a Caution!

boiler must be operated independently of the
ventilation!

When choosing the installation site and while operating
the boiler, make sure that the combustion air is
technically free of chemical substances containing
fluorine, chlorine, sulphur etc. Sprays, solvents and
cleaning agents, paints, adhesives etc. contain these
kinds of substances, which in the worst case can lead to
corrosion, also in the flue system, during ambient air
dependent operating of the boiler.
The boiler must be operated independently of the
ambient air, particularly in hairdressing salons,
carpenter's shops, or paint shops and cleaning
companies. Otherwise, a separate installation room is
required to guarantee that the combustion air supply is
technically free of the substances mentioned above.
