8 . Boiler operation and m aintenance | 9 . I m portant notes
CAUTION!
The fl ue and ventilation ducts require periodical
inspection and cleaning (at least once a year) by
an authorised company.
An effi cient ventilation and fl ue system is required for
the correct and safe boiler (heating system) operation.
The maintenance and operation of the fl ue ducts are
covered by the following regulations:
• Act of 24 August 1991 on fi re safety (Polish Journal
of Laws Dz. U. No. 81 as amended);
• Act of 11 June 2006 on fi re safety of buildings, other
facilities and land (Dz. U. No. 80/06).
b) Boiler and accessories wiring system
• check wiring system in accordance with good engineering
practices
• check cables, plugs and connections
• check boiler control system connections and functions
• check boiler pump and mixing valve operation
• check operation of other devices in the boiler room
(circulation pumps, fi lters, sludge fi lters, valve etc.)
c) Storage hopper
Empty the storage hopper before maintenance and inspections.
• check the condition and functioning of the Platinum Bio
swivel chute with fuel storage hopper
• check storage hopper for rigidity and leak tightness
• check storage hopper top cover tightness
• check storage hopper outlet for blockage
d) Final boiler room inspection
• fi ll the storage hopper with fuel
• start the boiler
• check correct operation of the entire heating system
• check (fl ue gas analysis) and adjust the heating system
(control system settings, burner settings etc.)
9. Important notes, guidelines
and tips
Before burner start-up check water level in the heating system.
Fuel storage hopper must be fi lled with fuel to a required level
to guarantee reliable boiler operation.
CAUTION!
Using fuel with different specifi cations may affect
device operation and cause damage. Fuel with foreign
material (e.g. stones) is treated as unsuitable for pellet
burners. The manufacturer shall not be held liable
for any damage caused by using fuel with different
specifi cations.
Use safety gloves as a protection against burns and
follow safe operation guidelines to ensures safe
maintenance.
The heat exchanging surfaces are contaminated during
operation resulting in an increase in temperature at the fl ue
gas outlet and reduced effi ciency.
CAUTION!
The device has to be installed and commissioned
by a company authorized by the manufacturer, otherwise
it may invalidate the warranty.
Do not open the doors and covers while the boiler is operating
(burn hazard). Do not open the doors during fuel ignition
(explosion hazard). Do not use starters and fl ammable
materials to light a fi re. Do not store fl ammable materials near
the boiler or the burner.
Keep the minimum return temperature (60°C) to ensure correct
boiler operation – risk of fl ue gas water condensation. Some
condensate may occur during start-up (heating).
After the heating season, thoroughly clean the boiler and the
fl ue ducts.
Keep the boiler room clean and dry.
