The grill
The grill is a high-speed grill. The instructions below tell you how to vary
the heat setting and how to change the height of the grid to suit the food
you are cooking. You should remember to turn the food regularly.
You should not use the grill to keep food warm as it will continue to
cook the food.
Prior to using the grill
We suggest that you operate the grill for approximately 5 - 10 mins to
burn off any residue from the surface. During this period a slight odour
may be emitted, it is therefore advisable to open a window for
ventilation.
When you first operate the grill you may hear some sounds as the
burner heats up, this is quite normal and is not a fault on the appliance.
Heat control
The grill control gives two heat settings.
The control knob turns to the left from
'OFF' to 'HIGH' and then to 'LOW'. The high
setting should be used for fast cooking such
as toast. Use the low setting to cook thicker
food such as chicken after it has been
browned on the high setting.

Thegrill
For your safety
Never cover the grill pan or grid with foil as this can lead to grill
fires.

Cooking positions
Place the grill pan so that the bottom of the
handle fits into the hole on the shelf.
Most food should be cooked on the grid in
the grill pan. The grid can be turned over to
suit different thicknesses of food.
You can place some dishes straight on to
the grill shelf. This is useful when you are
browning the top of food such as cauliflower
cheese.
Preheating
You don't usually need to preheat the grill. You may wish to preheat it
for a couple of minutes when you are cooking steak or when browning
food.
Positioning food on the grid
Place food such as toast, teacakes and
muffins towards the centre of the grid.
Place food which needs a more gentle heat
such as tomatoes and mushrooms towards
the edge of the grid.
Arrange meat, meat products and fish to
suit their thickness and how you like them
cooked.

The hotplate
Heat control
The hotplate control knobs turn anticlockwise
from 'OFF' to 'HIGH' and then to 'LOW'. You
can adjust the heat by turning the control
between the highest and lowest settings.
These are shown as a large and a small
flame symbol.
Burner sizes
The hotplate has three burner sizes to suit
different types of cooking:
Largest burner (Rapid) - use a large pan for
food such as chips.
Medium burners (Normal) - use for everyday
cooking.
Small burner (Simmer) - use for simmering
food such as soups and stews.
The largest pan which you should use on any burner is 230mm (9").
The base of the smallest pan should not measure less than 100mm (4").
Lift pans on and off the pan supports. Do not slide them across
the hob.

For your safety
1 Take care to avoid burns and scalds when you
are reaching across the hotplate.
2 Use pans with flat bases. They are more stable
than pans which are warped.
3Do not use pans with very heavy handles which
cause the pan to tip.
4 Put pans on the centre of the burners.
5 Position pan handles so they cannot be
accidentally knocked.
6 Take extra care when you are deep fat frying. Do
not cover the pan with a lid.
Do not leave a pan unattended. If the pan
catches fire, leave it where it is and turn off all
controls.
Place a damp cloth or a fitting lid over the pan to
smother the flames.
Never put water on the fire.
Leave the pan to cool for 30 minutes.
7 If you are using a Wok we recommend it has a flat
base as it will stand stable on the pan supports. If
you use a round based Wok with a collar support,
the collar must be of the open wire work type. A
closed collar will affect the performance of the
burner. Before you use the Wok make sure that
the collar is stable on the pan supports. Always
follow the instructions that come with the Wok.

Helpful hints
1 Keep flames under the base of
pans. If the flames lick round the
sides of the pans you are wasting
gas.
2 Only heat the amount of liquid you
need. Do not overfill pans.
3 Cover pans with a lid whenever
possible. The food will heat up
more quickly and there will be less
steam in the kitchen.
4 Try cooking more than one
vegetable in the same pan, for
example potatoes and carrots.
5 Cut vegetables into smaller pieces.
This way they will cook more
quickly.
6 A pressure cooker will save time
and energy.

The oven
Before you use the oven you should wipe it out with a damp cloth to
remove any dust.
Heat zones
There are zones of heat within the oven.
The temperature in the middle is thegas
mark you have chosen. The top of the
oven is slightly hotter and the lower shelf
slightly cooler. The base of the oven is
quite a lot cooler. You can make use of
these heat zones when you are cooking
foods requiring different temperatures all at
the same time.
If you are cooking more than one tray of similar items, for example
cakes or biscuits, swap the trays during cooking or you can remove the
top tray when the food is cooked and move the lower tray to the higher
shelf to finish cooking.
Preheating
You do not need to preheat the oven when casseroling and so on.
Preheat the oven for baking or when you are cooking sensitive food
such as Yorkshire puddings, soufflés and yeast mixtures.
When you are cooking or reheating frozen or chilled food read the
instructions on the packing.
When you need to preheat the oven, we recommend you do so for
20 minutes.
Oven Shelves
You can slot the oven shelves in any of five
positions. Positions are counted from the top
downwards.
For safety the shelf will only pull out so
far. If you want to remove a shelf completely
pull it forward as far as it will go, raise the
front edge and lift it out. To put the shelf into
a different position keep the front edge
raised, slot the shelf on to the runner, lower
the front edge and slide the shelf in.

Baking trays and dishes
Leave a gap of 13mm (½") between
all dishes and the sides of the oven
so the heat can circulate properly.
Do not push dishes too far back as
food will burn if it overhangs the
burner flames.
For the best results we recommend that you use a baking tray which is
310mm (12") square. If you use a tray or tin which is larger than this,
you may need to turn it around during cooking.
Place single dishes on the centre of the shelf. You may need to turn
large items around during cooking.
Roasting
For best results we recommend open roasting using minimal fat or oil to
prevent splashing.
It is not necessary to cover meat or poultry or wrap food in foil when
roasting as this restricts the circulation of heat and will lead to extended
cooktimes.
If you are using a roasting bag or cover chicken breast with foil, be
prepared to allow an extra 10 - 15 minutes for each 1/2kg (1lb).
When cooking large items such as turkeys, the use of foil may be
required to prevent the breast becoming dry before the rest of the bird is
fully cooked.
Condensation
Condensation may form on the appliance. This is quite normal and
nothing to worry about. The condensation forms when heat and
moisture are present, for example during cooking. Whenever possible
try to make sure that food which contains a lot of moisture for example
casseroles are covered. If you do notice any condensation, wipe it up
straight away.

For your safety
Never place cooking dishes, trays
and so on over the oven burner.
This will damage the appliance as
well as the ovenware and possibly
the floor covering underneath the
appliance.

Oven cooking chart
These instructions are for cooking in the oven after it has been pre-heated for 20 minutes.
If you are cooking more than one tray of similar items, for example cakes or biscuits, swap the trays around during cooking or you
can take the top tray out of the oven when the food is cooked and move the lower tray to the higher shelf to finish cooking.
Always leave at least one shelf position between shelves to allow heat to circulate.
The recommended shelf positions give the best results.
Put the dishes in the centre of the shelf.
You can change the gas marks and cooking times to suit your own tastes.
It is important to check that food is piping hot before serving.

Slow cooking
The slow cook setting gives a very low heat in the oven. It is particularly
useful when you are cooking soups, stews and casseroles because
the long slow cooking will make cheaper, tougher cuts of meat more
tender.
You need to cook food at gas mark 6 for 30 minutes before you turn the
oven down to the slow cook setting. This makes sure that the
temperature of the food gets hot enough to start the food cooking.
Some foods such as pastry and biscuits are not suitable for slow
cooking because the temperature is too low.
Cover all food during cooking to prevent it from drying out. You can
uncover food for the last half hour if it is normally served golden brown.

General points for slow cooking
Frozen foods
Thaw thoroughly before cooking.
Thickening
Toss meat in flour for casseroles. Alternatively blend cornflour with
water and add it at the end of cooking.
Flavouring
Flavours are held in the food because there is little evaporation. Adjust
flavouring at the end of the cooking time.
Liquid
Use slightly less liquid as there is little evaporation during cooking.
Milk and milk products, for example cream
Add these towards the end of cooking to prevent them from curdling.

Reheating
Cool left over food quickly and then put it in the fridge. Do not reheat
food using the slow cook setting. Reheat food in the usual way or in a
microwave.
Only reheat food once.

Care and cleaning
Do not use any polishes, caustic cleaners, abrasives, washing soda
or soap powder except those recommended in this
booklet.
Please note: If we recommend you use hot
soapy water we mean hot water with washing up
liquid in it and not any other cleaning product.
If you own a dishwasher please read the
operating instructions for the machine before you
wash any part of your appliance in it.
Clean your appliance regularly using a cloth that has been wrung out
in hot soapy water. Rinse and polish it dry using a soft cloth.
When you remove parts of your appliance for cleaning do not plunge
them into water whilst they are very hot as this may damage the finish of
the parts.
Cleaning the brass plated handle (Where applicable)
It is strongly recommended that only hot soapy water is used for
cleaning the door handle. ANY OTHER CLEANING MATERIALS WILL
DULL THE BRASS PLATED FINISH.
The hotplate
Clean the hotplate top using a mild abrasive such as 'Cif'. You can
remove the pan supports, burner caps and burner crowns to clean
them. If any food spills do occur during cooking you can place the pan
on another burner to finish cooking. Then you can remove the dirty
parts and clean them before the spill 'burns on'.
You can wash the removable parts in very hot soapy water. You may
use mild abrasives. Make sure that the hole and slots in the crown are
not blocked with food or cleaning materials.
Clean the burner crowns by soaking them in very hot soapy water. You
can remove any stubborn stains by scouring with a soap filled pad such
as 'Brillo'. If you look after the burner crowns in this way they will stay
reasonably clean. However the surface will dull with time.
LIBRA 3

For your safety
For hygiene and safety reasons you must keep this gas appliance
clean. A build up of fat or other foodstuff could cause a fire.
Try to mop up spills and splashes as soon as they happen. But
be careful as parts of the appliance will be hot.
Careandcleaning

Aluminium based saucepans can leave shiny metal marks on the pan
supports. To clean the pan supports regularly remove the marks using a
mild abrasive like 'Cif' with a soft scourer. For more stubborn marks you
can use a soap filled pad such as 'Brillo'.
After cleaning the appliance parts, dry them
thoroughly before you put them back.
When replacing hotplate burner parts
1. Crown to body (Do not try to force the crown on to the body).
Check that the two longer location pegs
sit in the slots in the body. When the
crown is in this position let it fall freely on
to the body.
Check that the crown can be moved
slightly from side to side.
2. Cap to crown
Place cap centrally on the top of crown
(enamel side up). Move sideways and
front to back to check the cap is fitted
properly.
3. Check that the burner lights
If a burner will not light then you need to
check the crown and cap positions.
The grill
Do not clean the grill burner itself.
The burner is designed to be self cleaning. Cleaning the grill may cause
the holes in the burner to become blocked preventing it from operating
correctly.
Please note that due to the nature of stainless steel the grill burner may
tarnish through use over a period of time. This is quite normal and is not
a fault on the appliance.
Clean the area around the grill frequently using hot soapy water.
After use you can soak the pan for a few minutes and then clean it using
mild abrasives or a soap filled pad such as 'Brillo'.
Clean the grill shelf using hot soapy water. Mild abrasives can be used
if necessary.
