Be safe
You need clean fresh air - so does your cooker. Burner flames produce exhaust
gases, heat and moisture. Make sure that the kitchen is well ventilated: keep
natural ventilation holes open or install a powered cooker hood that vents outside.
If you have several burners on or use the cooker for a long time, open a window or
turn on an extractor fan. For more detail see the Installation Instructions.
We recommend you read the ‘General Safety Instructions’ section if you have not
used a gas cooker before. We describe some basic guidelines on how to use a gas
cooker safely.
Gas and Electricity on
Make sure that the gas supply is turned on and that the cooker is wired in and
switched on.
The cooker needs electricity.
Peculiar smells
When you first use your cooker it may give off a slight odour. This should stop after
a little use.

Hotplate Burners
The drawing by each knob indicates which burner that
knob controls.
Push in and turn a knob to the large flame symbol ( ) and
press the igniter button or light with a match.
Adjust the flame height to suit by turning the knob. On
this cooker the low position is beyond high, not between
high and off. The small flame marks the ‘low position’.
Turn the knob towards it after the contents of a pan have
boiled.
Make sure flames are under the pans. Using a lid will help
the contents boil more quickly.
Pans and kettles with concave bases or down turned
base rims should not be used.
Simmering aids, such as asbestos or mesh mats, are
NOT recommended. They will reduce burner performance
and could damage the pan supports.
Avoid using unstable and misshapen pans that may tilt
easily and pans with a very small base diameter e.g. milk
pans, single egg poachers. The minimum pan diameter
recommended is 120mm (about 43/4").
The Wok burners are designed to provide even heat over
a large area. They are ideal for large pans and stir frying.
For heating smaller pans the smaller burners may be
more efficient.
When ignition button knob is pressed in,
sparks will be made at every burner, this is
normal.
If after lighting, a hotplate burner’s flame goes
out, turn it off and leave it for one minute before
relighting it.
You can remove the burner cap and trim
rings for cleaning, see pages 18/19.
You should wipe the enamel top surface of the
cooker around the hotplate burners as soon as
possible after spills occur. Try to wipe them off
while the enamel is still warm.
Avoid using unstable and misshapen pans,
which may tilt easily, and pans with a very
small base diameter, e.g. milk pans, single egg
poachers.
The minimum pan diameter recommended is
120mm (43/4"). Smaller pans will be unstable.
Pans and kettles with down turned base rims
should not be used.
Note:
Use of aluminium pans may cause metallic
marking of the pan supports. This does not
affect the durability of the enamel and may
be cleaned off with a metal cleaner such as
'Brasso'.

The Griddle
The griddle fits the left pan support, front to back. It is
designed for cooking food on directly. Don’t use pans of
any kind on it. The griddle surface is non-stick and metal
cooking utensils (e.g. spatulas) will damage the surface.
Use heat resistant plastic or wooden utensils.
Don’t put it on the centre Wok burner - it is not designed
to fit the Wok burner pan support and will be unstable.
Position the griddle over the hotplate burners resting on
the pan support.
Check that it is securely located.
The griddle can be lightly brushed with cooking oil before
use. Light the hotplate burners. Adjust the flame heights
to suit.
Preheat the griddle for a maximum of 5 minutes before
adding food. Leaving it longer may cause damage. The
controls can be turned to a lower position simply by
turning the control knobs towards the lower position
marked with the small flame symbol.
Always leave space around the griddle for the gases to
escape. Never fit two griddles side by side. Large pans
should also be spaced well apart.
Use the following heat settings as a guide for
griddle cooking.
High/medium:
Drop scones, Bacon, Chops, Steak, Burgers.
Medium/low:
Potato cakes, Eggs, Fish cakes.
Experience will soon familiarise you with the
correct setting to use for cooking.
After cooking allow the griddle to cool before
cleaning.
Don’t put it on a Wok burner - it is not designed
to fit the Wok burner pan supports.

The Wok cradle
The Rangemaster Wok cradle is designed to fit a
TyphoonTM Professional 14” Wok.
This is available from CookCraft (www.cookcraft.com) and
also from other retailers.
If you use a different Wok make sure that it fits the cradle.
Woks vary very widely in size and shape. It’s important
that the Wok sits down on the pan support - but if the Wok
is too small the cradle will not support it properly.
The cradle should be used on the triple ring Wok burner
only.
When you fit the cradle check that the Wok is properly
located on the front and rear fingers and that it is
supported properly on a pan support.
Make sure the cradle is stable and that the Wok is sitting
level in the ring.
The cradle will get very hot in use - allow plenty of
time for it to cool before you pick it up.
Care and Cleaning
Essential information
Never use paint solvents, washing soda, caustic
cleaners, biological powders, bleach, chlorine
based bleach cleaners, coarse abrasives or salt.
Recommended cleaning materials are hot soapy
water, a moistened soap pad, cream cleaner or
a nylon scourer.

The Grill
CAUTION: Accessible parts may be hot when
the grill is in use. Young children should be
kept away.
Remove the pan from the bottom of the grill compartment.
After placing your food on the grill tray pan, slide the grill
pan onto the side supports just below the elements. Make
sure it is pushed right in and touches the backstop.
The grill has two elements that allow either the whole
area of the pan to be heated or just the right hand half.
Turn the knob to position 3.
For best results preheat for 2 minutes with the grill pan in
position. After placing your food on the grill pan grid, slide
the grill pan onto the side supports. Adjust the heat to suit
by turning the knob.
Make sure it is pushed right in and touches the back
stop.
Never close the grill door when the grill is on.
5
The grill pan grid can be turned over to give two grilling
positions.
Don’t leave the grill on for more than a few
moments, without the grill pan underneath it.
For best results, especially with toast,
preheat the grill with the grill pan in the
cooking position for two minutes before use.
The grill trivet can be removed and the food
placed on it while you are waiting for the grill to
preheat.
The grill pan grid can be turned over to give
two grilling positions.
You can brown the top of dishes cooked in the
oven, under the grill by placing the dish onto
the base of the grill pan, which can easily slide
along the floor of the grill cavity.

The Ovens
During use the appliance becomes hot. Care should be taken to avoid the touching heating
elements inside the oven.
The clock must be set to the time of day before the ovens will work. See ‘The Clock’ section for
instructions on setting the time of day.
The Left Hand Oven The Right Hand Tall Oven
The left hand oven is a Multi-function oven. As well as
the oven fan and fan element, it is fitted with two extra
heating elements, one visible in the top of the oven and
the second under the oven base. Take care to avoid
touching the top element and element deflector when
placing or removing items from the oven. For more detail
on this oven see the section ‘Multi-function oven’.
The fan in the right hand oven circulates hot air
continuously, which means faster more even cooking.
The recommended cooking temperatures for a fanned
oven are generally lower than a non-fanned oven.
The Multi-function oven has two controls, a function
selector and a temperature setting knob..
The right hand fan oven control is at the right hand end
of the control panel.
Turn the function selector control to a cooking function.
This is the fan oven setting.
Turn the oven temperature knob to the temperature you
need.
Turn the oven temperature knob to the temperature you
need.
The oven heating light will glow until the oven has
reached the temperature you selected. It will then cycle
