3.3.1. Aeration / ventilation
A fi replace insert generates : - heating air
Heating air (convection air) is devoted to the convection of heat from the
appliance to the room. The source of heat is in the room and stays there.
Combustion air is needed to keep the combustion going by drawing in air from
the room, of directly from outside, due to the natural draught of the chimney.
• Combustion air from the living-room:
The air inlet openings are located behind the operating fl ap. When using
the appliance, please ensure there is a suffi cient supply of fresh air:
minimum 150 cm
Make sure that the ventilation supply is open; this is particularly important
with today's airtight dwellings.
If the dwelling has mechanical ventilation that creates under pressure in the
room where the appliance is located, it is necessary to fi t a fl ue gas fan.
The type of fl ue gas fan is dependent on the capacity of the mechanical
ventilation system. Always consult your fi tter about this.
In dwellings with an operating extractor hood, this should be turned to the
lowest setting or turned off altogether. If the extractor hood remains in use,
additional ventilation must be provided in compensation. This will not only
avoid poor combustion, but will also prevent fl ue gases being sucked from
the appliance into the room.
Should creating an extra ventilation opening prove insuffi cient, it is then
necessary to fi t a fl ue gas fan.
• Combustion air directly from outside:
The appliance now has a completely closed combustion system, which
allows it to operate independently of the surrounding air in the room where
the appliance is located.
