Preliminary checks

The initial start-up of the ESTELLE HE ErP boiler must be car-
ried 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 contact-
ing 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 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) water
pressure is between 1 and 1.2 bar (98–117.6 kPa) and
a loading/filling valve (B).
66
– 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).

Ignition

After completing the preliminary checks, to start up the boiler:
– adjust the room thermostat to the desired temperature (~
20°C)
Fig. 1
– set the main system switch to "ON"
– adjust the heating thermostat (4) to roughly 3/4 of the adjust-
ment range (corresponding to roughly 75°C)
– press the main switch (6) 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 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.
