15.1 Cleaning the Viewing Window
/ Vacuuming the Combustion
Chamber
Only clean the viewing window when it is cold!
A window coating (see Fig. 64) is normal and is
not a defect! The viewing window can be easily
cleaned with a damp cloth. Heavy soiling can be
removed with wodtke's Special Glass Cleaner. At-
tention: wodtke's Special Glass Cleaner may only
be used for cleaning the inside of the viewing win-
dow. Please observe the safety instructions on the
packaging.
Flue ash deposits in the combustion chamber (see
Fig. 65) are normal and do not negatively influence
the functionality of the furnace. Crater-like accu-
mulations of flue ash form around the burner pot,
which can be easily vacuumed away during clean-
ing / maintenance. We recommend the wodtke
Ash Box for this purpose.

Embers remaining in the ash represent a fire
hazard. Only vacuum ash into a vacuum
cleaner bag if you are absolutely certain that
there are no more embers within it.
15.2 Inspection and De-Ashing of
the Burner Pot
Please inspect the burner pot for combustion res-
idue (ash/slag) daily, but no later than after a con-
tainer filling. The cleaning/functionality limit has
been reached by 30 g ash/slag in the burner pot
(approx. 3 cm high of residue
– see image below)
and the burner pot must be cleaned.
