5 BOILER OPERATION
The heating operation is performed with log wood
or pellet. Due to the separate combustion
chambers there can be flexible switched between
log wood and pellets operation.
5.1 Preparation for heating up
with log wood
If possible, store enough fuel for two or three
combustion processes near the boiler room.
Prepare firewood
The firewood must correspond to size
(circumference 8- 10 cm) and dimensions to the
size of the boiler. Firewood without bark burns
better.
5.2 Heating up
Warning: Risk of system damage
due to improper maintenance!
Wrong position or lack of firebricks
inside the boiler can lead to
damage or destruction of the
boiler.
◼
Before heating up the boiler,
check the position of the
firebricks.
Warning: Risk of system damage
due to improper maintenance!
Excessive fuel feeding can cause
overheating and damage to the
boiler.
◼
Adapt the amount of fuel to
the
energy absorption
capacity of the heating
system.
Crucial for the clean burn-off in the
boiler are the correct operation of
the boiler as well as a sufficient
feed pressure of the exhaust
system.
When heating up with log wood
there may occur a greater smoke
production at the chimney.
In the following a possibility for the heating up of
the boiler is described. Depending on the ambient
conditions (draft, exhaust system, wood, and so
on) other heating up processes may be better.
Get conversant with the boiler and find out the
best handling to use. Test the best opportunity for
heating up the boiler.
Please note always the safety notes!
◼
Switch on the main switch [2] and regulator
(

– button, page). The regulator
displays status 1.
1 … Cable bushing
2 ... Main switch
3 … Electric supply
◼
After the casing door is opened the “burning”
phase (Status: 2) starts automatically.
If it is not desired or necessary to
heat up the boiler, this process
can be interrupted with a long
press of the On/Off button.
◼
To form a good flame, it is recommended that
the lower third of the filling shaft be filled with
small pieces of wood.
◼
After that normally chopped wood (size
around 8 cm) can be used for filling.
◼
Then close filling door and open the firing
door (4) and fire up with an oil ignition, wood
shavings or cardboard.
◼
When the flue gas temperature is 120°C,
close all doors.
By sufficient feed pressure a fire bed (chimney
flue) is built up and the wood in the filling room is
burning from bottom to top.
