Burning chamber
Expansion cracks at insulating plates,
respectively burning chamber stones,
don´t affect their capacities and don´t
represent warranty claim.
During cleaning ensure that the slot
between the burner plates is not clogged
(see picture below).On the burner plates
themselves, an ash layer of about 5 cm
can be left which is provided for glow
sustainment.
Attention:
The combustion chamber must always
be cleaned last, as the ash may fall in the
burn-off areas when cleaning the heat
exchanger pipes.
