OPERATING MODES

You can use this appliance in the air extraction or the
recirculation mode.
NOTE: All openings in ceiling and wall where the hood will
be installed must be sealed.

Fan operation

The air that is drawn in is cleaned by
the grease fi lters and exhausted outdoors
by a ductwork.
NOTE: Ventilation may not exit through an already
operational smoke or exhaust chimney, nor a duct used
for ventilating furnace installation areas.
If the ventilation is intended to pass through a
•
smoke or exhaust chimney that is not in operation,
the responsible area heating inspector must give
approval.
If the ventilation passes through an external wall, use
•
a telescopic wall sleeve.

Recirculating mode

The air that is drawn in is cleaned by the
grease fi lters and activated carbon fi lters
and returned back into the kitchen.
WARNING
Improper installation of gas appliances and ventilation hoods
can create a risk for carbon monoxide which can be harmful.
To reduce the risk of carbon monoxide poisoning, ensure
the gas appliance is properly installed according to the
manufacturer's instructions, as well as ensuring the hood is
vented to the outside for proper exhausting of gases or fumes.
Refer to local building codes for latest requirements and
restrictions when installing ventilation products in recirculation mode.
