Warning and Safety instructions
Building in
Fit wall units and the cooker hood
before fitting the appliance, to avoid
damaging it.
As a minimum 20 m3 space is
required where the appliance is
installed, and a door or window 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 heat
resistant adhesive which will not
dissolve or distort.
The worktop upstand must be heat
resistant.
recommended
Ideally the hobs should be installed
with plenty of space on either side.
There may by a wall at the rear and a
wall or tall units at one side. On the
other side, however, no unit or divider
should stand higher than the hob.
Due to the heat radiated by the hob
and to allow cooking fumes to
dissipate it is essential that a
minimum safety distance a is
maintained between the worktop
cut-out and adjacent kitchen units,
e.g. a tall unit, as follows:
100 mm with KM 404 / KM 405
250 mm with KM 406
200 mm with KM 414 / KM 417
There must be a minimum safety
distance of 50 mm between the
appliance and a back wall.
not recommended
not allowed
4
Warning and Safety instructions
The gas hob must not be installed
next to an electric fryer, as the gas
flames could ignite fat in the fryer. It is
essential to maintain a minimum
distance of 288 mm between these two
appliances.
Safety distance above appliances
A hob may not be built in over a
washing machine, tumble dryer,
dishwasher, fridge, fridge-freezer or
freezer. The high radiant temperatures
which are sometimes generated by the
hob could damage such appliances.
This equipment is not designed for
maritime use or for use in mobile
installations such as caravans, aircraft
etc. However it may be suitable for
such usage subject to a risk
assessment of the installation being
carried out by a suitably qualified
engineer.
A minimum safety distance b must be
maintained between the hob and the
cooker hood above it. See the
manufacturer’s operating and
installation instructions for details. For
any flammable objects, e.g utensil rails,
wall units etc. a minimum safety
distance of at least 760 mm should be
maintained between it and the hob
below.
When two or more appliances are
installed together below a cooker
hood, e.g. a ceramic combiset and
a gas wok combiset, which have
different safety distances given in
their installation instructions you
should select the greater distance of
the two.
All dimensions in this instruction booklet
are given in mm.
Keep these instructions in a safe place
and pass them on to any future owner
of the appliance.

Safety clearance
Before installing the appliance check that the location provides the required
clearances from combustible materials and if necessary provide protection to
adjacent surfaces as required by regulations.
Shown area indicates protected surface, which may be ceramic tiles or other
approved material.
If clearance between side and rear walls and the periphery of the burner is less
than 200 mm, the walls must be protected with a non-combustible material. The
protection must be extended a minimum distance of 150 mm above the burner
(refer - gas fitting regulations).

General
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.
21
Electrical connection
Important
All electrical work should be carried
out by a suitably qualified and
competent person in strict
accordance with national and local
safety regulations.
For extra safety it is advisable to install
a residual current device (RCD), with a
trip current of 30 mA.
Connection for each appliance should
be made via a suitable isolator.
The data plate gives the necessary
data for connection.
WARNING
THIS APPLIANCE MUST BE
EARTHED
The wires in the mains lead are
coloured in accordance with the
following code:
Green/yellow = earth
Blue
= neutral
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:
– The wire which is coloured green
and yellow must be connected to the
terminal in the plug which is marked
with the letter E or by the earth
symbol - or coloured green or
green and yellow.
– The wire which is coloured blue must
be connected to the terminal which
is marked with the letter N or
coloured black.
– The wire which is coloured brown
must be connected to the terminal
which is marked with the letter A or
coloured red.
22
Gas connection
Connection to the gas supply, or
conversion from one type of gas to
another should only be undertaken by
an approved fitter, who is responsible
for correct functioning of the appliance
when installed. Every appliance should
have its own isolating valve.
Check with your local gas supplier
about the type of gas and its
calorific value, and compare this
information with the type of gas
quoted on the hob data plate.
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).
The gas hob is normally suitable for
connection to either natural or liquid
gas. Check suitability in your country
with your dealer or agent.
The hob is supplied ready for
connection to natural gas.
A set of jets for conversion to liquid gas
is included with the hob.
23
Gas connection
Natural gas / liquid gas
The gas connection must be in
accordance with national and local
regulations.
The relevant building regulations
must also be observed.
KM 404 / KM 405 / KM 406
The gas connection must be so sited
that it is not adversely heated when the
appliance is in operation.
Pressure Test Point.This is provided on
the gas regulator (supplied for natural
gas).
^ Loosen the screw in the test point
until it is free in its housing. The
screw is retained in this position.
^ Connect the hose from the pressure
gauge.
^ Reassemble one of the large burners,
turn on the gas and manually light the
burners.
Gas pressure must be set by the
approved gas fitter as shown on the
data plate:
KM 414 / KM 417
Natural gas
1.00 kPa
ULPG (Propane/Butane)
2.75 kPa
^ Disconnect gauge and screw in the
test point screw.
When the gas hob has been
installed it is essential to check that
neither the gas pipe nor the
electricity cable is in contact with hot
parts of the appliance or hot gas
exhaust.
A full operational test and a test for
possible leakages must be carried
out by the fitter after installation.
