This appliance is class 3
The flame can be set to the desired position by turning
the control knob through the adjustment range in an anti-
clockwise direction.
Igniting the Burners
To ignite the burners, follow these instructions:
1. Lightly press the control knob (shown on the right) and turn the knob anti-
clockwise to the maximum position. Press and hold the control down to
begin the ignition process (a clicking sound will be heard).
2. Once the burner is lit, adjust the burner power to the required position.
To turn the burner off, turn the knob clockwise past the maximum setting to
the off position.
Some models are fitted with a flame-failure device (designated by ‘F’ in model
number). If your hob is fitted with such a device, hold down the control knob for
a few seconds after ignition to allow the safety device to detect that the burner is
lit. Flame-failure devices operate by shutting off the supply of gas to the burner in
the event that the flame is extinguished accidentally.
Fig.2
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.
Fig.3
The table below shows the sizes of pan that should be used with each burner:

Care and Maintenance
As the hob has a stainless steel or enamel surface, 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.
Over time with use, the stainless steel surface may discolour; this is normal and does not constitute a fault with this ap-
pliance. Proprietary stainless steel cleaners are available. We recommend the CDA E-Cloth available from the CDA Sales
Team for cleaning stainless steel surfaces.
The enamelled parts of hobs are not suitable for cleaning in dishwashers; these should be washed by hand.
IMPORTANT:
•
•
•
Steam cleaners must not be used when cleaning this appliance.
Ensure that all parts are correctly replaced after cleaning before attempting to use the hob.
After removing the pan stands, ensure the rubber pads are in place on the base of the pan stand before repositioning
the pan stands straight and level on the hob.
What to do if you smell gas:
1. Open doors and windows
2. Turn the gas supply off
3. Call Transco on : 0800 111 999

Fitting the Hob
Unpacking the hob:
Take care not to lose or mishandle any parts.
Fitting position of the hob:
This appliance must be installed a minimum of 50mm from any back wall and a minimum of 185mm away from any
adjacent vertical surfaces, e.g. a tall cupboard end panel. This may be reduced to 100mm 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 700mm (750mm
is recommended) (Fig.7). If the instructions supplied with the hood dictate that the hood must be installed at a height
greater than 700mm, 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 400mm, 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 capable of withstanding temperatures of 65°C or greater
above ambient temperature.
•
•
If there is no oven to be built in below the hob, 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 and user from the heat generated during use. This should be fitted 100mm below the hob.
Never place perishable foods in the cupboard below the appliance.
How to install the hob:
Overall dimensions of the hob: Width: 585mm Depth: 500mm
Worktop cut-out dimensions: Width: 550mm Depth: 470mm
1. Make the required hole in the worktop. Before doing this, you must check the instructions supplied with any cooker
hood to ensure that you will have the required clearance. The cut-out (Fig.4) shows a 65mm gap from the wall to the
cut-out edge. The distance from the hob, when fitted, to the back wall is 50mm.
If a splashback/worktop upstand is to be fitted, take this into account when cutting the hole. The minimum distance that the
hob should be positioned away from the rear wall or splashback is 50mm.
2. Position the hob seal, as shown in Fig.6, ensuring that the ends meet without overlapping. Do not use silicone type sealant.
3. Secure the hob to the worktop using the fixing brackets and screws supplied, as shown in Fig.7. Remove any excess
sealant after tightening the brackets. Do not over-tighten the fixing brackets.
