Aeration
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.
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 suck 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.
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).
The minimum cross sections and the emplacement of the fresh air
inlet and the air discharge are governed by the order of 21/03/1968
amended by the orders of 26/02/1974 and 03/03/1976.
Generator installed in a building for collective use
(installations less than 70 kW)
The fresh air inlet must:
- Come out in the lower section of the premises,
- Have a free minimum cross section calculated on the basis of 0.03
dm² per kilowatt installed output and at least equal to 2.5 dm².
The air discharge must:
- Be located in the upper section of the premises,
- Rise above the roof (unless using an equivalent system which
does not cause a nuisance to neighbours),
- Have a free cross section (corresponding to 2/3 of that of the air
inlet and at least equal to 2.5 dm²).
Generator installed in a builing for individual use
An adequate supply of fresh air must be provided as close as
possible to the appliances. Its cross section must be at least 0.5
dm².
In the upper section of the premises, an air outlet must ensure
effective ventilation.
