DESCRIPTION OF THE APPLIANCE
5.1
Characteristics
Sime ESTELLE HE B4 INOX ErP
Moreover, they are equipped with a heat recovery device on the fume side that classifies them as "condensing boilers". They are spe-
cially designed for users who privilege high performances, silent operation and compact dimensions.
boilers are the version for space heating and for domestic hot water production with a stainless steel calorifier
ESTELLE HE B4 INOX ErP
that stores up to 110 litres. 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 according to the laws in force in the country where the
appliance is used. They can be converted into TYPE C23P (sealed) devices using the available ACCESSORIES KITS (refer to the para-
graph 6.1.1 Optional accessories ) which allow the appliance to draw combustion air directly from outside the room where it is installed.
The broad heat exchange surface of the cast iron body combined with the heat recovery device on the fume side allow 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 calorifier
thermostat (4) and the heating thermostat (5) to roughly 3/4 of
the adjustment range (respectively around 50 and 75°C), shift-
ing the switch (9) to Winter mode and then activating the general
and main switches (8) to power the appliance electrically. The
green signalling LED (3) will light up to signal that the system
is powered.
When a heat request arrives, with the room thermostat or the
calorifier thermostat in request mode, the fuel will start heating
(for burners equipped with fuel pre-heaters) for a few minutes
with the burner stationary, then burner pre-ventilation will start
followed by the subsequent ignition of the flame and the starting
up of the system pump and/or calorifier.
The flame will remain on until the temperature set through
thermostats (4) and (5) 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 requesting heat 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
shown in the documentation supplied with the burner
installed.

cast iron and condensing boilers are configured for operating with diesel blown-air Low NOx burners.
If there is a domestic hot water request, during heating mode
operation, the boiler will automatically switch the operating
mode to satisfy the current request.
