Important Notes
Please note:
• Gas hobs become hot and remain hot during and immediately after
use. We strongly advise that you do not touch the hob, nor any of
its components, until it has been allowed to cool. If wiping away a
spillage, please take every care not to burn yourself.
• Keep children away from the appliance when in use.
• After use, ensure the control knobs are in the o position.
• Never use the hob top for storage.
• Pan handles should never stand out beyond the edge of the
worktop. This will help to ensure children cannot reach them.
• Ensure that the appliance is correctly adjusted for the type of gas
available before installation.
• The use of a gas appliance produces heat and humidity in the
room in which it is installed. Ensure that the room is well ventilated,
either by the use of natural ventilation outlets (e.g. windows) or an
externally ducted extractor.
• Do not lean over the hob when it is in use.
• Follow the cleaning instructions carefully.
• Ensure the base of any saucepan is clean and dry before placing it
on the hob.
• This hob (Class 3) has been designed for use only as a cooking
appliance. Any other use (e.g. heating rooms) should be
considered incorrect and therefore dangerous.
• The appliance is not intended to be operated by any means of an
external timer or separate remote-control system.
This appliance is class GB II2H3+

Gas burners
Gas flow to the burners is controlled by the control knobs (6, 7, 8, 9
and 10 in Fig. 1). There are 3 positions shown on the control panel
(Fig. 2). Turning the control knob to the positions shown below
achieves the following:
Closed (switches gas valve and burner o)
Maximum position (highest heat level) & ignition
position
Minimum position (lowest heat level)
The knobs should always be turned in an anticlockwise (left) direction
from the closed/o position. Attempting to ignite the burner in a
clockwise direction from the closed position may cause damage to
the hob.
Igniting the gas burners
This hob’s burners are fitted with flame failure devices. These
operate by shutting o the gas supply to the burner in the event
that the flame is extinguished whilst the control knob is in an open
position.
To ignite the burners
Press the control knob down and turn the knob anticlockwise (left)
to the maximum position. Hold the control knob down to begin the
ignition process (a constant clicking should be heard). Once the
flame appears around the burner, keep the control knob pressed

8
down for a few seconds (can be as long as 10 seconds) to allow the
flame failure device to detect the presence of the flame.
Once lit, release the control knob and turn it to the desired position
i.e. until the burner flame is at the required intensity.
Once you have finished cooking with the burner(s) in use, return the
control knobs to the closed (o) position.
Please note:
The ignition should not be operated (clicking constantly) for more
than 15 seconds at a time.
If a burner does not ignite, or turns o accidentally, turn the control
knobtotheclosed(o)position.Waitforoneminutebeforeattempting
to reignite the burner. The flame failure device will activate within
approximately 60 seconds.
If the burner does not ignite, repeat the ignition process with the
control knob at the minimum position.
If a burner continues to not ignite, please follow the troubleshooting
section on page 11. If the burner has been in use recently, allow it to
cool suciently before handling it.

Ecient use of your hob
The hob is equipped with burners of dierent sizes, designed to
accommodate most 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 ecient use of the hob is shown
below, where the pan and burner are correctly chosen.
•Use pan lids where possible to minimize the energy usage of
your appliance.
•Ensure that the pans do not overlap the edges of the pan
stands, nor cover the control panel.
The table below shows the sizes of pan that should be used with
each burner:

Care and maintenance
The hob has a stainless steel surface. Due to this you should use a
non-abrasive cleaner. Any abrasive cleaner (including Cif) will scratch
the surface and could erase the control panel markings. Stainless
steel can be eectively cleaned by simply using a dilute solution of
water and washing up liquid, and drying to a shine with a clean cloth.
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.
The cast iron parts of hobs (pan stands and burner caps on this
model) are not suitable for cleaning in dishwashers. They should be
washed by hand and dried thoroughly afterwards with a
clean, dry cloth.
IMPORTANT:
•Steam cleaners must not be used when cleaning this appliance.
•Ensure that all parts are correctly replaced after cleaning and
before attempting to use the hob.
• After removing the pan stands, ensure the rubber feet on the
undersides are in place and not contaminated with dirt/grit before
replacing the pan stands.
• If water enters the ignition candle area, this can cause them to
click constantly. This is not necessarily a fault. Switch the mains
power supply o and wait for the water to dry up.

11
Troubleshooting
IF YOUR HOB IS NOT WORKING:
1. Check that the mains supply has not been switched o.
2. Check that the fuse or circuit breaker has not blown/tripped.
3. Check that the burner crowns and caps are fitted correctly
and are not impeding the ignition candles or the flame failure
devices (circled in Fig. 4).
4. Check that the burner caps
(black metal plates that sit
atop the burners) are clean
and free from grease and
debris on both sides.
5. Check that the burners and
the burner caps are clean
and not soiled. Dirt, food
debris and other particles
can clog the burners, causing issues.
6. Check that the gas supply is on.
IMPORTANT: Ensure burners have been allowed to cool before
handling them.
If one or more burners continue to malfunction, please contact
CDA Customer Care. Contact details can be found below.

WHAT TO DO IF YOU SMELL GAS:
1. Turn o the gas.
For natural gas -
Turn o the gas supply at the meter situated at the emergency
control valve (ECV) unless the meter is located in a basement or
cellar. If there is a smell of gas in the basement or cellar, evacuate
the building.
For Liquefied Petroleum Gas (LPG) -
• Bulk storage supply - shut o the ECV outside the building
and the gas isolation valve on top of the above-ground storage
vessel(s), or underground storage vessel(s).
• Metered installations - shut o the ECV at the meter
installation outside the building.
• Cylinder fed installations - shut all cylinder valves.
2. Extinguish all naked flames.
Do not smoke, ignite a lighter of any kind or strike matches.
3. Do not operate electrical switches
Turning a light on or o, or activating any kind of switch or socket
outlet, can ignite escaping gas.
4. Open windows and doors
This gets rid of gas by ventilating the property. For LPG, ventilate at
low level (LPG is heavier than air).
Please note: If gas is evident externally, consideration should be
given to preventing gas entering the property (close windows and
doors etc.).

Fitting the hob
Fitting position of the hob:
This appliance, when installed, must be a minimum of 50mm
from any back wall and a minimum of 300mm away from any
adjacent vertical surfaces, e.g. a tall cupboard end panel. This may
be reduced to 150mm if the adjacent surface is resistant to fire
(tiles or steel, for example). These dimensions are shown in Fig. 6.
If fitting a cooker hood above the hob:
If a cooker hood is to be installed above the hob, the height of
the hood above the hob must be at least 750mm (Fig. 7). If the
instructions supplied with the hood dictate that the hood must be
installed at a height greater than 750mm, then that height is the
minimum required.
Wall furniture requirements:
The minimum height of any cabinet immediately above the hob is
900mm. The minimum height of any adjacent units (including light
pelmets) is 420mm, unless they are manufactured from a material
resistant to fire (steel, for example).
Notes:
•Do not position this appliance above a refrigeration unit. The
heat generated may cause the refrigeration unit to fail.
•This appliance is designed to be installed into cabinet units and
worktops capable of withstanding temperatures of 100°C +.
•If there is no oven to be built in below the hob it is recommended
that an isolation shelf should be fitted to protect the user from
high temperatures. If the hob is to be installed above a working
drawer, then a partition should be fitted to protect the contents
