Important safety instructions
 Warning: When used for extraction, refer to the
national regulations for building ventilation systems.
Do not connect the exhaust pipe to a VMC type
ventilation system, to a flue (chimney, boiler, ...).
Also check the absence of disruption with the
ventilation of the room when there are gas
appliances (water heater, gas cooker, ...). If in
doubt, use the hood in recycling mode.
 Proper ventilation of the room must be provided
when the hood is used simultaneously with
appliances using gas or other fuel.
 The air must not be vented through a duct that is
used to vent flue gases from appliances burning gas
or other fuels. The rules regarding the evacuation
of the air must be respected.
