);
Maintenance
and Cleaning
Before any maintenance or cleaning
can be carried out, you must
DISCONNECT the hob from the
electricity supply .
The hob is best cleaned whilst it is still
warm, as spillage can be removed
more easily than if it is left to cool.
The Hob T op
Regularly wipe over the hob top using a soft
cloth well wrung out in warm water to which a
little washing up liquid has been added. Avoid
the use of the following:
- household detergent and bleaches;
- impregnated pads unsuitable for non-stick
saucepans;
- steel wool pads;
- bath/sink stain removers.
Should the hob top become heavily soiled, it is
recommended that a cleaning product such
as Hob Brite or Bar Keepers Friend is used.
As soon as a liquid starts boiling, turn
down the flame so that it will barely
keep the liquid simmering.
If the control knobs become difficult to
turn, please contact your local Service
Force Centre.
If you use a saucepan which is smaller
than the recommended size, the flame
will spread beyond the bottom of the
vessel, causing the handle to overheat.
Take care when frying food in hot
oil or fat, as the overheated
splashes could easily ignite.
Pan Supports
The pan supports are dishwasher proof. If
washing them by hand, take care when drying
them as the enamelling process occasionally
leaves rough edges. If necessay, remove
stubborn stains using a paste cleaner.
Ignition candle
The electric ignition is obtained through a
ceramic "candle" and a metal electrode (fig. 1,
letter C). Keep these components well clean,
to avoid difficult lighting, and check that the
burner crown holes are not obstructed.
The Burners
The burner caps and crowns can be removed
for cleaning. Wash the burner caps and crowns
using hot soapy water, and remove marks with
a mild paste cleaner. A well moistened soap
impregnated steel wool pad can be used with
caution, if the marks are particularly difficult to
remove. After cleaning, be sure to wipe dry
with a soft cloth.

m3 and 10 m3 an air vent of effective area of
50 cm2 is required, while if the volume exceeds
11 m3 no air vent is required.
However, if the room has a door which opens
directly to the outside no air vent is required
even if the volume is between 5 m3 and 11 m3.
If there are other fuel burning appliances in
the same room, B.S. 5440 Part 2 Current
Edition, should be consulted to determine the
requisite air vent requirements.
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

Installation
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
components as shown in the diagram. Screw
the parts together without using excessive
force.
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).
When the final connection has been made, it
is essential that a thorough leak test is carried
out on the hob and installation.
Ensure that the main connection pipe does
not exert any strain on the hob.
It is important to install the elbow
correctly , with the shoulder on the end
of the thread, fitted to the hob
connecting pipe.
