21.2 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 cleaned if necessary. To clean the flue pipes remove the heat-resisting stones
from the combustion chamber in the order shown. Any soot or dust residue can be brushed
off and vacuumed. Replace the heat-resisting stones in reverse order.
[fig. 6]
Use a flexible pipe brush to clean the flue pipe at the cleaning port located on the flue pipe.
From time to time, the handling shaft should be greased (grease available at your Hase
specialist dealer).

21.3 Ceramic Glass Panels and Windows
When the stove is properly operated, the secondary air simultaneously forms an air curtain
at the pane, which prevents the glass from becoming sooty.
If ash particles get on the ceramic glass panels, we recommend, as an alternative
to conventional glass cleaners, a tried and true environmentally-friendly cleaning
method:
Take some balled-up paper towelling or newspaper, moisten it, dip it into the
cold wood ash, rub the panel with it and then wipe the glass with a clean, dry
ball of paper.
21.4 Fire Box Lining
The heat-resisting stones in your stove‘s fire box are made of Vermiculite. Vermiculite is
a fire-resistant mineralogical granulate material with excellent insulating properties. The
density of the stones is a result of the optimal balance between mechanical stability and
insulation properties.
The relatively soft surface is subject to natural wear and tear, depending on use. The heat-
resisting stones 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 stones do
not impair the functioning of your stove.
To reduce the damage to the heat-resisting stones, place logs carefully in the fire
box and do not let them fall against the walls of the fire box.
