TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
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 ceramic nozzles and
the boiler as a whole. Regular cleaning
is important to ensure the optimal
performance and long operational life of
the boiler.
We recommend cleaning of the ash
container in 3 to 5 days interval in
accordance with the fuel used
If needed, clean the ash in the flue pipes.
Use the paddle
Warning! It is possible presence of
smoldering coals. Dispose the ash only in
specific adopted for this purpose places.
It can cause a fire in garbage container.
9.3.1. Preparation for new heating
season. Recommended procedures for
boiler’s maintenance.
1.
Dispatch the internal safety doors in the
boiler’s combustion chamber. Clean the
boiler’s combustion chamber with metal
brush from the set. Remove the tar and
soot. They cause non-effective heating.
2.
Clean well water ribs. Remove
accumulated ash and soot by using the
paddle and the brush from the set.
3.
Remove the inspection lid under
the boiler’s chimney and clean the
accumulated ash in it.
Attention! Replace the gasket of
the inspection lid with a new one
if damaged.
4.
Clean well the metal grate at the boiler’s
bottom. Check if the gaps between
the smoke tubes are well cleaned. The
presence of tar or inflammable materials
in the combustion chamber of the boiler
cause non-effective heating.
5.
Check door tightness:
- Open boiler doors.
- Place paper strips on the four sides of
the doors and close leaving part of the
strips protruding outside.
- Pull the paper strips. If the strips tear
upon pulling, doors seal tightly.
If regulating of the boiler’s doors or is
needed or insulation rope replacement
must be done, please contact your
installer.
9.4. Important recommendations for
long-lasting and correct operation of the
boiler.
9.4.1
. Please
perform
periodic
maintenance of the boiler as described in
instructions, section 9.3.1.
9.4.2.
The allowed moisture content of
the fuel used must not exceed 15% ÷ 20%.
9.4.3.
Gas emission in the combustion
chamber may result in the formation of
tar and condensate (acids). Therefore,
a mixing valve must be installed and it
must be adjusted so that the minimum
temperature of the water returning in
the boiler is 65° С. This extends the life
