3. DESCRIPTION OF THE DESIGN
NOTICE!
The boiler design is constantly improved, so there may be slight
devia
tions from this manual. It is forbidden to modify the design of the boiler on one’s
own
.

The boiler cross section is shown on Picture1. The boiler is welded from sheet steel; its
casing is coated with heat insulation material 4 and finished 5. Firegrating is cast of alloy cast
iron. Boiler heat exchanger is designed so that the heat carrier, circulating in its channels, could
as efficiently as possible assimilate heat, which is generated during the combustion process, in
different areas of the boiler.
8. DISPOSAL
The boiler package consists of: a wooden pallet, metal plate, screws and nuts,
polyethylene film, and the boiler. After unpacking the boiler, throw out the polyethylene film in the
recycling bin (save nature and sort waste - polyethylene should be classified as plastic waste).
The wooden pallet can be burned along with the boiler fuel. Metal plates, screws and nuts can be
put to the ferrous scrap.
At the end of the of the boiler service life, please give up its metal parts to the ferrous
scrap, and dispose the rest of them according to environmental requirements.
9. RISK ANALYSIS AND TROUBLESHOOTING
Problem
Cause
Action
Temperature
of
the heat carrier
above
the
allowable level
Thermostatic cooling valve has
not been installed; bottom door
is opened (automatic pressure
adjustment does not operate);
recycling
pump
does
not
operate (lost electricity)
Be sure to install the thermostatic cooling
valve into the system; close the door and
dampers, upon drop of the temperature
to an acceptable level - keep heating; the
boiler may be extinguished with sand,
earth, or other non-combustible material;
do not pour water into the chamber -
there is a high risk of burns
Condensation
Required temperature of return
water is not provided (>60°C).
No minor circuit has been
installed in the system. Wet
fuel
Install the minor circuit
– it helps to
fire the boiler to the required temperature
and reduce the condensation possibility
much faster. Use as much dry fuel
– as
possible.
Wetness
≤25%
is
recommended
The boiler is not
heated to the
required
temperature
The boiler is decaying;
Too much of the heat escapes
through the chimney
By using the draft control manual, adjust
the draft control so that the automatic
combustion process could be regularly
controlled.
6.5. FUEL
NOTICE! It is forbidden to fire fuel other than the recommended one
.
The boiler is designed to fire firewood, wooden and peat briquettes, and coal. Timber,
intended for the firewood, is to be cut and split. Wetness of the fired firewood should not exceed
20%. Firewood acquires such level of wetness during storage on a ventilated attic for 1-2 years.
Briquettes must be kept dry, otherwise they may fall apart. Firing of wet fuel reduces power output
of the boiler and increases fuel consumption, the boiler gets pitched, corrosion of the chamber
gets faster.
