4.3.3

Ventilation

To allow the input of combustive air, sufficient ventilation must be
provided in the boiler room, for which the cross section and
emplacement must satisfy regulations in force in the country in which
the boiler is installed.
Position the air inlets in relation to the high ventilation vents in order
that the air is refreshed throughout the boiler room.
Do not obstruct the air inlets in the room (even partially).
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.
