Ventilation
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.
A
The combustive air must reach the burner from the
front.
The location of air inlets in relation to the high ventilation openings
shall ensure that the air is renewed in the entire volume of the boiler
room.
Please refer to the prevailing regulations in your country.
