DESCRIPTION OF THE APPLIANCE

5.1

Characteristics

Sime ESTELLE HE ErP cast iron and condensing boilers are configured for operating with diesel blown-air Low NOx burners. Moreover,
they are equipped with a heat recovery device on the fume side that classifies them as "condensing boilers". They are specially de-
signed for users who privilege high performances, silent operation and compact dimensions.
boilers are the version for space heating only.
ESTELLE HE ErP
All ESTELLE HE ErP boilers are TYPE B23P (open), which means that the burner draws air from the environment in which it is installed,
therefore the room MUST include adequate vents sized according to the laws in force in the country where the appliance is used.
and ESTELLE HE 4 ErP models can be converted into TYPE C23P (sealed) devices, using the available ACCESSORIES
ESTELLE HE 3 ErP
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.
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 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).
