However, because the fuel loading chamber surfaces take little part in heat exchange
processes, this phenomenon has no significant impact on boiler operation. It is
recommended to clean those surface only during post-heating season maintenance. Clean
them as needed if inferior fuel types are used.
NOTE! Moist or thick pitch layers at the boiler fuel loading chamber inform about incorrect
and to moist fuel or incorrect boiler regulation, especially when the boiler is working under
low temperatures. It is recommended to adjust the boiler according to instructions described
in the section 11 (lighting the boiler).
14. SHUTTING THE BOILER DOWN
After a heating season and putting the boiler down (unless hot tap water is to be
provided during summer), the boiler should be cleaned carefully and all the post-burning
residues are to be removed.
Leave the boiler open to ensure its ventilation, what can prevent to avoid water
condensation at the boiler walls
15. BOILER MAINTENANCE AND REPAIRS
Periodic boiler maintenance is to be carried out once a year. Accessory should be
overhauled and maintained on an ongoing basis.
Before you overhaul the boiler and determine the scope of repairs, if any, clean the boiler
carefully from any type of residues left over from the burning process. After the end of the
heating season, when the boiler is operated properly, it may just be necessary to remove
only minor failures, which can be removed by users themselves.
Any major boiler repairs resulting from incorrect operation and failures or mechanical
damage should be carried out immediately after a need to repair is found by a competent,
qualified company or specialist.
Any leaks should be sealed by welding and damaged components are to be replaced
by new ones. In case of any difficulties, please contact the distributor or maintenance service
technician.
16. BOILER TRANSPORTATION
The boiler is delivered as an assembled unit (except for the control and blowing unit).
The boiler manual and warranty document is stored the boiler fuel loading chamber and
protected properly against damage. The boiler should be transported in a vertical position.
The boiler must not be dumped from a vehicle, but removed carefully from it. In transit the
boiler needs to be protected properly to prevent its shifting or overturning.
17. USER OBLIGATIONS
1. Only fuel with parameters described within this Operation and Maintenance Manual
can be used.
2. Make sure boiler heatable surfaces are clean, flue and chimney ducts are not choked.
3. Remove any damage and boiler components failures on an ongoing basis.
4. Make sure the water used to fill in the heating system is of proper quality.
(hardness 2°n).
5. Carry out periodic boiler overhauls and maintenance.
6. After the heating season leave the water in the boiler and the system.
7. Any boiler mechanical damage requiring welding should be carried out by a qualified
specialist.
8. Clean the fan with a soft brush once a month.
