IMPORTANT SAFETY INSTRUCTIONS

An insufficient safety distance between the cooktop and the
ventilation hood can result in damage to the ventilation hood.
The minimum safety distances between the top of the cooktop and
the bottom of the ventilation hood given in the "Installation" section
of this manual must be observed, unless the cooktop manufacturer
states that a greater safety distance is required.
If more than one cooking appliance is installed beneath the
ventilation hood, and they have different minimum safety distances
to the ventilation hood, select the greater distance.

The information provided in "Installation" must be observed when
installing the ventilation hood.

Components can have sharp edges which may cause injury.
Wear gloves to protect your hands.

When installing the exhaust duct, only use pipes or tubes made of
non-flammable material. These can be obtained from your Miele
dealer or from Miele Technical Service. Always observe local building
code requirements when selecting duct material.

Exhaust air should not be vented into a chimney or vent flue which
is otherwise in use and should not be channeled into ducting which
ventilates rooms with fuel-burning installations.

If exhaust air is to be extracted into a chimney or ventilation duct
no longer used for other purposes, seek professional advice.

WARNING: TO REDUCE THE RISK OF FIRE USE ONLY METAL
DUCTWORK.
