Cleaning
In contrast to oil or gas, ash and soot are always
created when burning solid fuels. As a result, reg-
ular cleaning by the operator is required for oper-
ation without malfunctions.
Attention / Danger:
Units which are not cleaned according to our
specifications may not be operated. All war-
ranty claims are void in case of non-compli-
ance.
The number of cleanings of the burner pot /
cast grate is dependent on the ash content of
the pellets and cannot be changed by settings
on the unit, because the ash is a non-combus-
tible component of the pellets and therefore
cannot be influenced by the combustion pa-
rameters!
We therefore recommend using only wood pel-
lets with an ash content of < 0.7%.
Solid fuels create a window coating on the view-
ing window, particularly in the case of the very
fine ash of wood pellets, which can appear as
very light or dark black (especially at low output),
depending on the pellet quality and output set-
tings of the unit. This is a natural process during
the combustion of wood pellets and is not a de-
fect.
Caution!
Before beginning cleaning / maintenance
work, shut down the furnace and allow it to
cool. Please also observe the safety instruc-
tions under the container cover. All compo-
nents in the combustion chamber may still be
hot. Embers may be concealed in the ash.
Never put unburned pellets or ash from the
combustion chamber back into the storage
container
– risk of fire!

The ash drawer must be emptied no later than
when the ash is up to to the top edge of the ash
drawer.
Do not open the combustion chamber door
during operation if possible; if necessary,
open it only briefly (< 1 minute).
Viewing window
and combustion chamber door may be hot
– risk
of injury. Before opening, allow the furnace to cool
sufficiently. Use heat resistant glove.
Our tip:
place newspapers or the like in front of
the furnace before opening the doors, so that the
flue ash that falls from the doors lands on top of
them.
