16.2 Flue Gas Paths
The stove and flue pipes should be inspected for
sediment and deposits at the end of each year’s
heating period (even more often if required, e.g. after
the chimney has been cleaned), and then cleaned if
necessary.
To clean the flue-gas channels remove the upper
heat-resisting slab and the deflectors, if present
(see Instructions for Installation and Maintenance).
Any soot and dust deposits can be brushed off and
vacuumed. After cleaning, re-assemble the parts
removed.
NOTE!
Use a flexible pipe brush to clean the flue
pipe at the cleaning port located on the flue
pipe.
16.3 Ceramic Glass Panels
and Windows
When the stove is properly operated, the secondary
air forms an air curtain at the pane, which minimises
the formation of soot on the glass.
However if ash particles settle on the ceramic glass
pane, we recommend that you use a reliable and en-
vironmentally friendly cleaning process:
Ball some up paper towels or newspaper, moisten
the ball, dip it into the cold wood ash, rub the panel
with it and then wipe the glass with a clean, dry ball
of paper.
NOTE!
Only use wood ash from split logs for this
cleaning process. Wood briquettes can
contain additives, which may scratch the
surface of the ceramic glass.
A common, retail glass detergent may also be used
for cleaning. When cleaning the seal and steel sur-
faces we recommend that you spray the glass deter-
gent on a cloth and not directly on the pane.
16.4 Fire Box Lining
The heat-resisting slabs in the fire box of your stove
are made of vermiculite. Vermiculite is a fire-resi-
stant mineralogical granulate material with excellent
insulating properties. The density of the slabs arises
from the optimal balance between mechanical stabi-
lity and insulation properties. The relatively soft sur-
face is subject to natural wear and tear, depending
on use. The heat-resisting slabs have to be replaced
if parts break off and the back wall of the fire box,
located behind the slabs, becomes visible. Tears or
cracks in the heat-resisting slabs do not impair the
functioning of your stove.
NOTE!
To prevent damaging the heat-resisting
slabs, place logs carefully in the fire box
and do not let them fall against the walls
of the fire box.
16.5 Sealing Strips
The sealing strips are made of highly heat-resistant,
asbestos-free fibreglass. The sealing strips are wea-
ring parts and thus have to be replaced in line with
the frequency of use.
We advise having your stove regularly inspected by
a specialist.
