INTRODUCTION GB
This appliance must be installed in accordance with the local, national and European
regulations in force. Particular attention shall be given to the requirements regarding
ventilation. Read the instructions before installing or using the appliance
The appliance is designed for either high or low level installations. Failure to install the
appliance correctly could invalidate any warranty or liability claims and lead to prosecution.
Please refer to the methods of installation within this handbook.
Our policy is one of continuous development and improvement. Specifications and
illustrations may change subsequent to publication.
Provision Of Ventilation
The use of a gas cooking appliance results in the production of heat and moisture in a room in
which it is installed. Ensure that the kitchen is well ventilated, keep natural ventilation holes
open or install a mechanical ventilation device (mechanical extractor hood).
Prolonged intensive use of the appliance may call for additional ventilation, for example
opening a window, or more effective ventilation, for example increasing the level of
mechanical ventilation where present. The room containing the appliance should have an air
supply in accordance with local, national and European standards.
Position
This appliance must be positioned free from draughts, which may affect the combustion and
in a manner that will prevent the accumulation of unburnt gas. When in use ensure that air
vents are not inadvertently blocked or shut off.
We recommend that all ventilation holes in the appliance cabinet are baffled, to prevent direct
draughts on the appliance.
•Before using the appliance for the first time, remove all accessories and
packing in the grill and oven, including any plastic surface protection film.
•Clean all surfaces with hot soapy water to remove any residual
protective covering of oil and rinse carefully.
OPERATION
The burners on this appliance have fixed aeration and no adjustment is required. The burners
should flame as follows:-
Propane -The flames should burn quietly with a blue/green colour with
no sign of yellow tips.
Butane - Normally on initial lighting, a small amount of yellow tipping
will occur. This then increases slightly as the burner heats up
Using the Hotplate Gas Burners
1. Ensure gas cylinder/supply is connected and turned on. In the event of a gas smell turn off
at gas cylinder/mains and contact supplier.
2. Flame supervision: Each burner is controlled individually and is monitored by a
thermocouple probe. In the event of the burner flames being accidentally extinguished,
turn off the burner control and do not attempt to re-ignite the burner for at least one
minute.
6

OPERATION
3. To light: Push in the control knob and turn to full rate – see Fig.1. Hold a lighted match or
taper to the burner and push the control knob in and hold. It is necessary to hold the knob
depressed after the burner has ignited for approximately 10 - 15 seconds, to allow the
thermocouple probe to reach temperature, before releasing the knob. Should the flame go
out when the knob is released, the procedure should be repeated holding the knob
depressed for slightly longer.
4. For models fitted with Spark Ignition the procedure is similar except that the burner can be
ignited by depressing the ignition button, which is located on the fascia. If the burner has
not lit within 15 seconds the control knob should be released and the burner left for at
least 1 minute before a further attempt to ignite the burner.
5. For simmering, turn the knob further anti-clockwise to the low rate position.
6. To turn off: Turn the control knob until the line on the control knob is aligned with the dot
on the control panel. Always make sure the control knob is in the off position when you
have finished using the hotplate burners
•Each burner will support pans from Ø10 to Ø22cm, care should be taken
not to overload the appliance as performance may be reduced.
•The following pan sizes are the maximum we recommend:-
Electric Hotplate:- Ø180mm
Auxiliary Burner:- Ø200mm
Semi-Rapid Burner:- 2x Ø200mm or 1x Ø220mm with 1x Ø180mm
•When using small pans the flames should not spread beyond the base of
the pan as this will reduce the efficiency of the burner.
•Avoid old or misshapen pans as these may cause instability.
•The lid must be opened fully prior to using the hotplate burners.
Using the Electric Hotplate
Ensure the electricity is switched on. The hotplate control is numbered from 1 to 6. To turn it
on, rotate the knob either clockwise or anti-clockwise to the required position. Position 1 is the
coolest setting. To turn off, rotate the knob until the line or pointer on the knob lines up with
the zero on the control panel.
The hotplate is a sealed construction and transfers heat through conduction. For maximum
efficiency a correctly sized pan with a flat heavy gauge base should be used. Pan size should
be the same or slightly larger (up to 1” / 2.5cm oversize).
Before using your hotplate for the first time, we recommend that you prime and season it.
To prime the Hotplate
Switch on the hotplate for a short period, without a pan, to harden and burn off the coating.
Use a medium to high setting for 3 – 5 minutes. A non toxic smoke may occur during this
process. Allow it to cool, then season.
To season the Hotplate
First heat the hotplate for 30 seconds on a medium setting, then switch off. Pour a minimal
amount of unsalted vegetable oil onto a clean dry cloth or paper towel, and apply a thin coat
of oil to the hotplate surface. Wipe off any excess oil, then heat the hotplate on a medium
setting for 1 minute. Occasional seasoning will help to maintain the Hotplate’s appearance.
•Depending on specification, your appliance may be fitted with a glass lid
shut-off system, which cuts off the power to all hotplate burners (gas and
electric) if the lid is closed.
•Ensure the glass lid is open before turning on the hotplate burners.
7

OPERATION
•Children should be supervised to ensure they do not play with the
appliance
•Glass lids may shatter when heated. Turn off the hotplate and allow it to
cool before closing the glass lid.
•Remove all spillage from the surface of the glass lid before opening.
•The glass lid has the tendency to snap shut towards the end of lowering.
This is caused by the travel lock action of the hinges as it is activated.
Make sure all fingers are removed from appliance when closing the lid.
Using the Grill
1. Ensure gas cylinder/supply is connected and turned on. In the event of a gas smell turn off
at gas cylinder/mains and contact supplier.
2. To light: Open door, push in the control knob and turn to full rate – see Fig 1. Hold a
lighted match or taper to the burner and push the control knob in and hold. The burner
should ignite and the control knob should be held in for 10 -15 seconds before release. If
the burner goes out, repeat procedure holding control knob for slightly longer.
3. For models fitted with Spark Ignition the procedure is similar except that the burner can be
ignited by depressing the ignition button, which is located on the fascia. Ignition must be
carried out with the door open, and if the burner has not lit within 15 seconds the control
knob should be released and the grill left for at least 1 minute before a further attempt to
ignite the burner.
4. Note: the grill must only be used with the door open.
5. On first use of the grill, it should be heated for about 20 minutes to eliminate any residual
factory lubricants that might impart unpleasant smells to the food being cooked. A non-
toxic smoke may occur when using for the first time so open any windows and turn on
mechanical ventilators to help remove the smoke.
6. Although the grill does heat up quickly, a few minutes preheat is recommended.
7. Flame Failure Device (FFD): the grill burner is fitted with a flame sensing probe, which will
automatically cut off the gas supply in the event of the flame going out. In the event of the
burner flames being accidentally extinguished, turn off the burner control and do not
attempt to re-ignite the burner for at least one minute.
8. It is normal for the flames on this burner to develop yellow tips as it heats up.
9. A reversible grill pan trivet enables the correct grilling height to be achieved.
Fast Toasting trivet in high position
Grilling Sausages trivet in high position
Grilling Steak/Bacon trivet in high position
Grilling Chops, etc trivet in low position
Slow Grilling trivet removed
10. To turn off: turn the control knob until the line on the control knob is aligned with the dot on
the control panel. Always make sure the control knob is in the off position when you have
finished grilling.
•The grill area can get hot when the oven is in use, even if the grill is
switched off.
•Care should be taken when removing pans from the grill, i.e. use of oven
gloves, and by making use of the removal grill pan handle.
•The grill pan supplied is multi functional, for use in grill or oven.
•The handle design allows removal or insertion whilst the pan is in use.
•Always remove the handle when the pan is in use.
•The grill MUST only be used with the door open.
8

OPERATION
•The appliance is fitted with a cooling system. The cooling fans will
automatically switch on a few minutes after the grill and/or oven is turned
on, and will remain on even after the appliance has been switched off.
•The fans will automatically switch off a few minutes after the appliance
has been switched off, when the front of the appliance has cooled
sufficiently.
•A constant 12V supply is necessary at all times to ensure the cooling
system operates correctly.
Using the Oven
1. Ensure gas cylinder/supply is connected and turned on. In the event of a gas smell turn off
at gas cylinder/mains and contact supplier.
2. To light: Open door, push in the control knob and turn to full rate (240°C). Hold a lighted
match or taper to the burner and push the control knob in and hold. The burner should
ignite and the control knob should be held in for 10 -15 seconds before release. If the
burner goes out, repeat procedure holding control knob for slightly longer.
3. For models fitted with Spark Ignition the procedure is similar except that the burner can be
ignited by depressing the ignition button, which is located on the fascia. Ignition must be
carried out with the door open, and if the burner has not lit within 15 seconds the control
knob should be released and the oven left for at least 1 minute before a further attempt to
ignite the burner.
4. Place the oven shelf in the required position and close the door.
5. Set the control knob to required temperature. Although the oven heats up quickly, it is
recommended that a 10 minute preheat be allowed. The oven should be up to full
temperature in about 15-20mins.
6. To turn off: turn the control knob until the line on the control knob is aligned with the dot on
the control panel.
7. Shelf: the shelf has been designed to allow good circulation at the rear of the oven and is
also fitted with a raised bar to prevent trays or dishes making contact with the back of the
oven. To remove a shelf, pull forward until it stops, raise at front and remove.
•Before first use, heat the oven for about 30 minutes at 200oC, to eliminate
any residual factory lubricants that might impart unpleasant smells to the
meals being cooked. A non-toxic smoke may occur when using for the first
time so open any windows and turn on mechanical ventilators to help
remove the smoke.
•The pans and trays supplied with this appliance are the maximum sizes
recommended for use. Larger pans and trays may restrict good
circulation of heat, increasing cooking times.
•Always ensure food is properly cooked prior to serving.
Oven Temperature Control
The temperature in the oven is controlled by a thermostatic gas tap and is variable over the
range 130°C to 240°C. Approximate temperatures for the settings on the control knob are
shown in the table below. The temperatures indicated refer to the centre of the oven and at
any particular setting the oven will be hotter at the top and cooler towards the base.
The variation between top and centre, and centre to bottom is approximately equivalent to
one gas mark. Good use can be made of the temperature variation in several dishes requiring
different temperatures may be cooked at the same time. In this way maximum benefit can be
obtained from the gas used to heat the oven. Care should be taken not to overload the oven,
adequate spacing being used to allow free circulation for heat.

Cooking Guidelines
Best results will be obtained by the shelf positions in this guide. Although the oven heats up
quickly, it is recommended a 10 minute preheat be allowed. The oven should reach full
temperature in 15-20 minutes.
Most cookery books give details of the shelf positions and gas mark settings for each recipe.
If in doubt about a recipe you intend to use, study the recipe carefully then find a similar dish
in our guide and use our shelf position and gas mark setting recommendation. Shelf positions
are from the top down. When roasting with aluminium foil care must be taken that the foil
does not impair circulation or block the oven flue outlet.
