Safety precautions
• Toavoid any possible hazard, the appliance must be installed by Registered Gas Installer
employed by Registered Gas Contractors only.
• Duringthe operation of gas burners, the room may be filled with extra heat and humidity, so it
is necessary to assure adequate ventilation by keeping the natural air vents and by activating
the mechanicalaeration device (suction hood or ventilating fan).
• During the prolonged use of the appliance, or duringa very intense use, more ventilation will be
required. This can be achieved by opening a window or by increasing the power of the
mechanical exhausting system.
• Never use the burners if the flame of the outlet gas isunstable.
• In case you should smell gas in the room, immediately shut the main gas supply valve,
extinguish all open fires (including the cigarette), and abundantly ventilate the room. Avoid
using the telephone or operate any electrical switches and appliances; leave the premises at
once and notify your neighbours by knocking on their doors for immediate evacuaiton when the
gas leak is serious or when the situation is uncertain; leave the building by the stairs, dial 999
to notify the Fire Services Department, and call your gas supply company for sending their
emergency personnel to the scene to deal with the gas leak. Let your gas supply company
check all your gas installation for safety before you use gas again.
• The main gas supply valve must be shut also in case you do not intend to use the gas burners
for any considerable amount of time (i.e. leaving for a vacation).
• Particular cooktop areas (especially the hotplates) may become very hot during operation. Do
not let small children in the vicinityof the cooker and warnthem aboutthe danger of burns.
• Hot grease is highly inflammable, so pay extra attention when preparing food with grease or oil.
Frying in fat or oil (chips) may be carried out only under constant surveillance.
• Hotplates may not operate empty,without dishes placed ontop.
• Never use the appliance for heating of theroom.
• In case of any detected malfunction immediately suspend the appliance from the main gas and
electricity supply and call theservice.
• The appliance is manufactured in compliance with the relevant effective safety standards.
Nevertheless, we strongly recommend that persons with impaired physical, motoric, or mental
capacity, or persons with inadequate experienceor knowledge, donot use the appliance
unless attended by a qualified person. The same recommendation applies when the
appliance is used by persons of less-than-legal age.
• User should not leave the gas stove unattended while cooking.
Special warning for glass ceramic hob
The top panel of this cooker is made of ceramic glass which is safer than normal glass for this
application. However, the following safety precautions for using gas hob with glass top panel
should also be noted in order to prevent the glass top panel from breaking:
• Clean the burnerassembly frequentlyto maintain a clear gas passage on the flame distributor.
Clean and tidy up the flame distributor after spillage of food and liquid once the hob is turned
off and burner assembly cooleddown.
• Turnoff the gas appliance immediately if abnormalnoisepropagates from the gas appliance
andcontact gas supplycompany or gas hobimporter for inspection.
• Do not use oversized utensils for cooking. Please refer to Instructions for use in P.7.
• Do not impact the glass surface with sharpor hard objects or place heavy objects on the glass
surface.
• If you notice any cracks on the ceramic glass surface, stop using the hob immediately because
there is danger of electric shock! Switch all burners off and disconnect the hob from the mains
by unplugging the mains lead or switch off the fuse. Call service assistance.
• Sand particles or rough wrought iron pot bottoms may also produce scratches upon the glass
ceramic surface.

Instructions for use
WARNINGS AND ADVICE:
• Use of a gas cooking appliance produces heat and moisture
in the room in which it is installed. The room must
therefore be well ventilated by keeping the natural air vents
(see FIG. 3) and by activating the mechanical aeration
device(suction hood or ventilatingfan FIG. 4 and FIG. 5).
• Intensive and lengthy use of the appliance may require
additional ventilation. This can be achieved by opening
a window or by increasing the power of the mechanical
exhausting system.
• When built-in gas hob is installed on top of stove cabinet,
please check that there is provision for ventilation at the
cabinet and do not store any flammable materials,
sprays or pressurized containers inside the stove
cabinet.

Cleaning
•Periodically wash the hot plate, the enamelled steel pan
support, the burner crown caps “A” and “C”, outer
burner cap “B”, and the burner crown "T” (see FIG. 6
and 7) with lukewarm soapy water. Ignition plug "AC"
and safety device "TC" (see FIG.6) should also be
cleaned
•Clean the burner head gently with a small nylon brush
as shown (see FIG.7/A) and allow fully dry. Do not wash
the component in the dishwasher. It is very important to
clean the surface soon after every use.
•Do not allow vinegar, coffee, milk, salted water, lemon
or tomato juice from remaining in contact with the
enamelled surfaces for long period of time.
•Do not clean using abrasive metal scourers,
powder abrasives or corrosive sprays. Use a wet
sponge is sufficient.
WARNINGS AND ADVICE:
When reassembling the components, beware of following recommendations:
•Check and make sure that the gas passage in the burner crown “T” (FIG. 6) is not blocked by
foreign objects.
•Make sure the burner crown caps “A”, “B” and “C”, (FIG. 6and 7) are correctly positioned on the
burner crown. The caps are correctly positioned when they are perfectly stable. Any incorrect
positioning of the burner crown cap as shown in the lower part of Fig. 7 will result in the burnout
and deformation of burner crown cap and leading to blockage of gas passage on the burner
crown, resulting in the flame not being able to burn externally and returning partially to the bottom
of the glass panel. Abnormal build-up of heat at the bottom of the glass panel will eventually lead
to breaking of the glass panel.
•The pan support must be placed in the appropriate centering pins for perfect stability.
