When cleaning, do not leave any remains of wood or embers on the grate.
All boiler cleaning takes place from the front.
Disconnect the power supply to the boiler before cleaning.
Rake out the ash from the combustion tunnel before each burning cycle.
Ashes may contain embers for a long time after the burning cycle, so
keep them in a non-flammable container with a cover.
Tarring in the combustion chamber does not normally cause any prob
-
lems if the correct burning procedures are followed with an accumulator
tank.
Cleaning the boiler
Rake out the ash from the combustion tunnel before each burn-
ing cycle.
It is normal for tar to form on the walls of the combustion cham-
ber. The tar does not need to be removed because it will burn
off once the layer has reached a certain thickness. The tar does
not affect the efficiency of the boiler, and the output of the boiler
is calculated and dimensioned on the basis of the heat conver-
sion surface area in the flue ducts. The flue ducts must be
kept clean at all times. In a cleaned boiler, less of the
heat escapes with the flue gases. One way of telling
whether it is time for cleaning is to check the flue gas
thermostat. It is a good idea to clean the boiler if the flue gas
temperature is approx. 25SDgrC higher than the temperature in
a clean boiler.
• Open the cleaning hatch, 7.
• Pull out the five turbulators, 30 (x 3) and 31 (x 2), using the
tool 29.
Clean the pipes with the pipe brush.
When cleaning the three upper pipes, be careful not to push
the pipe cleaner through the grating, damaging the fan. Do
not push the pipe cleaner further than the end of the pipe.
You can feel when you have reached the end from the differ-
ence in the amount of force needed to push the cleaner.
Replace the turbulators.
• Open the firewood hatch, 9, and the bypass damper, 8.
Remove the ash on the plate in the upper front edge of the
combustion chamber, 32.
There should always be a small quantity of ash on the ceramic
grate, 34, in order to extend the service life of the grate.
• Open the ash hatch, 10, and remove the inner ash hatch.
Rake out the ash from the combustion tunnel, 33, but leaving
a protective layer of a couple of centimetres.
Clean the chamber around the combustion tunnel.
Close all hatches and dampers.
Chimney sweeping
After the chimney has been swept, unscrew the wingnuts on
the front of the flue pipe, 3 and 18, and remove the cover.
Remove soot and ash. Before restarting the boiler, remove any
soot and ash that has fallen onto the fan and into the collection
chamber 44.
Cleaning the fan
If necessary the fan can be removed and cleaned, You should
handle the fan with care.
• Remove the fan connector, 16, from the boiler plug.
• Unscrew the long nuts, 4a, securing the fan.
• Clean the fan blades carefully so they keep their shape. You
are recommended to use a paintbrush.
• Replace the fan and connect the cables.
