4. TECHNOLOGY AND SAFETY FUNCTIONS
The technological advances in your new combi stove are the result of
years of testing and practical experience� The practical advantages
of your pellet/log stove are convincing:
The range of operating modes leaves nothing to be desired� The
automatic fuel detection means the operating mode can be changed
at any time (simply add logs during pellet operation or ignite logs
with the pellet burner)�
Manually regulated currentless log operation is also possible� This
ensures faultless operation even in the case of longer power cuts�
Operating comfort
The microprocessor-controlled combustion regulation optimises
the interaction of flue gas blower, air flap position and screw using
the current combustion chamber temperature� This guarantees
optimum combustion and operating status in both pellet and log
operation�
All function can be regulated centrally using the integrated touch
display� The intuitive graphic interface permits easy operation; all
the settings can be made quickly and simply�
Top efficiency - lowest emissions
A very great heat exchange surface together with optimum
combustion air control leads to excellent fuel utilisation�
Fine continuous pellet dosing in an optimised burner pot made of
high-quality grey cast iron leads to virtually complete combustion
with very good exhaust gas values - and this is guaranteed in every
operating phase�
The combination of temperature-controlled automatic air regulation
and optimised wood retainer geometry enable combustion with
minimum emissions at top efficiency in log operation�
Note
During operation, the flame noise, pellets dropping and actuation
of the electronic components are audible due to the automatic
control�
Note
Solid fuels like pellets and logs that can cause a fogging of the
door glass during the combustion, particularly with the very fine
ash from wood pellets�
By external influences such as chimney draft or pellet quality this
coating can be very bright or dark black (especially with low power
)� This is a natural process and is not a shortage�
We therefore recommend regular cleaning of the door glass, just
because soot is an excellent insulator and thus the heat dissipation
can be reduced�
If the stove is heated according to its function in the combined
operation, a significant improvement can be achieved due to the
higher temperatures in log wood mode�
Low-temperature shutdown
The unit switches off if the stove cools below a minimum temperature�
This switch-off may occur if pellet ignition is delayed�
Electrical excess current protection
The stove has a main fuse (at the rear) to protect against excess
current�
Flue gas flap
If faultless operation is no longer ensured due to a component
defect or power cut, the fluegas flap is opened� The flue gas flows
directly in the chimney� This ensures a safe burning off of the fuel in
the combustion chamber�
Note
Be sure to close the flue gas flap for a proper, automatic function
of the log mode�
Note
Check with every maintenance / cleaning the correct operation of
the flue flaps�
Automatic cleaning cycle
The speed of the flue gas fan is increased every hour for a short
period to blow ash from the burn pot, increasing the operational
safety� The status indicator CLEANING appears on the display�
Every 5 hours (interval adjustable) an additionally automatic cleaning
cycle is performed� The stove stops, the automatic cleaning tilts the
grid and then re-ignites the stove� The status indicator CLEANING
appears on the display continuously� The cleaning procedure with
tilting the grid is to convey ash and clinker from the burn pot into
the ash drawer�
Note
At runtime of the cleaning cycle occures a noise due to the turning
grid (stove start or big cleaning)�
Note
This additional function does not replace a manual cleaning as
described in CLEANING and MAINTENANCE, as this is absolutely
necessary to do regularly�
Component monitoring
All the electrical components used are continuously monitored
during operation� If a component is defective or can no longer be
actuated correctly, then operation is stopped and a warning or error
message is issued (see MANUAL TOUCH DISPLAY)�
Auger motor monitoring
Too long or wet pellets as well as pellets with too high dust content
(see BRIEF INFORMATION ON FUEL PELLETS) can cause so-called
“auger jammers” in the auger channel� This may also happen if the
pellets accumulate in the burn pot and the backlog reaches into
the chute� The auger motor reacts in both cases with an increased
current consumption, which causes the error message: INSERTION
MOTOR JAMMED� The stove will be stopped� Please call the customer
service immediately�
