5.3.2 Recurrent check and cleaning
The boiler must be inspected and cleaned at appropriate intervals depending on the
operating hours and fuel quality.
Depending on the activity, inspection and cleaning must be repeated after 1000
operting hours or at least every six months or no later than 2500 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.
