Warning and Safety Instructions

Warning and Safety Instructions

Building in

To avoid damage to the hob install
it after fitting any wall cabinets

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.
Any backmoulds must be of heat-resis­tant material.

Ideally the hobs 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 must be main­tained between the hob and ad­jacent furniture, because of the heat
given off by the flames, and to allow
fumes to dissipate; with a tall unit
for example at least
100 mm with KM 404.

The gas hob must not be installed next
to an electric deep fat fryer, as the gas
flames could ignite the fat in the fryer.
It is essential to maintain a distance of
at least 288 mm between these two ap­pliances.

The hob must not be installed over a
dishwasher, washing machine, tumble
dryer, refrigerator or freezer. The high
temperatures radiated by the hob
could damage the appliance below.

Warning and Safety Instructions

Safety distance above the appliance

Fig. 4

As a general rule there must be a

c

safety distance of at least 760 mm
between the appliance and any
flammable objects sited above, e.g.
wall units. If the manufacturer of the
said objects states a different figure,
either greater or smaller, then this
should be adhered to.

When two or more appliances are in­stalled together, the maximum dis­tance quoted between the cooker
hood and the appliance must al­ways be observed. These measure­ments are given in the operating
and installation instructions for the
cooker hood.

Space required for gas appliances

Minimum requirements are more than

3

20 m

space where the appliance is in­stalled, and a door or window which
can be opened to the outside air.

All dimesions 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.

Cut-out for the worktop

Fig. 6

Make a cut-out for the hob in the
worktop, paying attention to the ap­pliance depth. See Figures 5, 6,
and 7.
Dimension ‘B’ applies to a combina­tion of appliances and is shown on
the chart.

There must be a minimum distance
of 50 mm between the hob and the
back wall and 100 mm distance from
a side wall to the right or left of the
hob.

When building in several “combi”
hobs a spacer bar must be fitted be­tween each unit.
See the following page.

Seal the cut surfaces with a suitable
sealant to avoid swelling caused by
moisture.
The materials used must be heat re­sistant.

supplied. Gently adjust the hob if
necessary.

Fig. 10

On no account let sealant get in
between the hob frame and the
worktop.

This could lead to damage to the hob if
it needs to be taken out for servicing or
repair work. The seal provided under­neath the hob edge provides a suffi­cient seal between the appliance and
the worktop.

Other notes

Other notes

Electrical connection

Electrical work should be carried out by
a competent person, in strict accord­ance with national and local safety
regulations.
The voltage and rated load are given
on the data plate. Ensure that these
match the household mains supply.

After the appliance has been built in,
a check must be made that all electri­cal parts are shielded.

Connection for each 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
which is accessible after the appliance
has been built in.

When switched off there must be an all­pole gap of at least 3 mm in the isolator
switch. For extra safety it is advisable
to install a residual current device
(RCD) with a trip current of 30 mA.

Important

The wires in the mains lead are col­oured in accordance with the following
code:
Green/yellow = earth
Blue = neutral
Brown = live

Disconnection from the power supply
will depend on the isolator, according
to country e.g.:

1. Safety fuse:

Completely remove the fuse links
from the fuse carrier. or:

2. Safety cut-outs (screw type):

Press the (red) test button until
the black centre button pops out.

or:

3. Built-in safety cut-outs (MCBs at

least type B or C):

Set rocker from 1 (On) to O (OFF) or:

4. FI-Safety switch (RCD)
Set main switch from 1 (ON) to
O (Off) or press the test button.

Technical Data

Fusing: See data plate.

For appliances up to 3 kW - 13 amps
For appliances above 3 kW - 20 amps

If the cable needs to be changed se­lect either type H 05 RR-F (rubber insu­lated) or type H 05 VV-F (PVC-insu­lated).
See data plate for connection data.

Important

The manufacturer cannot be held re­sponsible for the consequences of an
inadequate earthing system.

WARNING THIS APPLIANCE MUST
BE EARTHED

Ensure power is not restored to the
appliance while installation work is
being carried out.

The manufacturer can assume no re­sponsibility for damage which is the di­rect or indirect result of incorrect instal­lation or connection.

11

Gas connection

Gas connection

Connection to the gas supply
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.

The hob is supplied ready for connec­tion to town gas.

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).

12

Technik

The gas connection must be in ac­cordance with national and local
regulations.

Fig. 11

Gas connection

Town gas / LP gas

An appropriate rigid or flexible con­nection can be used.

The gas connection must be so sited
that it is not adversely heated when
the appliance is in operation.

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.

town gas. Inlet pressure 10-20 mbar/
1-2 kPa, burner pressure 10 mbar/

A test for possible leakages should
be carried out after installation.

The relevant building regulations must
also be observed.

Note: Where a flexible connection (Hose Assembly) is used it must
(I) be of an adequate size and;
(II) comply with the National standard or AGA certification and;
(III) be suitable for the intended use.
