Technical description
Iwabo Villa S2 is a further development of the Iwabo Villa S1 pellet burner at making the
appliance easier to handle for both the person installing it and the user.
Iwabo Villa S2 is built according to the
drop-feed principle
by which the pellets due to gravity
fall from the
feeder auger
through the
feeding hose
and the
drop tube
down onto the
grate
,
where
combustion
takes a place.
Iwabo Villa S2 features an
electrical ignition
which automatically ignits the pellets falling
down onto the
grate.
Ignition takes place only after the
thermostat
has given a start signal to
the burner.
Iwabo Villa S2 has its own built-in
thermostat
(for the case of no boiler thermostat in-built) Its
.
boiler temperature sensor
must be connected to a suitable
plunger
inside the boiler.
Cut-in and
cut-out temperatures
are selected via the burner's
menu push buttons.
Informations on current
operating data is shown on the
display
.
NOTE: The bulb of the boiler temperature sensor has not be treated with contact fluid or
paste.
Iwabo Villa S2 has three factory-set output options: 12 kW, 15 kW and 18 kW.
The output option selected is shown on the display during operation. The output can be
selected by using the burners menu push buttons and the informations shown on the display.
These output options can be also varied between 10-20kW in the "Advanced menu"
Iwabo Villa S2 has an automatic grate cleaning mechanism. When the thermostat has reached
the cut-off temperature, a burning out will take a place, after which the grate is pushed out, at
the same time being scrapped clean. This enables longer intervals of operation in which the
burner will not need to be taken out from the boiler. The ash space in the boiler determines the
amount of pellets that can be burned up before the ash must be removed. However, the
convection parts in the boiler must be cleaned on a regular basis in order to maintain the high
heating efficiency.
Iwabo Villa S2 in intended for heating with wood pellets that have the diameter of 6-10 mm.
Iwabo Villa S2 is manufactured according to the rules and regulations applicable in the
industry and has been tested and approved in accordance with the Low-Voltage Directive
(LVD) as well as the Directive concerning electromagnetic disturbances (EMC).
