Inspection and maintenance
Heating systems should be regularly maintained for the
following reasons:
• to achieve a high level of efficiency and to operate the
system economically (low fuel consumption),
• to achieve a high level of operational safety,
• to maintain the cleanest combustion.
B Recommendation for customers: Sign a
maintenance and inspection contract with a trained
and certified contractor, covering an annual inspection
and demand-dependent maintenance.
B The operator is responsible for the general and
environmental safety of the heating system.

thinners, paints etc.) near the appliance.
Combustion air/room air
B Keep the supply of combustion/room air free of
corrosive substances (e.g. halogenated hydrocarbons
that contain chlorine or fluorine compounds). This will
help prevent corrosion.
