appliance has been allowed to cool.

• Keep children away from the appliance when in use.

• After use, please ensure that the gas taps are in the ‘O” position.

• 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 a ducted
extractor.

Igniting the Burners

The hob is fitted with a flame failure device. Flame failure devices
operate by shutting o 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.

The hob is fitted with a flame failure 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 o the supply of gas to the burner in the event that the
flame is extinguished accidentally.

Please note:

• The ignition device should not be operated for more than 15

seconds.

• If a burner does not ignite, or turns o accidentally, turn the control

knob to the ‘o’ 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.

Ecient use of your Hob

The hob is equipped with burners
of dierent 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 ecient 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.

The table below shows the sizes of pan
that should be used with each burner:

Care and Maintenence

As the hob has a glass surface, you should use a nonabrasive cleaner.
Any abrasive cleaner (including Cif) will scratch the surface and could
erase the control panel markings. Glass can be eectively cleaned by
simply using a dilute solution of water and mild detergent and drying
to a shine with a clean cloth.

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 o

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 150mm 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.5.

If tting 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.6).

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).

Ventilation slot > 30mm

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 65°C above ambient or greater
(typically 80-90°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 and user
from the heat generated during use.

This should be fitted at least 15mm below the hob. This panel should

have a ventilation space at the rear of greater than 30mm as shown
in fig. 5.

• Never place perishable foods in the cupboard below the appliance.

How to Install the Hob

How to install the hob:

Overall hob dimensions: HVG620 = 580mm (W) x 500mm (D)
HVG720 = 700mm (W) x 510mm (D)
Worktop cut-out dimensions: 557mm (W) x 477mm (D)

1. Make the required hole in the worktop. Note that before doing this,
check the instructions supplied with any cooker hood to ensure that
you will have the required clearance. The cut-out (Fig 6) shows a

61.5mm gap from the wall to the cut-out edge. The distance for the
hob, when fitted, to the back wall is 50mm.

2. Position the hob seal, as shown in the diagram below (Fig 8),

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 the following diagram (Fig 9).

Remove any excess sealant after tightening the brackets.
