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:
check correct operation of system components: burner, control
system
check water level on a pressure gauge
check fuel level and quality and fuel feed system operation
check hydraulic joints leak tightness
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
check system water pressure
check safety valve operation
check control and safety device operation
check tightness of all connectors and joints
check balanced ventilation system
b) Minor inspection(every 6 months)
check rope seal and gaskets,
check boiler door thermal insulation,
check safety devices (safety valve, safety temperature limiter
STB etc.),
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)
check rope seal and gaskets,
check boiler door and cleanout cover thermal insulation,
check safety devices (safety valve, safety temperature limiter
STB etc.)
check flue gas
clean combustion section of the boiler
check thermal insulation of the boiler
check and adjust burner, adjust control system settings.
Experts in heating
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:
deactivate the boiler (system) (stop mode)
wait for a complete stop and allow to cool
reduce the boiler temperature to the level allowing safe mainte-
nance
open boiler door
clean combustion chamber and all flues and check the rope se-
als in the boiler doors (replace if necessary)
check and clean burner (remove if necessary)–clean motor and
fan external surfaces (especially vanes)
close the boiler door with burner
remove the cover
clean the combustion products from the rear section of the boiler
check cover gasket quality (rope seals) and remove as required
close the rear boiler cleanout
check smoke duct condition and gas tightness
check installation and operation of the boiler sensors
check installation and operation of the fuel feed system
feeder gear motor
fuel feed ducts leak tightness and flow capacity
