Location
The hob may be located in a kitchen, a
kitchen/diner or bed sitting room, but not in
a bathroom, shower room or garage.Before
making the cut out in the worktop ensure
that the edges of the hob that are to be near
either a side or rear wall have a minimum
distance of 55 mm. between the edge of the
hob and the wall.
The minimum distance combustible
material can be fitted above the hob is 400
mm. If it is fitted below 400 mm. a space of
50 mm. must be allowed from the edges of
the hob.
The minimum distance combustible material
canbe fitteddirectlyabovethehob is700mm.
A minimum distance of 100 mm. must be
left between the side edges of the hob and
any adjacent cabinets or walls.

When the hob is first installed
Once the hob has been installed, it is
important to remove any protective
materials, which were put on in the
factory.
On the end of the shaft, which includes the
GJ 1/2" threaded elbow, adjustment is fixed
so that the washer is fitted between the
componentsasshowninthediagram.Screw

Gas Connection
Connection to the gas supply should be with
either rigid or semi-rigid pipe, i.e. steel or
copper.
The connection should be suitable for
connecting to RC 1/2 (1/2 BSP male thread).

Building In
Building over a cupboard or
drawer
If the hob is to be installed above a cupboard
or drawer it will be necessary to fit a heat
resistant board below the base of the hob on
the underside of the work surface.
It is also recommended to carry out the
electrical connection to the hob as shown in
diagrams 1 and 2.
Building over a kitchen unit
with door
Proper arrangements must be taken in
designingthefurnitureunit,inordertoavoidany
contact with the bottom of the hob which can
be heated when it is operated. The
recommendedsolution isshownindiagram3.
The panel fitted under the hob ("a") should
be easily removable to allow easy access if
technical assistance is needed. The space
behind the kitchen unit ("b") can be used for
connections.

The manufacturer declines any liability
should these safety measures not be
observed.
This hob is designed to be connected to a
230 V
~ 50 Hz AC electrical supply.
Before switching on, make sure the
electricity supply voltage is the same as that
indicated on the hob rating plate. The rating
plate is located on the bottom of the hob. A
copy is attached on the back cover of this
book.
The hob is supplied with a 3 core flexible
supply cable.
The wires in the mains lead are coloured in
accordancewith the following code:
GreenandYellow - Earth

Conversion from Natural Gas to LPG
It is important to note that this model is
designed for use with natural gas but can be
convertedforusewithbutane or propanegas
providing the correct injectors are fitted. The
gasrate is adjusted to suit.
Method
1. Ensure that the gas taps are in the 'OFF'
position
2. Isolatethehobfromtheelectricalsupply
3. Remove all pan supports, burner caps,
rings, crowns and control knobs.
4. With the aid of a 7mm box spanner the
burner injectors can then be unscrewed
and replaced by the appropriate LPG
injectors (see "Characteristics of gas
burners" on the next page).
To adjust the gas rate
With the aid of a thin bladed screwdriver
completely tighten down the by pass
adjustment screw. Upon completion affix the
replacementrating plate on theunderside of
the hob.
IMPORTANT
Thereplacement/conversionofthegas
hob should only be undertaken by a
competentperson.

Pressure Testing
Remove the pan supports and
the burner caps and crowns.
The pressure testing must be
carried out on the burners.
Proceed as follows:
1. Fit manometer tube over the
injector.
2. Turn on the burner gas supply
and ignite another burner.
3. The pressure reading should be
nominally 20 mbar and must be
between 17 mbar and 25 mbar.
4. Turn off the burner supplies.
