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.

Construction of a KLIMOSZ DUOPELET boiler
The KLIMOSZ DUOPELET automatic boiler is not maintenance-free and requires the user to carry out
some periodic maintenance activities; 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 working.
The main part of the boiler is a steel heat exchanger, made from 6-8mm internal sheet and 4mm external
sheet. KLIMOSZ DUO PELLES NG 15 ÷ 75 boilers can be installed in a closed system. KLIMOSZ DUO
PELLES NG 100 ÷ 150 and KLIMOSZ DUOPELET B 15 ÷ 35 boilers can be installed only in a open system. In
the lower chamber there is situated the automatic burner to combust pellets. In the automatic mode there is an
automatic ignition. After the ignition module thanks to the ventilator, automatic cleaning is activated. Below the
combustion chamber there is an ash tray situated.
Next to the boiler, there is a fuel storage bin with a feeder screw at the bottom. The fan which provides air
for combustion is situated below the automatic burner. The amount of air for combustion can be regulated by
changing the fan rotation speed on the boiler regulator (recommended) or by manual setting of the choking flap on
the fan.
The heating water inlet is situated on the back wall of the exchanger, in its bottom middle; the water outlet
is situated on the top left and right. In the back of the boiler there is a smoke conduit, which carries flue gas to the
chimney. The steel exchanger, its cover as well as lower and upper door, are covered with mineral insulation,
which reduces heat loss during combustion. The steel casing is protected with high quality powder paint.
Boiler is prepared t ochange the side of the fuel tank and the burner. Doors also can be opened on both
sides.

Construction of a KLIMOSZ UNI PELLETS boiler
The KLIMOSZ UNIPELET automatic boiler is not maintenance-free and requires the user to carry out
some periodic maintenance activities; 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 working.
The boiler drum consists of sections with the help of pressured boiler nipples and is secured with boiler screws.
The sections create burning and ash space, water space and a convective part. Heat water input and output are
situated at the back part of the furnace.
The back section of the furnace has a smoky chimney – pot and a heat water flange in the upper part, and a
returnable water flange with a socket for impregnating and clearing plug. Stoker and ash door and a firebox door
under them are fixed to the front section.
The whole boiler drum is isolated with a stifling, mineral isolation that reduces losses by sharing heat into the
surroundings. The steel jacket is fitted in colour with a quality comaxite paint

Hand-fired furnace of the KLIMOSZ DUOPELET boiler
The KLIMOSZ DUOPELET boiler provides the possibility for burning solid fuels in the traditional
mode. After manual loading, wood and coal, as substitute fuel, can be burnt in the upper part of the exchanger,
called the "upper combustion chamber".
The upper combustion chamber is an emergency chamber, in which
burning throughout the heating season is not recommended due to the lower power capacity achieved as compared
to the maximum power capacity of the boiler. For burning in the upper chamber to run properly, some conditions
for chimney draught have to be met
