Warning and Safety instructions
Using at the same time as another heating appliance that depends on the air
from the room
 Danger of toxic fumes!
Great care should be taken when using the cooker hood in the
same room or the same area of the house at the same time as
another heating appliance that depends on the air from the room.
Such heating appliances draw in air from the room and duct
exhaust gases out to the open air through a chimney or extraction
ducting. They include gas, oil, wood and coal-fired boilers and
heaters, continuous flow or other water heaters, gas hobs and
ovens.
The cooker hood draws in air from the kitchen and from
neighbouring rooms. This applies to the following modes of
operation:
- extraction mode,
- extraction mode with an external motor,
- recirculation mode with a recirculation box installed outside the
room.
If there is insufficient air, an underpressure will occur. The heating
appliance may be starved of oxygen. This impairs combustion.
Harmful gases could be drawn from the chimney or extraction
ducting back into the room.
Risk of death!
