Problem Prevention
Possible installation
damage due to
strains in the
material caused
by temperature
differences
Fill the heating installation
only in cold conditions (inlet
temperature must not exceed
40°C).
Danger of
installation
damage due to
accumulation
of deposits.
Condensate
formation and
tar deposits may
shorten boiler’s
operational life.
- Do not operate the heating
boiler for a long period of time
in partial load mode
- The temperature at the
boiler inlet must not be
less than 65°C, boiler water
temperature must be between
80°C and 85°C.
- Use the boiler for a short
period to heat warm water in
the summer.
9. BOILER OPERATION
9.1. Loading and ignition the boiler
When ignition the boiler for the first time, a
condensate is formed which is later drained (this is
not a fault in the boiler).
Fuel is loaded in the combustion chamber and it is
recommended to load logs of length equal to the
combustion chamber length and stack them tight
inside with least possible air gaps. The chamber door
as well as all inspection openings must be closed
and sealed. Open the thermostatic draft regulator
and chimney flap to ignite the boiler. When boiler
temperature reach 85°С, adjust intake air by the
chimney flap and boiler air-intake door flap. The
position of boiler air-intake door flap adjust by
thermostatic draft regulator.
When burning wood with moisture content more
than 20%, results in:
- significantly increases fuel consumption;
- not reach the desired power;
- lifetime of the boiler and chimney fall.
*
Maintain operating temperature between
65° C and 85° C.
9.2. Adjust the boiler combustion by thermostatic
draft regulator
Adjusting. Heat the boiler up to 80°С. Control valve is
placed in a position to meet the temperature reading
on the thermometer. Red numbers and red indicator
point are valid for vertical mounting.
Thermostatic regulator test. Through the control
valve set temperature reading of thermometer in the
boiler. The flap must be close whet the temperature
reach 95°С.
9.3. Cleaning of the boiler
*
Caution! Hot surfaces.
Before cleaning the boiler, make sure the
fire in it has died out and the boiler has
cooled down.
Boiler cleaning must be carried out periodically and
adequately every 3 to 5 days. Ash accumulated in
the combustion chamber, condensed moisture and
tar deposits significantly reduce the life span and
performance of the boiler and result in deterioration
of the properties of the heat exchange surface In case
of larger ash accumulation there is not enough space
for fuel combustion which may result in damage of
the boiler as a whole. Regular cleaning is important
to ensure the optimal performance and long
operational life of the boiler. At the start of the new
heating season is recommended cleaning the boiler
by a competent service.
It is recommended that the ash-and soot-container
be emptied and cleaned every 3 to 5 days depending
on fuel used.
Scrape the inside of flue pipes if necessary. Use the
scraper tool.
*
Caution! Ashes may contain smoldering
charcoal. Dispose of ashes only in specially
designated facilities. Disposing of ashes into
public garbage containers may cause fire.
9.3.1. Preparing for the new heating season.
Recommended boiler maintenance procedures:
1. Remove internal safety gates inside the boiler
firebox (combustion chamber). Scrape thoroughly
the firebox using the scraper brush from the boiler
cleaning kit. Remove tar and soot deposits as they
obstruct normal heat radiation.
2. Clean thoroughly water jacket ribs. Remove cinder
and soot deposits using the scraper tool and brush
from cleaning kit.
3. Remove inspection opening lid below the boiler
flue opening and remove ash deposits in there.
*
Caution! Replace inspection opening lid
gasket wth a new item if its integrity is
broken.
4. Clean well metal grill in the bottom part of the
boiler. Check whether gaps between flue pipes
are well cleaned. Tar deposits or residues of non-
combustive materials inside the boiler firebox
deteriorate normal combustion process.

If necessary, adjustment of of boiler doors
or replacing insulation rope, please contact
in your installer.
