a a) Ash sweeping of the burning chamber, checking of the primary air exits
Ash sweeping of the burning chamber (do not let it build up in the corners) is done when the
layer of ash reaches 3 to 5 cm. An ash sweeping may of course be done earlier. The quantity
of ash produced depends on the type of wood used, its age, its general quality, its moisture
content, of the consummation. A bad combustion produces a large buildup of ash and tar
(see 1.4). It is necessary 2 to 3 times per year to take out the hanging plates from the
burning chamber before sweeping at the sides and cleaning out the air passages. Neglected
maintenance can provoke premature wear and tear of ceramic, irreparable deformation of
the hanging plates, a premature wear and tear of the tunnel, an excessive clogging up.
b) Ash sweeping of the tunnel
The ash sweeping of the tunnel must be done regularly (daily in winter): it must not be
obstructed by ash in order that the combustion can take place normally and the tunnel does
not overheat. Neglected maintenance can provoke irreparable deformation and a premature
wear and tear of the tunnel.
Do not remove the ceramics
for cleaning !!
Daily cleaning of the tunnel
Particular attention must be
given to cleaning the back
and front corners.
