A simple quality test: Put a few wood pellets in a glass of
water:
Good quality:
Pellets sink
Lower quality:
Pellets float.
The use of lower-quality or unauthorised fuel adversely
affects the operation of your pellet stove and may in
addition lead to the lapse of the guarantee and the
associated product liability. Unauthorised fuels include
woodchips, straw and maize. Burning wood pellets of
poor quality leads to shortening of the cleaning intervals
and to increased fuel consumption, so the pellet tank
has to be filled more frequently.
Wood pellets are packed in plastic or paper sacks. To
ensure problem-free combustion of the wood pellets it is
necessary to dry the fuel as much as possible and to
transport and store it free from dirt. On contact with
moisture, pellets swell considerably.
When filling the storage container with wood pellets,
make sure that the pellet sacks do not come into contact
with the hot surfaces of the stove.
Two kilograms of wood pellets have about the same
energy content as a litre of “extra light heating oil.” In
terms of volume, 3 m
3
of wood pellets are equivalent to
about 1,000 litres of heating oil. Variations in heat output
by the pellet stove are caused not only by the quality of
the pellets but also by the raw material of the wood (type
of wood).
7.2.
Commissioning your pellet stove
The materials making up your pellet stove must
gradually get used to the heat generation. By careful
warming up you avoid cracks in the combustion
chamber plates, damage to the paintwork and warping
of materials. So do not set the target temperature too
high on the control unit (about 1.
5°C to 2°C higher than
the current room temperature).
Before commissioning, remove any stickers and
any accessories from the pellet tank and the
combustion chamber.
Check that the combustion chamber cladding is
attached to its fastenings. (This might have
slipped out of its position as a result of the
transportation or installation of the stove).
Check that the combustion pot fits perfectly in its
frame.
Close the combustion chamber door.
Fill the storage container with standard wood
pellets
(Ø 6 mm).
Insert the mains cable.
Once the toggle switch has been set to ON, the
control unit commences initialisation. This
process takes a few seconds.
After initialisation, the Information screen
appears
– press the right key (Menu) – move
cursor to Operating mode
– press the right key
(Select)
– select the desired operating mode
with the cursor
– press the right key (Save).
Tip!!
Only when
commissioning
, place about 30
pellets in the burner. This will speed up the
ignition process.
General:
If the ignition phase could not be successfully
run i.e. no flame generation or the required
temperature could not be reached at the flue
gas thermosensor, then a safety shutdown is
initiated and
an error message generated (“Ignition
phase target temp. flue gas not reached
– check burner
– date and time”).
Note: Any smoke generation caused by further
drying of the paint stops after a short while. Please
properly ventilate the room where the stove is
installed. However, the paint does not contain any
toxic vapours.
8. Cleaning and maintenance work
The functioning of your device depends to a large extent
on regular expert maintenance. Because of the ash
accumulation resulting from the combustion of wood
pellets, constantly recurring cleaning and maintenance
work needs to be carried out. This will permit operation
to be as trouble-free as possible.
The frequency of maintenance in turn depends to a large
extent on the pellet quality (ash content). Quality pellets
have a low ash content of about 0.2-0.3%. However, if
the ash content is higher (0.5% and over), the interval
from maintenance to maintenance is reduced and the
accumulation of ash increases by 2 or 3 times. This
results in lower heat output and an increased fan
rotation
speed.
We
therefore
recommend
checking and/or cleaning the flue gas passes
after 1,000 kg of pellets at the latest. (See
Figure 8 a+d).
Attention!
Devices that are not maintained in accordance with
our specifications must not be operated. Failure to
observe this point will invalidate all guarantee
claims.
As soon as you detect ash and clinker deposits in the
cold combustion pot, it must be cleaned. (
See Figures 5
+6).
If this is not done, the clinker will continue to
accumulate. Then the device will no longer be able to
ignite properly. Pellets can pile up in the combustion pot.
In extreme cases, this can reach all the way back to the
pellet chute. Backfire in the pellet container and
smouldering in the pellet tank might possibly result.
This will destroy your device and is not covered in
your guarantee
.
Attention!
Before starting any cleaning work, the stove must be
cool down and set to "Off"! Once the cleaning work
is completed, the correct operating status of the
device must be re-established: Put the combustion
pot in correctly, close the combustion chamber
door.
