Cleaning
Care, inspection and maintenance
The inspection and maintenance of heating systems is
prescribed by the Energy Saving Ordinance [in Ger-
many], EN 806 and DIN 1988-8 (
8131).
Regular maintenance ensures trouble-free, energy effi-
cient and environmentally responsible heating. For
this, we strongly advise you to arrange an inspection
and maintenance contract with your heating contractor.
Boiler
Increasing boiler contamination raises the flue gas
temperature and thereby increases energy losses. As
well as observing the cleaning intervals specified, the
boiler must therefore also be thoroughly cleaned once
a year.
Information on cleaning

Hot surfaces can lead to serious injuries.
Only open the boiler after it has cooled down.
■
