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
4
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.
n Type C - Forced flue version
If the evacuation of combusted gases and the intake of combustive
air are done using a concentric conduit, ventilation of the boiler room
is not necessary.
Condensing boilers require a flue gas discharge system or a fresh air
inlet specially adapted to the method of operation. Installation must
be carried out in accordance with current laws.
CAUTION
Do not block the air inlet, combustion product evacuation
or condensation water flow pipes (even partially).
Avoid any low points in the flue gas and condensates
discharge circuit in order to prevent any condensates
accumulation.
n Type B - Open flue
Condensing boilers require a flue gas discharge system or a fresh air
inlet specially adapted to the method of operation. Installation must
be carried out in accordance with current laws.
Position the air inlets in relation to the high ventilation vents in order
that the air is refreshed throughout the boiler room.
CAUTION
Avoid any low points in the flue gas and condensates
4
discharge circuit in order to prevent any condensates
accumulation.
Do not block the air inlets in the room or the
4
combustion products evacuation or condensation
water flow pipes (even partially).
