8. Boiler operation and maintenance
Use the main switch to deactivate the boiler and
wait until the boiler cools down - min. 1 hour before
maintenance (boiler cleaning).
8.A Burner operation guidelines:
Normal daily boiler operation:
³ check correct operation of system components: burner, control
system
³ check water level on a pressure gauge
³ check fuel level and quality and fuel feed system operation
³ check hydraulic joints leak tightness
³
keep the boiler room clean and tidy.
In case of any performance issues, remove the faulty devices or contact
an Authorised Service Centre to arrange a repair or an adjustment.
8.B Inspection scope and schedule
a) Monthly
³ check system water pressure
³ check safety valve operation
³ check control and safety device operation
³ check tightness of all connectors and joints
³ check balanced ventilation system
b) Minor inspection(every 6 months)
³ check rope seal and gaskets,
³ check boiler door thermal insulation,
³ check safety devices (safety valve, safety temperature limiter
STB etc.),
³ check flue gas (in case of a significant increase in flue gas tem-
perature, clean the combustion section of a boiler).
c) Major inspection(every 12 months)
³ check rope seal and gaskets,
³ check boiler door and cleanout cover thermal insulation,
³ check safety devices (safety valve, safety temperature limiter
STB etc.)
³ check flue gas
³ clean combustion section of the boiler
³ check thermal insulation of the boiler
³ check and adjust burner, adjust control system settings.
After a long boiler/burner standstill, the residual oxygen in boiler water
and the oxygen from the air mixed with a carbonic acid have highly
corrosive properties. Take any precautions necessary after a boiler
standstill for over a week.
Periodically remove the soot, sludge and ash from the combustion
chamber, the flue tubes and the grate. Clean the boiler as required, at
least every 2 weeks. Remove the ash as required.
8.C Maintenance
a) Boiler, burner, fuel feed system - mechanical
The regular and correct maintenance of the boiler is a precondition
of a correct and reliable operation and low fuel consumption of the
system. Contact an Authorised Service Centre at least once a year
and after every boiler standstill to arrange an inspection.
Heating system maintenance procedure:
³ deactivate the boiler (system) (stop mode)
³ wait for a complete stop and allow to cool
³ reduce the boiler temperature to the level allowing safe mainte-
nance
³
open boiler door
³ clean combustion chamber and all flues and check the rope se-
als in the boiler doors (replace if necessary)
³ check and clean burner (remove if necessary)–clean motor and
fan external surfaces (especially vanes)
³ close the boiler door with burner
³ remove the cover
³ clean the combustion products from the rear section of the boiler
³ check cover gasket quality (rope seals) and remove as required
³
close the rear boiler cleanout
³ check smoke duct condition and gas tightness
³ check installation and operation of the boiler sensors
³ check installation and operation of the fuel feed system
³ feeder gear motor
³ fuel feed ducts leak tightness and flow capacity
