Preliminary checks
The initial start-up of the ESTELLE HE B4 INOX ErP boiler must
be carried out by professionally qualified personnel, after which
the appliance can function automatically. It may be necessary
for the user to restart the appliance autonomously, without con-
tacting 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
a
WARNING
Sime ESTELLE HE B4 INOX ErP boilers are NOT equipped
with a system filling device. The system must be fitted
with a pressure gauge (A), to check that the (cold) wa-
ter pressure is between 1 and 1.2 bar (98–117.6 kPa)
and a loading/filling valve (B).
70
– 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).

After completing the preliminary checks, to start up the boiler:
– adjust the room thermostat to the desired temperature (~
9
20°C)
Fig. 1
– set the main system switch to "ON"
– adjust the calorifier thermostat (4) to roughly 3/4 of the ad-
justment range (corresponding to roughly 50°C)
– adjust the heating thermostat (5) to roughly 3/4 of the adjust-
ment range (corresponding to roughly 75°C)
– press the main switch (8) on the control panel and verify that
the green LED switches on (3)

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 maximum power until the tem-
perature set on the calorifier thermostat is reached.
Once the domestic hot water calorifier has heated up, the boiler
will switch to heating mode.
The thermometer will show the temperature value of the water
in the appliance, measured at that time.
