6. 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
The innovative technology of our combination stove INDUO offers
you a maximum of heating comfort, depending on the availability
of the fuel the stove can be heated with pellets and / or logs without
any modification�
Both cases are solid fuels 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�
Burnback and flue gas flaps
The combi stove safety concept is based on double safeguards� If
faultless operation is no longer ensured due to a component defect
or power cut, the burnback flap in the pellet chute is released� This
directly interrupts the connection between the pellet container
and push in screw� Thus preventing pellet burnback� Closing the
burnback flap at the same time opens the flue gas flap thus ensuring
safe burning off of the fuel in the combustion chamber�
Note
Check with every maintenance / cleaning the correct operation of
the flue flaps�
Overheating
A safety temperature limiter (STL) switches the stove off
automatically on overheating� Once the stove has cooled, the STB
at the stove rear must be unlocked manually (pressed)� The stove is
ready for operation again after acknowledging the error message
at the touch display and activating the burnback and flue gas flap
(see ACTIVATING THE BURNBACK AND FLUE GAS FLAP)
� The
operating mode set is retained�
Note
Maintenance and cleaning work must be performed if overheating
occurs! If this error recurs, operation without danger is no longer
guaranteed; notify customer service immediately�
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�
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�
