4 GENERAL NOTES ON ASSEMBLY AND
COMMISSIONING
The KSO (Kleinspeicherofen) stove kit allows for setting up a small accumulation stove with a clearly defined
and approved firebox.
The KSO can be arranged with different cladding materials. Please note, that the information given in techni-
cal data depends on the choice of cladding materials. The combustion chamber and the top-mount heat ac-
cumulator are always round in shape, regardless of the form of external casing.
This manual describes the assembly of the base frame, the combustion chamber and the top-mount accu-
mulator, and the stove front with stove door as well. The instructions for assembly of the stove casing and
the door frame or mounting frame are included in the corresponding packaging units.
For stove casing assembly you will need a pedestal ring that comes with the casing, however, it must be
already mounted before the base frame is positioned on it. Different pedestal rings are used for different
cladding materials (thermal concrete, tiles, clay,...), which are distinguished by different external diameter
and height setting.
The combustion chamber and the top-mount heat accumulator are designed as double shell structures. The
inner shell is in direct contact with fire and/or hot combustion gases. This layer is assembled dry without ad-
ditional assembly materials. The tightness of the external shell is essential for the accumulation stove func-
tion. Therefore, all components of the external casing must be tightened with the attached high-temperature
sealant, in addition to the pre-assembled sealing ropes. It must be applied on all external joints, even on the
adjoining faces of stove front and smoke outlet.
During assembly, all contact faces of components must be kept clean and free from dust to ensure accurate
fit and tightness.
After assembly of base frame and combustion chamber we recommend to start with the casing assembly,
and in the area of top-mount accumulator, set first the accumulator parts layer by layer, while setting the cor-
responding casing ring at the same time.
Cleaning of top-mount accumulator is possible only from the top - after removal of “external top cover” and
“internal top cover” parts. Therefore, the corresponding casing parts (top cover), and with vertical smoke out-
let - the smoke pipe connecting piece, must be removable.
The individual parts are reinforced with steel needles. These can protrude on edges and breaking points!
Risk of injury!
Wear protective gloves during assembly of KSO!
Please observe the warning label on the high-temperature sealant!
