The boiler must be inspected and cleaned at appropriate intervals depending on the
operating hours and fuel quality.
Inspection and cleaning must be repeated after not more than 1500 operating hours or
at least once a year. For less efficient fuels (e.g. high ash content) this work needs to
be carried out more frequently.
If the system is only fired with pellets, the interval can be increased to 2000 operating
hours (or at least once a year).
❒ Open the fuel loading door and clean the carbonisation gas duct with a small
brush
❒ Open the fuel loading door and unhinge the cladding plates
❒ Check the primary air openings (A) inside the boiler for unobstructed air flow and
clean if necessary
