precautions that must be observed.

PLEASE READ THE BELOW PRECAUTIONS BEFORE USING YOUR APPLIANCE.

To maintain the efficiency and safety of this appliance, we recommend you do the following:

- only call the Service Centres authorised by the manufacturer.

- always use genuine spare parts.

ALWAYS:

- make sure you remove all packaging and dispose of safely.

- check the soundness of the appliance after it has been
unpacked.

- make sure you understand the controls before using the
appliance.

- keep children away from the appliance during use.

- take care to avoid heat/steam burns when operating the
controls.

- make sure the controls are turned off when you have finished
cooking and when not in use.

- take care to avoid heat/steam burns when operating the
controls.

- disconnect from the power supply, and allow to cool, before
cleaning or performing maintenance.

- refer servicing to a qualified appliance service engineer.

- keep the hob clean as a build up of grease or fat from
cooking can cause a fire.

- follow the basic principles of food handling and hygiene to
prevent the possibility of bacterial growth.

- dry food thoroughly before frying and lower it slowly into the
hot oil or fat. Frozen food in particular, will cause frith and
spitting if added too quickly.

- keep outside of pans clean and free from streaks of oil or
fat.

- place pans centrally over the burner making sure handles
are kept away from the edge of the hob and cannot be
heated by other burners/pans.

- keep any ventilation slots clear of obstructions.

NEVER:

- attempt to install or repair the appliance without the
assistance of qualified personnel.

- store items above the appliance that children may attempt
to reach.

- heat up unopened food containers, as pressure can build
up causing the container to burst.

- use the appliance to heat up anything other than food.

- use the appliance as a room heater.

- dry any items on the hob.

- install the appliance next to curtains of other soft furnishings.

- allow children to play with or tamper with the controls.

-leave children unsupervised where cooking appliances are
installed as all the cooking surfaces get hot during and after
use.

- store chemicals, foodstuffs or pressurised containers in or
on the appliance, or in cabinets immediately above or next
to the appliance.

- use flammable or plastic items on or near the hob.

- use adapters, multiple sockets and/or extension leads.

- fill a deep fat frying pan more than 1/3 full of oil, or use a lid.
DO NOT LEAVE UNATTENDED WHILE COOKING.

- fry too much food at a time, especially frozen food. This
only lowers the temperature or the oil or fat too much, resulting
in greasy food.

- pull on the appliance or the supply able to unplug it from
the electrical outlet.

- allow power cables of other appliances to come into contact.

- with hot parts of this appliance.

- expose the appliance to atmospheric agents, such as
rain or sunlight.

- operate the appliance with wet hands.

- allow anyone to sit or stand on any part of the appliance.

- use misshapen pand which may be unstable.

- use round base woks directly on the pan supports.

- use fish kettles or large preserving pans across two burners.

SAFETY ADVICE

IMPORTANT - As with any cooking appliance there could be some fire risk attached to the heating of oil, particularly for
deep fat frying. Cooking utensils containing oil must not be left unattended (eg. to answer the telephone) on or in close
proximity to the cooking areas.

IN THE EVENT OF A CHIP PAN OR ANY OTHER PAN FIRE:

1. Turn off the burners.

2. Cover the pan with a fire blanket or damp cloth, this will smother the flames and extinguish the fire.

3. Leave the pan to cool for at least 60 minutes before moving it. Injuries are often caused by picking up a hot pan and
rushing outside with it.

NEVER USE A FIRE EXTINGUISHER TO PUT OUT A PAN FIRE as the force of the extinguisher is likely to tip the pan
over. Never use water to extinguish oil or fat fires.

Installation Instructions for your built-in Hob

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 regulation
upkeep work.

Positioning for gas hob
Important: this unit may be installed and used only in

permanently ventilated rooms according to the British
Stancards 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 hob must not be installed in a bed sitting room with

a volume of less than 20m3. If it is installed in a room of
volume less than 5m3 an air vent of effective area of
110cm2 is required, if it is installed in a room of volume
between 5m3 and 10m3 an air vent of effective airvent of
50cm2 is required, while if the volume exceeds 11m3 no
airvent is required. However, if the room has a door or a
window which opens directly to the outside no air vent is
required even with the volume is between 5m3 and 11m3.

b) Intensive or prolonged use of the appliance could mean

that extra ventilation is needed, such as the opening of
a window or a more powerful fan.

c) If there are other fuel burning appliances in the same

room, B.S. 5440 Part 2 Current Edition, should be
consulted to determine the requisite air vent
requirements.

Installation of built-in gas 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 worktops, must be placed at least 110mm from the
edge of the board.

c) The minimum distance combustible material can be

fitted above the hob in line with the edges of the hob is
420mm. If is fitted below 420mm a space of 50mm
must be allowed from the edges of the hob. The
minimum distance combustible material kitchen units
can be fitted directly above the hob is 700mm.

Installation Instructions for your built-in Hob

When installing the hob above a built-in oven without forced
ventilation, ensure that there are air inlets and outlets for
ventilating the interior of the cabinet adequately.

Gas Connection for Cooktop

The hob should be connected to the gas supply by an
authorized installer. During installation of this product it is
essential to fit an approved gas tap to isolate the supply
from the appliance for the conv enience of any subsequent
removal or servicing. Connection of the appliance to the
gas mains or liquid gas tanks must be carried out
according to the safety standards currently in force, and
only after it is ascertained that it is suitable for the type of
gas to be used. If not, follow the instructions indicated in
the section entitled, “Adapting the hob for Different Types of
Gas”. If the hob is to be connected to tanks containing liquid
gas, use pressure regulators that comply with current safety
standards.
Important: To insure that the appliance operates safety,
the gas is regulated correctly and your appliance lasts
over time, make sure that gas pressure levels comply with
the indications given in Table 1, “Nozzle and Burner
Specifications”.

Gas Connection to Non-flexible Pipe

(copper or steel)
Connection to the gas source must be done in such a way
as to not create any stress points at any part of the
appliance.
The appliance is fitted with an adjustable, "L" shaped
connector and a gasket for the attachment to the gas supply.
Should this connector have to be turned, the gasket must
be replaced (supplied with the appliance).
The gas feed connector to the appliance is a threaded,
male 1/2" connector for round gas pipe.

Gas Connection to Flexible Steel Pipe

The gas feed connector to the appliance is a threaded, male
1/2" connector for round gas pipe. Only use pipes, tubes
and gaskets that comply with current safety codes. The
maximum length of the flexible pipes must not exceed 2000
mm. Once the connection has been made, ensure that the
flexible metal tube does not touch any moving parts and is
not crushed.

Check the Seal

Once the hob has been installed, make sure all the
connections are properly sealed, using a soapy water
solution. Never use a flame.

Adapting the Hob for Different Types of Gas

To adapt the hob to a different type of gas than that for
which it was designed, (see the sticker under the hob or on
the packaging), the burner nozzles must be changed, as
follows:

• Remove the pan supports and slide the burners out of

the hob.

• Unscrew the nozzles using a 7mm socket wrench and

replace them with those for the new type of gas. (See
Table 1, “Burner and Nozzle Specifications”).

• Reassemble the parts following the instructions in

reverse order.

• On completing the operation, replace the old rating label

with the one showing the new type of gas; the sticker
is available from our Hotpoint Service (see KEY

CONATCTS, back page).
If the gas pressure is different than that prescribed, a
pressure regulator must be installed at the source, in
compliance with national standards governing the use of
piped gas regulators.

Regulation of Air Supply to the Burner

The burners do not need a primary air regulator.

Minimum Regulation

• T urn the gas valve to minimum.

• Remove the knob and turn the regulator screw

(positioned either on the side of the top or inside the

shaft) clockwise until the flame becomes small but

regular.

N.B.: In the case of liquid gas, the regulation screw must be
fully screwed in (clockwise).

• Make sure that, when the knob is turned rapidly high

to low , the flame does not go out.

• In the event of a malfunction on appliances with the

security device (thermocouple) when the gas supply

is set at minimum, increase the minimum supply levels

using the regulator screw.
Once the adjustment has been made, apply sealing wax,
or a suitable substitute, to the old seals on the by-pass .
