27.2 Flue Gas Paths
The stove and fl ue 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 fl ue-gas channels remove the upper heat-
resisting slab and the defl ectors, 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 fl exible pipe brush to clean the fl ue pipe
at the cleaning port located on the fl ue pipe.
27.3 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.
If ash particles get on the ceramic glass panels, we recom-
mend a tried and true environmentally-friendly cleaning
method as an alternative to conventional glass cleaners:
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.
27.4 Fire Box Lining
The heat-resisting slabs in the fi re box of your Ottawa stove are
made of Vermiculite. Vermiculite is a fi re-resistant mineralogi-
cal granulate material with excellent insulating properties. The
density of the slabs arises from 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 slabs have to be replaced if parts break
off and the back wall of the fi re 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 fi re box and do not
let them fall against the walls of the fi re box.
27.5 Sealing Strips
The sealing strips are made of highly heat-resistant, asbestos-
free fi breglass. The sealing strips are wearing parts and thus
have to be replaced in line with the frequency of use.
We advise having your stove regularly inspected by a
specialist.
