Warning and Safety instructions
Building in
Fit wall units, cooker hood and adjacent units before fitting the gas
hob, to avoid damaging the hob.
The room in which the gas hob is
installed must be at least 20 m
size with a door or window in it which
can be opened to the outside air.
The veneer or laminate coatings of
worktops (or adjacent kitchen
units) must be treated with 100°C heatresistant adhesive which will not dissolve or distort.
Any backmoulds must be of
heat-resistant material.
Ideally the hob should be installed
with plenty of space on either side.
There may be a wall at the rear and
wall or tall units at one side. On the
other side however, no unit or divider
should stand higher than the hob.
A safety distance b of 150 mm
must be maintained between the
KM 320 G and adjacent furniture,
e.g. a tall unit, because of the heat
given off by the flames, and to allow
fumes to dissipate. There must be a
minimum safety distance of 50 mm
between the hob and a back wall.

Important
Under no circumstances should
sealant find its way between the
frame of the top part of the hob and
the worktop.
This could cause difficulties if the
hob ever needs to be taken out for
servicing, (possibly leading to damage to the frame and worktop).
The sealing strip under the edge of the
top part of the hob provides a sufficient
seal for the worktop.

Electrical connection
Electrical connection
All electrical work should be carried
out by a suitably qualified and competent person in strict accordance
with national and local safety regulations.
Installation, repairs and other work
by unqualified persons could be
dangerous. The manufacturer cannot be held responsible for unauthorised work.
Ensure power is not supplied to the
appliance while installation or repair
work is being carried out.
The appliance must only be operated when built-in. This is to ensure
that all electrical parts are shielded.
Live parts must not be exposed.
Do not connect the appliance to the
mains electricity supply by an extension lead. These do not guarantee
the required safety of the appliance.
If the socket is not accessible after installation (depending on country) an additional means of disconnection must
be provided for all poles.
For extra safety it is advisable to install
a residual current device (RCD) with a
trip current of 30 mA (in accordance
with DIN VDE 0664, VDE 0100 Section
739).
When switched off there must be an all-
pole contact gap of 3 mm in the isolator switch (including switch, fuses and
relays according to EN 60 335).
Important U.K.
This appliance is supplied for connection to a single phase 230-240 V 50 Hz
supply with a 3-core cable.
The wires in the mains lead are coloured in accordance with the following
code:
Green/yellow = earth
Blue = neutral
The voltage, rated load and fusing are
given on the data plate. Ensure that
these match the household mains supply.
Connection of this appliance should be
made via a suitable isolator (rated load
above 3 kW) or a double pole fused
spur connection unit or fused plug and
switched socket (rated load up to 3
kW) which complies with national and
local safety regulations and the on/off
switch should be easily accessible
after the appliance has been built in.
Brown = live
As the colours of the wires in the mains
lead of this appliance may not correspond with the coloured markings
identifying the terminals in your plug,
proceed as follows:
9

WARNING
THIS APPLIANCE MUST BE
EARTHED
Important
The electrical safety of this appliance
can only be guaranteed when continuity is complete between the appliance and an effective earthing system, which complies with local and
national regulations. It is most important that this basic safety requirement is
tested by a qualified electrican. The
manufacturer cannot be held responsible for the consequences of an inadequate earthing system such as an electric shock.
Non-rewireable plugs (BS 1363)
If this appliance is fitted with a nonrewireable plug, the following information applies:
If the socket outlets are not suitable for
the plug supplied with this product, it
must be cut off and an appropriate
plug fitted.
The fuse carrier and the fuse should be
removed from the old plug and disposed of. The plug cut from the flexible
cord should then be disposed of and
on no account be inserted into any
socket elsewhere in the house (electric
shock hazard).
The fuse cover must be re-fitted when
changing the fuse, and if the fuse
cover is lost, the plug must not be used
until a suitable replacement is obtained. The colour of the correct replacement cover is that of the coloured
insert in the base of the plug, or the colour that is embossed in words in the
base of the plug (as applicable to the
design of the plug fitted).
The correct fuse rating of the replacement fuses that are ASTA approved to
BS 1362 should be fitted. Replacement
fuse covers may be purchased from
your local electrical supplier, or Miele
Service agent.

The manufacturer can assume no
responsibility for damage which is
the direct or indirect result of incorrect installation or connection.
Gas connection
Connection to the gas supply, or
conversion from one type of gas to
another should only be undertaken
by an approved and registered gas
installer in strict accordance with
local and national safety regulations, (e.g. Corgi registered in the
U.K). Every appliance should have
its own isolating valve.
Gas connection
Connection
Conversion to another type of gas is described under the relevant Section.
The gas connection must be installed
so that connection can be made either
from inside or outside the kitchen unit,
and the isolating valve must be easily
accessible and visible (by opening one
of the kitchen unit doors, if necessary).
Check with your local gas supplier
about the type of gas, and compare
this information with the type of gas
quoted on the hob data plate.
The installer is responsible for ensuring that the appliance functions correctly.
The gas hob is normally suitable for
connection to either natural or liquid
gas. Check suitability in your country
with your dealer or agent.

Natural gas / liquid gas
An appropriate rigid or flexible connection and isolating valve must be
installed for final connection.
The gas connection must be so sited
that it is not adversely heated when
the appliance is in operation.
In particular ensure that hot gas exhaust cannot touch the gas hose
or appliance connections.
After installing the appliance the
gas burners have to be set for local
conditions.
When the gas hob has been installed it is essential to check that
neither the gas hose nor the electricity cable is in contact with hot
parts of the appliance or hot gas exhaust, otherwise heat damage to
the hose and cable could occur.
