7 Maintenance
Inspection and maintenance
The operator is responsible for the safety and environmental compatibility of the
heating system (see local regulations).
It is therefore recommended to sign a maintenance and inspection contract with a
trained and certified heating contractor that provides annual inspection and
maintenance. This ensures high efficiency and environmentally compatible
combustion.
Cleaning the outside of the boiler and the control unit
Wipe down with a damp cloth. Do not use any abrasive or corrosive cleaning agents.

objectives for us. Environmental protection laws and regulations are strictly adhered
to.

into account economic points of view.
Packaging method

guarantee optimal recycling.
