Installation
The following instructions are intended for the installer so that the
installation and maintenance procedures may be followed in the
most professional and expert manner possible. Important:
Disconnect the appliance from the electrical supply before
performing any maintenance or repair.
Positioning the Hob
Important: this unit may be installed and used only in
permanently ventilated rooms in accordance with British
Standard Codes Of Practice: B.S. 6172 / B.S. 5440, Par. 2 and
B.S. 6891 Current Editions. The following requirements must be
observed:
a) The room must be fitted with a ventilation system which vents
smoke and gases from combustion to the outside. This must
be done by means of a hood or electric ventilator that turns
on automatically each time the hob is operated.
In a chimney stack or branched flue. Directly to the Outside
(exclusively for cooking appliances)
b) The room must have an air flow to allow for proper combustion.
This must be 2 m 3 ³/h per kW of installed power. The airflow can
be created using an enclosed vent with an inner cross section
of at least 100 cm² which must not be able to be blocked. I the
appliance does not have a flame failure device, the vent must
have an internal cross section of 200 cm
3 ³ (Fig. A). Alternatively
the room in which the hob is situated can be vented indirectly
through ventilation ducts as specified above, as long as the
adjacent room is not a shared area, a bedroom or present any
risk of fire (Fig. B).

c) Intensive and prolonged use of the appliance may necessitate
supplemental ventilation, e.g. opening a window or increasing
the power of the air intake system (if present).
d) Liquidified petroleum gases are heavier than air and, as a result,
settle downwards. Rooms in which LPG tanks are installed
must be fitted with ventilation openings to the outside in order to
allow the gas to escape in the event of a leak. Therefore, LPG
tanks, whether empty or partially full, must not be installed or
stored in rooms or spaces below ground level (cellars, ect.). It is
also a good idea to keep only the tank currently being used in
the room, making sure that it is not near sources of heat (ovens,
fireplaces, stoves, etc.) that could raise the internal temperature
of the tank above 50°C.
Installation of built-in hobs
The gas hobs are prepared with protection degree against
excessive heating of type X, the appliance can therefore be
installed next to cabinets, provided the height does not
exceed that of the hob. For a correct installation of the cooking
hob the following precautions must be followed:
a) The hob may be located in a kitchen, a kitchen/diner or
bed sitting room, but not in a bathroom or shower room.
b) The furniture standing next to the unit, that is higher than
the working boards, must be placed at least 110mm from
the edge of the board.
c) The cabinets should be positioned next to the hood at a
height of at least 420 mm (Fig. C).

d) Should the hob be installed directly under a cupboard,
the letter should be at least 700mm (millimetres) from the
worktop, as shown in Fig. C.
e) The dimensions of the room for the furniture must be those
indicated in the figures in the last two pages of the cover.
Fixing hooks are provided which allow to place the hob
plate on work tops that measure from 20 to 40 mm in
thickness (see Fig. D). To obtain a good fixing of the hob
plate it is advisable to use all the hooks supplied.
