• check the 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.
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 temperature,
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.),

Experts in biomass heating
After long boiler downtime, the residual oxygen in boiler water and the
oxygen from the air mixed with carbonic acid have highly corrosive properties.
Take any precautions necessary if the boiler downtime is to exceed a week.
Periodically remove soot, sludge and ash from the combustion chamber, flue
tubes and the grate.
Clean the boiler as required, at least every 2 weeks. Remove ash as required.
c. Boiler, burner, fuel feed system - maintenance.
Regular and correct maintenance of the boiler is essential for the 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 downtime
to arrange an inspection.
Heating system maintenance procedure:
• deactivate the boiler (system) (stop mode)
• wait for a complete stop and allow to cool
• allow to cool until safe maintenance is possible
• open boiler door
• clean combustion chamber and all flues and check the rope seals in the
boiler doors (replace if necessary)
• check and clean the burner (remove if necessary) – also, clean the motor
and fan (especially vanes) from the outside
• close the boiler door with burner in place
• remove the cover
• clean the combustion products from the rear section of the boiler
• check cover gasket quality (rope seals) and remove as required
• check smoke duct condition and gas tightness
• check installation and operation of the boiler sensors
• check installation and operation of the fuel feed system
• fuel feed ducts leak tightness and flow capacity
