Caution:
In order to avoid damage to the boiler, it is necessary to prevent the
contamination of combustion air by chlorine and/or fluoride
compounds, which are particularly corrosive.
These compounds are present, for example, in aerosol sprays,
paints, solvents, cleaning products, washing products, detergents,
glues, snow clearing salts, etc.
Therefore:
• Do not pull in air evacuated from premises using such products:
hairdressing salons, dry cleaners, industrial premises (solvents),
premises containing refrigeration systems (risk of refrigerant
leakage), etc.
• Do not stock such products close to the boilers.
If the boiler and/or peripheral equipment are corroded by such
chloride or fluoride compounds, the contractual guarantee
cannot be applied.
