1.2 Preliminary checks
The initial start-up of the RONDÒ/ESTELLE 4-5-6-7 ErP BE boiler
must be carried out by professionally qualified personnel, after
which the appliance can function automatically. It may be neces-
sary for the user to restart the appliance autonomously, without
contacting the technician; for example, after a holiday. In this
case, the following checks and operations must be carried out:
–check that the fuel and water circuit shut-off valves are open
Fig. 2
a
WARNING
Sime RONDÒ/ESTELLE 4-5-6-7 ErP BE boilers are NOT
equipped with a system filling device. The system
must be fitted with a pressure gauge (A), to check that
the (cold) water pressure is between 1 and 1.2 bar
(98–117.6 kPa) and a loading/filling valve (B).
–check on the pressure gauge (A) that the pressure of the heat-
ing system, when cold, is
1–1.2 bar . If not, open the filling valve
(B) and refill the heating system until the pressure gauge (A)
shows a reading of
1–1.2 bar
–close the filling valve (B).

The burner will pre-heat the fuel (for burners equipped with fuel
pre-heaters) and perform the pre-ventilation cycle; it will then
ignite the flame and operate at its adjusted power until the tem-
perature set on the room thermostat is reached.
The thermometer will show the temperature value of the water
in the appliance, measured at that time.

1.4 Adjusting the heating temperature
If the heating temperature must be increased or decreased,
turn the knob (4) until the desired value is reached. The temper-
ature can be set to between 45°C and 85°C.

WARNING
To ensure constantly optimal performance of the gen-
erator, we suggest
NOT to adjust the heating thermostat
to below the 60°C working temperature
.

1.5 Possible faults
1.5.1 Safety thermostat
The manual-reset safety thermostat intervenes by triggering
the immediate lock-out of the burner, when the temperature
exceeds 100°C. The intervention of the safety thermostat is not
signalled but can be detected by the boiler thermostat (T>100°
C). To reactivate the appliance, wait until the temperature in-
dicated by the thermostat falls to roughly 75° C then unscrew
the protective cap and press the underlying shaft. Wait for the
completion of the fuel pre-heating and start-up phases until the
flame appears.
Fig. 7
a
WARNING
If the reactivation fails, DO NOT REPEAT it and wait for
qualified technical personnel to intervene.
1.5.2 Burner lock-out
If any ignition or operating anomalies occur, the boiler will run
a “LOCK-OUT” and the
PSB button will light up red. To reset the
burner ignition conditions, press the burner unlock button (PSB)
until the flame appears. This operation can be repeated 2–3
times at the most and, should it fail, wait for qualified technical
personnel to intervene.
PSB
Fig. 8

WARNING
Check that there is enough fuel in the tank and that the
shut-off valves are open. Once the tank has been filled, it
is advisable to interrupt the boiler’s operation for roughly
one hour.
1.5.3 System low pressure (replenishment)
Sime RONDÒ/ESTELLE 4-5-6-7 ErP BE boilers are NOT equipped
with a system filling device. The system must be fitted with a
pressure gauge (A), to check that the (cold) water pressure is
between
1 and 1.2 bar (98–117.6 kPa) and a loading/filling valve
(B).
When the system water pressure indicated on the pressure
gauge (A) falls below
1 bar (98 kPa) , the unit must be filled.
To do this:
–open the filling valve (B) to raise the pressure until it reaches
the correct value, between
1 and 1.2 bar (98–117.6 kPa)
–close the valve (B)
NOTE: if the pressure exceeds the maximum value specified
above, open the relief valve of any radiator (some water will
come out) until the correct value is reached.

5DESCRIPTION OF THE APPLIANCE
5.1 Characteristics
Sime RONDÒ/ESTELLE 4-5-6-7 ErP BE cast iron boilers are configured for operating with diesel blown-air Low NOx burners. They are
specially designed for users who privilege high performances, silent operation and compact dimensions.
RONDÒ/ESTELLE 4-5-6-7 ErP BE boilers are the version for space heating only. They can be TYPE B23P (open) devices, when the burner
draws combustion air from the environment in which they are installed, therefore the room MUST include adequate vents sized ac-
cording to the laws in force in the country where the appliance is used.
RONDÒ / ESTELLE 4 ErP BE and RONDÒ / ESTELLE 5 ErP BE models can be converted into TYPE C23P (sealed) devices, using the available
ACCESSORIES KITS (see the paragraph
6.1.1 Optional accessories ) which allow the appliance to draw combustion air directly from
outside the room where it is installed.
ESTELLE ErP BE boilers are equipped with a reversible door that opens towards the right. By inverting the pin, the door opening direc-
tion can be switched to the left side.
The door pin is not present on
RONDÒ ErP BE boilers. They are supplied in 3 separate packages: boiler body, jacket, control panel and
document kit.
The broad heat exchange surface of the cast iron body allows to obtain high performances that ensure considerable savings in terms
of running costs.
5.2 Operation
Prior to starting up the boiler, we suggest setting the heating
thermostat (4) to roughly 3/4 of the adjustment range (roughly
75°C) and then activating the general and main switches (6) to
power the system electrically. The green signalling LED (3) will
light up to signal that the system is powered.
When a heat request arrives, with the thermostat in request
mode, the fuel will start heating (for burners fitted with a fuel
pre-heater) for a few minutes with the burner stationary. The
following operations occur in sequence: powering of the burner
and of the ignition transformer; ignition of the flame and start-
ing up of the system pump.
The flame will remain on until the temperature set through the
heating thermostat (4) of the control panel has been reached,
while the system pump continues to operate in order to use the
heat generated (available). The burner will then switch on and
off in an alternating manner until the temperature requested by
the room thermostat is reached.
The temperature of the water contained in the cast iron body will
appear on the thermometer (2).

CAUTION
The diagram of the operating sequences/phases is

installed.

5.3 Check and safety devices
RONDÒ/ESTELLE 4-5-6-7 ErP BE appliances are equipped with
the following control and command devices:
– thermal safety thermostat 100°C
– heating thermostat (min 45°C - max 85°C)
– thermometer (0-120°C).

1 Packaging label: located on the outside of the packaging, it includes the code and serial number of the boiler in addition to the
barcode.
2 Technical data plate: it is located on the right-hand side of the boiler and includes the technical data, appliance performance data
and any other information required by law in the country where the appliance will be used.

When the burner is installed at altitudes up to maximum 1300 m.a.s.l., due to the lower air density, the factory adjustments for the
burner must be modified as follows:
–Keep the nozzle mounted in the factory
–Do not vary the position of the combustion head
–Gradually reduce the pump pressure to reduce the fuel flow rate
–Adjust the air shutter by taking the following readings:
-CO
