Function
Prior to the initial start−up, check whether
the system contains water and has been
vented.
The wood gasification (pyrolysis) takes
place inside the stainless steel hopper
through the incandescent bed. The
combustible wood gases created by this
process are sucked into the ceramic
combustion chamber and there, transfer
their heat via the heating surfaces. This
quickly raises the combustion chamber
temperature to a high level, resulting in
clean combustion both in partial and in
full load operation.
Before heating up or re−filling with fuel,
operate the heating surface cleaning lever
L 3 5 times.
For heating up, the feed flap is pulled out
after opening the feed door, and the
exposed grate is covered with crumpled
paper balls up to the top edge of the lined
de−gassing zone (approx. 5 cm). The
paper is then covered with a layer of
dried chippings, thin kindling or course
cuttings. Several layers of split logs with
a height (edge) of 4 to 6 cm and
preferably without air gaps should then
be inserted. Then, the feed hopper can be
filled with split logs up to 45 to 55 cm in
length and a max. height (edge) of 15 cm.
A complete filling of Vitolig 200 can only
be recommended if the heating water
buffer storage unit is cold and/or the
outside temperature is low (ensure
sufficient heat consumption).
Fill with less wood for summer operation.
After pressing the system On/Off switch
at the control unit, the unit tests itself and
all connected sensors; at the end the
boiler water temperature is displayed.
To fire Vitolig 200, the ash door and the
upright grate behind the door are opened.
Ignite the paper and press the heat−up
button on the boiler control panel. Close
the upright grate and the ash door, when
the paper is thoroughly burned through
(approx. 20 to 30 seconds).
2 Product information
The r.h. side of Vitolig 200 comprises the
A
variable speed vacuum draught fan for a
modulating matching of the system to the
output A, the large stainless steel feed
hopper for 50 cm logs with a large feed
door B, the de−gassing zone with fire
clay lining C and the large ash box with
door D.
The l.h. side of the boiler is the actual
B
combustion part of Vitolig 200. Primary
and secondary air apertures with variable
control E and the combustion chamber
constructed from special ceramics F
with temperature sensor provide
excellent combustion results. The large
clean−out door provides easy access to
the heating surfaces G to enable
thorough cleaning from the front. A
100 mm thick thermal insulation H
reduces cool−down losses.
The ready−to−connect control unit K is
C
easily accessible for maintenance
purposes.
D
Depending on the fill level of the hopper,
the fuel quality and the heat
consumption, combustion may last from
4 to 13.5 hours. Do not open the feed
door for at least three hours after heat−up.
Open the feed door up to the lock
position when re−filling and leave in that
position for at least 15 seconds. The
carbonisation gases inside the hopper
will then be withdrawn by the vacuum
draught fan, and the feed door can be
fully opened. If sufficient incandescence
is present, distribute this evenly over the
grate and pile up split logs horizontally as
for the heating−up process. If insufficient
incandescence is present (the grate is
visible), proceed as for heating up.
At the end of combustion, the fan runs on
for 20 minutes at maximum speed and is
then switched off. This make best use of
remaining incandescence.
