turn it anti-clockwise to the maximum position.
oIf you keep the control knob depressed, 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.
Energy saving tips

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

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 stainless steel
cleaner and polish is regularly used on the stainless steel
surfaces of this appliance.
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.
12

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.

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.
