and press the button
underneath.
If the problem occurs frequently,
call an authorised technical assis-
tance centre for the necessary
checks to be carried out.
3.2.3 System filling (fig. 6)
If the orange LED (9) switches on due
to the enabling of the water pressu-
re switch and stops the boiler, it is
possible to restart it by resetting
the plant pressure to 1-1.2 bar (98-
117.6 kPa). The system pressure is
checked through the hydrometer
mounted on the heating delivery
tube (16 fig. 2).
3.2.4 Turning OFF boiler (fig. 6)
To turn off the boiler, cut off the volt-
age by pressing the mains switch (1).
Close both the gas-feed pipe tap and
the water tap if the boiler remains
inoperative for a long period.
3.3 REGULAR CLEANING
Maintenance of the boiler should be
carried out annually by an autho-
rised service engineer.
Disconnect the boiler from the
electrical supply before servicing
or maintenance is carried out.
3.3.1 Smoke side boiler (fig. 7)
To carry out cleaning of the smoke
passages remove the screws that
fix the door to the body of the boiler
and with the special cleaning brush
clean the internal surfaces and the
smoke evacuation tube well, remov-
ing any deposits. Once the mainte-
nance is compled, the baffles have
to be fitted onto the original posi-
tions.

the guarantee null and void.
To access the anode, remove the
inspection flange that enables the
boiler to be checked and cleaned.
3.3.3 Dismantling the skirt (fig. 9)
The shell can be completely disas-
sembled for an easy maintenance of
the boiler by following the numeric
steps shown in fig. 9.
3.3.4 Fault finding
Herefater we outline a number of
potential problems that may occur
on the appliance and the relevant
list of actions required.
A working fault, in most cases, pro-
vocates the “lock out” signal onto
the control panel of the control
box.
When this light turns on, the
burner can operate again only
after the reset button has been
pressed; if this has been done
and a regular ignition occurs, it
means the failure can be defined
momentary and not dangerous.
On the contrary, if the “lock out”
stays, the cause of the fault, as
well as the relevant action must
be made according to the follow-
ing chart:
The burner does not ignite
– Check the electric connections.
– Check the regular fuel flow, the
cleanness of the filters, of the
nozzle and air vent from the tube.
– Check the regular spark ignition
and the proper function of the
burner.
The burner ignites regularly but
the flame goes out immediately
– Check the flame detection, the air
calibration and the function of the
appliance.
Difficulty in regulating the burner
and/or lack of yield
– Check: the regular flow of fuel, the
cleanness of the boiler, the non
obstruction of the smoke duct, the
real input supplied by the burner
and its cleanness (dust).
The boiler gets dirty easily
– Check the burner regulator
(smoke analysis), the fuel quan-
tity, the flue obstruction and the
cleanness of the air duct of the
burner (dust).
The boiler does not heat up
– Control the cleanness of the shell,
the matching, the adjustment, the
burner performances, the pre-
adjusted temperature, the correct
function and position of the regu-
lation stat.
– Make sure that the boiler is suffi-
ciently powerful for the appliance.
Smell of unburnt products
– Control the cleanness of the boiler
shell and the flue, the airtight-
ness of the boiler and of the flue
ducts (door, combustion chamber,

3.4 ANTIFREEZE PROTECTION
In freezing weather, make sure that
the heating system continues to fun-
ction and that the rooms are kept
warm enough, including the room in
which the boiler is installed; if this
cannot be done, both the boiler and
the heating system must be comple-
tely emptied.
Completely emptying the system
also means emptying the hot water
tank and the hot water heating coil.
3.5 USER WARNINGS
When faults occur and/or the equip-
ment does not operate correctly,
turn it off, without attempting to
make any repairs or take direct
action. For any operation only con-
tact the authorised technical per-
sonnel in your area.
3.6
