ATTENTION!!! The KLIMOSZ heating boilers are not intended for burning waste and no substances other
than those recommended by the manufacturer can be burnt in them.

**) Sawdust granulate (pellets) should be at least hard enough for it to be impossible to crush
a few fuel granules in a clenched fist, preventing the feeder from getting jammed. Light colour grades are
recommended, without bark, which can cause deposit formation in the burner.

ATTENTION!!! MOISTURE CONTENT IN FUEL MUST NOT EXCEED 15%. USING MOIST FUEL
RESULTS IN A CONSIDERABLE REDUCTION IN THE BOILER'S POWER CAPACITY (EVEN BY AS
MUCH AS 50%) AND REDUCTION IN THE LIFE-SPAN OF THOSE PARTS OF THE BOILER WHICH ARE
IN CONTACT WITH MOIST FUEL. USING IMPROPER QUALITY OR MOIST FUEL RESULTS IN LOSING
WARRANTY RIGHTS WITH RESPECT TO THE PARTS EXPOSED TO CONTACT WITH SUCH FUEL.
3. Construction of the KLIMOSZ COMBI, KLIMOSZ COMBI B boiler
The KLIMOSZ COMBI and KLIMOSZ COMBI B automatic boiler is not maintenance-free; it is
therefore recommended that the user should carefully read the principles of its operation, regulation and
maintenance in order to avoid any problems related to its work. Construction of the KLIMOSZ COMBI boiler
makes it possible to use solid fuels in the automatic or traditional mode as well as to use liquid fuels. The boiler
has been constructed on the base of a cast-iron exchanger of the multi-purpose VIADRUS U22 boiler. The castiron part of the boiler, which is called the upper combustion chamber, can be used for burning coal, coke or wood
as substitute fuel after manual fuel loading. KLIMOSZ COMBI boilers can be installed in a closed system up to
working pressure 4,0 bar.
Under the water grate of the boiler heat exchanger of a U22 boiler, there is an added steel combustion
chamber, with (W version) or without (S version) a water jacket. There are the following cast-iron parts in the
