Before first use
• Before using the oven for the first time we recommend that you
clean the oven with soapy water, rinse carefully dry thoroughly,
and then heat at maximum temperature on the grill function
for 15 minutes and the oven function for one hour. A slightly
unpleasant smell may be produced, caused by grease remaining
on the oven from the production process.
• Your hob may take a little longer than normal to ignite each burner
upon first use. This is normal and is not indicative of a fault. Before
igniting your burner(s) for the first time, please carry out the checks
on page 7.
Please note:
• This oven has been fitted with a cooling fan to achieve maximum
efficiency and to maintain low surface temperatures. The cooling
fan will switch on automatically when the oven reaches a preset
temperature and switch off automatically when the oven has
cooled sufficiently, even after the oven is switched off (but
not when the appliance has been disconnected from the mains
supply).
• The oven is equipped with a safety thermostat which will switch
off the oven to prevent overheating. Overheating can be caused
by incorrect use of the oven or defective components. If the
oven switches off due to overheating, wait for the oven to cool
down before using it again. If the error continues, contact CDA
Customer Care.

7
Before using the hob
• Before lighting the hob burners, check
that the flame-spreaders (F) are in
position with their respective burner
caps (C), ensuring that the holes in the
flame-spreaders are aligned with
the ignition electrodes (S) and
thermocouples (T) as shown in fig. 1.
• Once the contents come to the
boil, turn down the flame far enough to
prevent the liquid from boiling over. To
prevent burns or damage to the
hob during cooking, all pans or
griddle plates must be placed inside the perimeter of the hob.
• Place the pan on the pan supports with the handles facing away
from the edge of the work top. This will reduce the risk of the pan
being knocked or pulled over.
Deep Fat Frying
• Only fill the pan one third full of oil.
• Do not put a lid on the pan and never leave the pan unattended.
• In the event of a fire, do not move the pan and turn off all
control knobs.
• Then put a damp cloth over the pan, or a correctly fitting lid to
smother the flames.
• Do not put water on the fire.
• Leave the pan to cool for at least 30 minutes before attempting to
move it.

Gas burners:
Gas flow to the burners is controlled by the control knobs (6 - 10 on the
diagram on the previous page). There are 3 positions shown on the
control panel. Turning the control knob to the positions shown below
achieves the following:
Closed (OFF position)
Maximum position: Provides fast boiling function
Minimum position: Provides simmer function
The hob can be set to the desired position by turning the control
knob through the adjustment range in an anti-clockwise direction.

10
Igniting the burners
The hob is fitted with a flame failure device. Flame failure devices
operate by shutting off the supply of gas to the burner in the event
that the flame is extinguished accidentally.
To ignite the burners, follow these
instructions:
1. Lightly press the control knob down
and turn the knob anticlockwise to
the maximum position. Firmly press and
hold down the control knob to begin the ignition process (a clicking
sound will be heard). Hold down the control knob for a few
seconds after ignition to allow the safety device to detect that the
burner is lit.
2. Once the burner is lit, adjust the burner power to the required
position.
Please note:
• The ignition device should not be operated for more than
15 seconds.
• If a burner does not ignite, or turns off accidentally, turn the
control knob to the ‘off’ position, and wait for one minute before
attempting to reignite the burner.
• If the burner does not ignite, repeat the ignition process with the
burner at the minimum position.

Efficient use of your Hob
The hob is equipped with burners of different sizes, designed to
accommodate most shapes and sizes of pan. For best results,
only use pans with flat bottoms and choose an appropriate burner
depending on the size of the pan. The most efficient use of the hob is
shown below, where the pan and burner are correctly chosen.
Ensure that the pans do not overlap the edge of the pan stand, or
cover the control panel. Position the pan centrally above the burner.
The table below shows the sizes of pan that should be used with
each burner:

Correct use of the wok
pan adaptor
The wok pan adaptor is a special
stand that is designed to be fitted over
the triple ring burner to give support to
round bottomed woks.
When using a wok, always place the
wok pan adaptor in position over the
pan support on the triple ring burner as
shown in Fig.6.
IMPORTANT:
• The wok pan adaptor (Fig.6) must be
placed over the pan support on the
triple ring burner.
• Do not use the wok pan adaptor for
standard flat bottomed pans.

Care and Maintenance
Cleaning the Cooker
IMPORTANT:
Always disconnect the appliance from the power supply before
undertaking any cleaning or maintenance.
You should always allow the cooker to cool fully after use before
undertaking any cleaning or maintenance.
• Steam cleaners must not be used when cleaning this appliance
• Clean the cooker regularly and remove spills as soon as they
occur.
• Do not allow fat or oils to build up on the hob or in the oven.
• Do not place hot enamel parts (e.g. burner caps, grill pan) in water.
Leave them to cool first.
• Do not allow vinegar, coffee, milk, saltwater, lemon or tomato juice
to remain in contact with enamel parts
• Do not use abrasive or corrosive cleaners (including scouring pads
or Cif) as these could scratch the appliance, remove control panel
markings or damage the cooker.
• Do not clean the removable parts of the cooker in a dishwasher,
these must be washed by hand.
For the glass and stainless steel surfaces, you should use a
nonabrasive cleaner. Any abrasive cleaner (including Cif) will scratch
the surface and could erase the control panel markings. Stainless
steel can be effectively cleaned by simply using a dilute solution of
water and mild detergent and drying to a shine with a clean cloth.

17
Over time with use, the stainless steel surface may discolour;
this is normal and does not constitute a fault with this appliance.
Proprietary stainless steel cleaners are available.
Cleaning the oven interior
To clean the oven interior, suitable proprietary
chemical cleaners may be used after
first consulting with the manufacturer’s
recommendations and testing a small sample
on the oven cavity.
Do not use metal scrapers or harsh cleaners on the oven door
glass. These could cause scratches, which may result in the glass
shattering.
To remove the side racks, press down on the
top bar of the side rack to free the rack from the
top securing pin, then remove the side rack by
lowering it out so that the hooks on the lower edge are freed from the
oven cavity (as shown in fig. 9 and 10).
To replace the side racks, locate the lower
hooks in the oven cavity, then pivot the side rack
back into position, pressing the top bar down to
relocate it against the securing pin.
Ensure that all parts are correctly replaced after cleaning before
attempting to use the cooker, and that the rubber pads are in place
on the base of the pan stands before repositioning the pan stands
on the hob top. To replace the hob burner parts correctly, refer to fig.
1 on page 7.
