The pellet stove can be operated either with wood pellets or billet wood.
In addition to heating the room where the appliance is installed, the appliance
can also be used for cooking and baking when it is running on firewood. With
appliances featuring a central heating insert (type designation –Z, optional
equipment) hot water is also generated. The heat is transferred to the heating
system by this medium (reservoir, heating circuit, etc.). The cooking plate,
stove body, viewing window, etc. give off radiant heat.
For heating, switch the appliance on, it regulates either according to the pre-set
heating output when operating on pellets or according to the set temperature
of the boiler when operating appliances with central heating insert.
The set temperature of the boiler can be influenced by the setting summer
mode /winter mode. In addition, the output of the appliance can be affected
by setting the power levels. Once the boiler has achieved the preset tempera-
ture, the selected power level limits the upward adjustment range of the pellet
burner (for example this is necessary for cooking or baking). The switching on/
off process of the appliance can be automated through an integrated automatic
operation with a weekly operation schedule or by means of a remote control
unit.
Starting the appliance, irrespective of whether this is done manually or auto-
matically, the tilting grate is cleaned automatically. The pellets are transported
to the combustion chamber via the auger (with integrated rotary air lock as
back-burn protection) and subsequently electrically ignited. The auger auto-
matically supplies more pellets. The oxygen required for combustion flows in a
controlled way to the combustion chamber.
In the combustion chamber of the pellet module and in the subsequent firebox
of the stove the gases produced during combustion burn off – heat is radiated
via the exterior of the appliance as well as the heat exchanger surfaces. An ex-
tract fan, matching the amount of fuel and required combustion air, provides a
stable negative pressure in the boiler and consequently ensures that flue gases
escape through the chimney.
The pellet stove can be operated either with
wood pellets
or
billet wood
.
Operation with pellets
The operation with pellets is predominantly suitable for heating the room
where the appliance is installed. In this case the appliance is controlled by the
use of preset control variables. Cooking operation and oven operation is only
possible to a limited extent (the output can be increased by adding firewood).
Appliances equipped with a central heating insert (optional equipment) can
also generate hot water. The heat is transferred to the heating system (reser-
voir, heating circuit, etc.).
Operation with firewood
In addition to the operation with pellets, the appliance can also be convention-
ally heated with firewood. The basic functions of heating up and operating the
oven are comparable to that of a normal wood burning stove. The operation
with firewood is especially suitable for cooking and oven operation as well as
for heating the room where the appliance is installed.
It is also possible to automatically ignite the firewood by means of the pellet
burner. Just load the combustion chamber with firewood and turn on the pellet
burner.
If firewood is added to the combustion chamber while the stove is running on
pellets, the appliance recognises this and changes automatically to OPERATION
WITH FIREWOOD.
