Operation
Hob burners
To light a burner:
)
z push in the relevant control and turn it to maximum
position;
z then adjust the flame as required.
z If the burner does not ignite, turn the control knob to
zero, and try again.
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.
As soon as a liquid starts boiling, turn down the
flame so that it will barely keep the liquid
simmering.
Triple-crown Burner
If the control knobs become difficult to turn, please
contact your local Service Force Centre.

This hob must be installed by a competent
person to the relevant Gas Standards.
Once the hob has been installed, it is important
to remove any protective materials, which were
put on in the factory.
Any gas installation must be carried out by a
registered competent person.
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.
The manufacturer will not accept liability, should
the above instructions or any of the other safety
instructions incorporated in this book be
ignored.
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.
Failure to ensure the correct assembly will cause
leakage of gas.
