SAFETY INSTRUCTIONS
Please pay attention to children whilst the cooker is in operation, as children do not know
the rules of cooker use. In particular, hot surface burners, the oven chamber, grates,
the door pane, and pans containing hot liquids standing on the hob may cause burns to
children.
Mind that electrical connection leads from other home appliances (e.g. of a food mixer)
do not touch hot parts of the cooker.
 Do not place ammable material into the drawer whilst using the oven, as it may catch a
re.
 Do not leave the cooker unattended when frying. Oils and fats may catch re due to
overheating.
At the point of boiling, mind to avoid spills on the burner.
 If the cooker is damaged, it may be used again only after the fault has been xed by a
specialist.
Do not open the tap on the gas connection or cylinder valve before checking that all burner
knobs are closed.
Do not allow the burners to be soiled or liquids to spill on the burners. If soiled, clean and
dry burners immediately after they have cooled down.
Do not put pans directly onto burners.
Do not place pans with a weight greater than 10 kg onto the grate over one burner, or
pans with a total weight of over 40 kg on the whole grate.
Do not hit the knobs and burners.
Do not put objects with a weight greater than 15 kg onto the open oven door.
 Alterations and repairs carried out by an unqualied person are not allowed.
Do not open the cooker knobs before already having a lighted match or a gas lighter in
your hand.
 Do not put out a burner ame by blowing.
 A glass cover may crack when heated. Switch o󰀨 all the burners before lowering the cover.
(Cookers with a glass cover).

SAFETY INSTRUCTIONS
 Do not make your own alterations to the cooker in order to adapt it to a di󰀨erent type
of gas, move the cooker to another place or make changes to the power supply. These
operations may only be carried out by an authorised electrician or tter.
Do not use harsh cleaning agents or sharp metal objects to clean the door as they can
scratch the surface, which could then result in the glass cracking.
Keep young children and people not acquainted with the instruction manual away from
the cooker.
 IN CASE OF ANY SUSPICION OF GAS LEAKAGE YOU MUST NOT:
light matches, smoke cigarettes, switch electrical receivers (door bell or light switch) on
and o󰀨, or use other electric and mechanical devices that create electrical or percussive
sparks. In such a case, immediately close the cylinder valve or tap cutting o󰀨 gas supply,
air the room, and then call a person authorised to repair the source of the leakage.
In the event of any incident caused by a technical fault, disconnect the power (applying
the above rule) and report the fault to the service centre to be repaired.
Do not attach any antenna cords (e.g. radio) to the gas supply.
 In a case of gas escaping from leaky piping and catching re, close gas supply immediately
using a cutting-o󰀨 valve.
 In a case of gas escaping from a leaky cylinder and catching re: throw a wet blanket over
the cylinder to cool it down and turn o󰀨 the cylinder valve. After it has cooled down, take
the cylinder out to an open space. Do not use the damaged cylinder.
When the cooker is not to be used for several days, close the main valve on the gas pip-
ing; when using a gas cylinder, close it after each use.
Using the appliance for cooking and baking results in the emission of heat and moisture in
the room in which it is installed. Make sure that kitchen is well ventilated. Natural ventila-
tion openings or forced mechanical ventilation (exhaust hood) should be available.
Prolonged intensive use of the appliance may require additional ventilation, for example,
opening a window or a more e󰀨ective ventilation, such as increasing e󰀩ciency of mechani-
cal ventilation, if applicable.
The appliance has been designed only for cooking. Any other use (for example for heat-
ing) does not comply with its operating prole and may cause danger.

HOW TO SAVE ENERGY
Using energy in a respon-
sible way not only saves
money but also helps the
environment. So let’s save
energy! And this is how you
can do it:
Use proper pans for cooking.
A saucepan should never be smaller than a
burner crown.
Always remember to cover and pans.
Ensure burners, the grate the hob are
clean.
Soils can prevent heat transfer – and repeat-
edly burnt-on spillages can often only be
removed by products which cause damage
to the environment.
In particular, ensure that ame openings in
the rings under caps, and openings of burner
nozzles are clean.
Do not uncover the pan too often (a
watched pot never boils!).
Do not open the oven door unnecessarily
often.
Only use the oven when cooking larger
dishes.
Meat of up to 1 kg can be prepared more
economically in a pan on the cooker burner.
Make use of residual heat from the
oven.
If the cooking time is greater than 40 minutes
it is recommended to switch o󰀨 the oven 10
minutes before the end time.
Make sure the oven door is properly
closed.
Heat can leak through spillages on the door
seals. Clean up any spillages immediately.
Do not install the cooker in the direct
vicinity of refrigerators/freezers.
Otherwise energy consumption increases
unnecessarily.

INSTALLATION
The following instructions are addressed to
the qualied specialist installing the cooker.
These instructions aim at ensuring that
installation and maintenance activities are
performed as professionally as possible.
Installing the cooker
The kitchen should be dry and airy and
have e󰀨ective ventilation according to the
existing technical provisions.
The room should be equipped with a ven-
tilation system that pipes away exhaust
fumes created during combustion. This
system should consist of a ventilation
grid or hood. Hoods should be installed
according to the manufacturer’s instruc-
tions. The cooker should be placed so
as to ensure free access to all control
elements.
The room should also enable the neces-
sary air supply for proper gas combustion.
Air supply should be not less than 2m3/h
per 1 kW of burner heat. The air can be
delivered from outside by a duct with a
section of at least 100cm2, or indirectly
from adjoining rooms which are tted with
ventilation ducts leading outside.
If the appliance is used intensively and for
a long time, it may be necessary to open
a window in order to improve ventilation.
In terms of protection against the over-
heating of surrounding surfaces, the gas
cooker is an X – class appliance and
can be built into furniture only up to the
level of the cooking hob, that is around
850 mm above the oor. Raising furniture
construction over this level is inadvisable.
Coating or veneer used on tted furniture
must be applied with a heat resistant
adhesive (100°C). This prevents surface
deformation or detachment of the coat-
ing. If you are unsure of your furniture’s
heat resistance, you should leave ap-
proximately 2 cm of free space around
the cooker. The wall behind the cooker
should be resistant to high temperatures.
During operation, its back side can warm
up to around 50°C above the ambient
temperature.

The cooker should stand on a hard, even
oor (do not put it on a base).
Before you start using the cooker it should
be leveled, which is particularly important
for fat distribution in a frying pan. To this
purpose, adjustable feet are accessible
after removal of the drawer. The adjust-
ment range is +/- 5 mm.

Gas connection
Caution!
The cooker should be connected to a
gas supply of the particular type of gas
that the appliance is manufactured to
function with. Information about the
type of gas that the cooker has been
adapted to by the factory is shown on
the data plate. The cooker should be
connected exclusively by an appropri-
ately authorised tter and only he or
she has the right to adapt the cooker
to a di󰀨erent type of gas.
INSTALLATION
Fitting guidelines
A tter should:
 have a gas tter’s authorisation,
be acquainted with the information in-
cluded on the data plate of the cooker
about the type of gas to which the cooker
is adapted; the information should be
compared with gas supply conditions at
the place of installation,
 check:
- airing e󰀩ciency, that is e󰀩ciency of air
exchange in the rooms,
- tightness of gas tting connections,
- e󰀨ectiveness of all functional elements of
the cooker,
- if the electricity supply is adapted to func-
tion with a safety ground lead (zero).
provide the user with a connection cer-
ticate and give him or her instructions
in cooker use.
Caution!
The cooker may only be connected
to a liquid gas cylinder or the existing
gas supply by an authorised tter,
observing all safety rules.

If the cooker is connected according to the
class 2 specications, sub-class I, only ex-
ible metal hose can be used which meet the
valid national regulations. Gas feeding con-
nector must be G ½” threaded coupling.
Use only pipes and ttings that meet the
requirements of the valid standards. Maxi-
mum admissible length of the exible hose
is 2000 mm.
Make sure the connection is not touching
any mobile elements which could damage
the hose.
Connection with a stable pipework.
The cooker comes with a G ½” threaded
coupling.
The connection to gas supply must be done in
a manner that excludes stresses in any point
of the pipework or parts of the appliance.
Make sure you do not exceed the torque
when making the connection (maximum
torque is 20 Nm). Otherwise, the connection
may be faulty or leaks may occur.
The gas hose should not touch metal ele-
ments of the cooker back shield.
The cooker is manufactured to work with
a one-phase alternating current (230V
1N~+ PE 50 Hz) and is equipped with a
3 x 1,5 mm2connection lead of 1.5 mm
length with a plug including a protection
contact.
A connection socket for electricity supply
should be equipped with a protection
pin and may not be located above the
cooker. After the cooker is positioned, it is
necessary to make the connection socket
accessible to the user.
Before connecting the cooker to the
socket, check if:
- the fuse and electricity supply are able to
withstand the cooker load,
- the electricity supply is equipped with an
e󰀩cacious ground system which meets
the requirements of current standards
and provisions,
- the plug is within easy reach.
Electrical connection
Caution!
The cooker may only be connected
to a liquid gas cylinder or the existing
gas supply by an authorised tter,
observing all safety rules.
Caution!
On completion of the cooker installa-
tion, the tightness of all connections
should be checked, e.g. applying
water with soap.
Do not use re to check tightness.
Important!
Each time you replace a reducer
carry out technical inspection of the
cooker that covers gas valves and
proper operation of the ame failure
cut-o󰀨 device.

Adapting the cooker to another
type of gas.
This operation may only be carried out by an
appropriately authorised tter.
If the gas the cooker is to be supplied with
di󰀨ers from the gas provided for the cooker
by the manufacturer, that is G20 20 mbar,
burner nozzles must be exchanged and the
ame needs to be adjusted.

16
Surface burners applied do not require adjust-
ment of primary air. A correct ame has dis-
tinct internal cones of blue and green colour.
A short, humming ame or long, yellow and
smoking one, without clearly outlined cones,
shows improper quality of gas in the house-
hold piping or a damaged or soiled burner.
In order to check a ame, heat a burner for
around 10 minutes with a full ame, and next
turn the valve knob to the economical ame
position. The ame should not go out or jump
onto the nozzles.
INSTALLATION
Caution!
Adapting the appliance to a di󰀨erent
type of gas than that indicated by the
manufacturer of the cooker on the
data plate, or purchasing a cooker for
a di󰀨erent type of gas than supplied to
the house, is exclusively the responsi-
bility of the user and the tter.
Exchange of a burner noz-
zle – unscrew the nozzle
with special socket span-
ner No 7 and replace with
a new one according to a
type of gas (see tables).
In cookers with a safety device, a knob with
a surface burner safety valve is used, g.
Knobs should be adjusted with the burner
switched on and set to the economical ame
position, using an adjustment screwdriver of
the 2.5 mm size.

OPERATION
How to use surface burners
Choice of cookware
Mind that the diameter of a pan base is always
larger than the burner ame crown, and that
the pan itself is covered. The recommended
pan diameter is around 2.5 to 3 times larger
than the burner diameter, that is, for:
an auxiliary burner – a pan with a diameter
of 90 to 150 mm,
a medium burner – a pan with a diameter
of 160 to 220 mm,
a large burner – a pan with a diameter of
200 to 240 mm, and the pan height should
not be greater than its diameter.
Ignition without an ignitor
light a match,
press in the knob to the end and turn it
left to the “large ame” position
ignite gas with a match,
set required ame size (e.g. “economical”
),
switch o󰀨 the burner after nishing cook-
ing, turning the knob right (to the off
position).
Gas burner control knobs
Knob ignition
press in the knob to the end and turn it left
to the “large ame” position ,
hold until gas is lit,
after the ame is lighted release the pres-
sure on the knob and set a required ame
size.

OPERATION
Selection of the appropriate ame
A correctly adjusted burner has a light blue
ame with a clearly visible internal cone. Se-
lection of ame size depends on the position
of the burner knob which has been set:
large ame
small ame (“economical ame”)
 burner switched o󰀨 (gas supply is cut o󰀨)
Depending on requirements, ame size can
be set in a continuous manner.
Caution!
In cooker models equipped with a
surface burner safety valve, hold the
knob pressed down to the end when
igniting for 10 seconds at the “large
ame” position to activate the safety
device.
Caution!
Do not adjust the ame between the
o󰀨 position  and the large ame
position
Operation of the burner protection valve
Some models are equipped with an automatic
system that cuts o󰀨 gas supply to a burner
when the ame has disappeared.
This system protects the cooker against gas
leakage when the ame on a burner goes out
e.g. in case of spillage.
The user’s intervention is needed to re-ignite
the burner.
