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:

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 in accordance with the dimensions
given in Fig.6 on page 17 of this manual 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.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 65°C above ambient or greater
(typically 80-90°C).
• The rear wall or splashback the hob is to be fitted in front of must be
made of a flame resistant material.
• 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: HVG621 = 595mm (W) x 515mm (D)
HVG721 = 700mm (W) x 515mm (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 hob cut-out (Fig 6) shows
a minimum 50mm gap from the rear wall or splashback to the cut-
out edge.
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.
