Switching the hob on
The following symbols will appear on the control panel, next to each
control knob:
= gas off
Large flame: maximum setting
Small flame: minimum setting
oThe minimum setting is at the end of the anti-clockwise rotation
of the control knob.
oAll operation positions must be selected between the maximum
and minimum position.
oNever select a knob position between the maximum and off
position.
oThe symbol on the control panel, next to the control knob will
indicate which gas burner it operates.
11

Automatic ignition with flame failure safety device
The appliance is fitted with a flame failure safety device on each
burner, which is designed to stop the flow of gas to the burner head in
the event of the flame going out.
To ignite a burner:
oPress in the control knob of the burner that you wish to light and
turn it anti-clockwise to the maximum position.
oIf you keep the control knob pressed, the automatic ignition for
the burner will operate.
oYou should hold down the control knob for 20 seconds after the
flame on the burner has lit.
oAfter this 20 second interval, turn the control knob to your
required setting between the maximum and minimum setting
symbols.
oTo switch the burner off, turn the control knob fully clockwise to
the gas off position.
oIn case of power failure, the burners can be lit by carefully using
a match.

oThe burner flame must never extend beyond the diametre of the
pan.
oUse flat bottomed pans only
oWhen possible, keep a lid on the pan whilst cooking.
oCook vegetables with as little water as possible, to reduce
cooking times.
IMPORTANT: Always place pans centrally over the hob burners and
position them so that the handles cannot get accidentally caught or
knocked off. You should also make sure that the handle is not over one
of the other hob burner flames.
Cleaning
Cleaning operations must only be carried out when
the hob is cool.
The appliance should be disconnected from your
mains supply before commencing any cleaning
process.
Cleaning the hob top
Any residues that are left on the hob top surface from cleaning
agents will damage it. You should remove any residues with
warm soapy water.
Abrasive cleaners or sharp objects will damage the hob surface;
you should clean it using warm soapy water.
Although it is easier to clean some deposits whilst the
hob surface is still warm. Make sure that the hob surface,
pan supports and hob burners have all cooled sufficiently
before you attempt to touch them.
After each use
oRemove the pan stands and wipe the appliance over with a soft,
damp cloth that has been put into warm soapy water. The cloth
should be wrung out after being taken out of the soapy water.
oDry the appliance by rubbing the surface with a soft, clean cloth.

oWe would recommend that an appropriate neutral and non-
flammable detergent is used to clean the glass surface of the
hob.
Cleaning the hob burners
The hob burners should be cleaned once a week or more frequently if
they get soiled.
oIMPORTANT: Make sure that the hob surface, pan stands and
hob burners have cooled before you attempt to touch them.
oRemove the hob burners by pulling them upwards and away
from the hob top.
oSoak them for about ten minutes in hot water and a little
detergent.
oAfter cleaning and washing them, wipe and dry them carefully.
oBefore placing the burners back on the hob top, make sure that
the gas jet is not blocked.
oIMPORTANT: Make sure that you reassemble the burners in the
original way.
Maintaining the cast iron pan stands
oIMPORTANT: Make sure that the hob surface and pan stands
have cooled before you attempt to touch them.
oWipe the pan stands over with a soft, damp cloth that has been
put into warm soapy water. The cloth should be wrung out after
being taken out of the soapy water.
oUsing a paper towel, thoroughly dry the pan stands.
oTo maintain the appearance of the cast iron pan stands, we
would recommend that you rub a small amount of olive oil into
the pan stands, after you have finished cleaning them.
