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

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).

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
