INTRODUCTION
This appliance is designed for cooking foods, any other use is incorrect and may be
dangerous. Failure to install the appliance correctly or improper use will invalidate any
warranty or liability claims.
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
MUST be installed by an approved component person.
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, moisture and products of
combustion in the 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.
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
The burners are controlled individually, and each is monitored by a thermocouple probe. In
the event the burner flames are accidentally extinguished, turn off the burner control and do
not attempt to re-ignite the burner for at least one minute.
•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
Using the Hotplate Gas Burners
1. Ensure gas supply is connected and turned on.
2. Push in the control knob and turn anticlockwise to full rate –large flame ( ), see Fig 1.
3. Continue depressing the knob whilst holding a lighted match or taper to the burner.
For models fitted with spark ignition the procedure is similar except that burner is
ignited by depressing the ignition button located on the fascia.
4. After the burner is lit continue depressing the knob for approximately 10 - 15 seconds.
5. Release knob and turn to required heat setting.
6. If burner has not lit within 15 seconds, release knob and wait at least 1 minute before
repeating operations (2) to (5).
7. To turn off, rotate the control knob until the line on the knob is aligned with dot on the
control panel. Always make sure the control knob is in the off position when you have
finished using the hotplate burners.
8. For all-gas models, the maximum permitted pan sizes are 2 x 200mm Ø at the rear and
2 x 180mm Ø at the front. For dual fuel models the maximum pan size for the electric
hotplate is 180mm Ø. Ensure that a minimum 10mm gap is maintained between the
pans and the perimeter of the hob.
9. Avoid old, damaged or misshapen pans as they may cause instability. The glass lid
must be opened fully prior to using the hotplate burners.
Using the Electric Hotplate
1. Ensure the electricity is switched on.
2. The hotplate control is numbered from 1 (Low) to 6 (High). To turn on, rotate the knob
either clockwise or anti-clockwise to the required position.
3. 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 than the hotplate, (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. 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.

OPERATION
Using the Grill
Grill Door Warning Label
“CAUTION! Hot surfaces; Refer to the instruction manual; The grill door must be open when
the grill is in use.
1. Ensure gas cylinder/supply is connected and turned on.
2. Open the grill door, push in the control knob and turn anti-clockwise to large flame
symbol ( ).
3. Continue depressing the knob whilst holding a lighted match to the burner.
For models fitted with spark ignition the procedure is similar except that burner is
ignited by depressing the ignition button located on the fascia.
4. After the burner is lit continue depressing the knob for approximately 10 - 15 seconds
before releasing the knob.
5. If burner has not lit within 15 seconds, release knob and wait at least 1 minute before
repeating operations (2) to (4).
6. To turn off, rotate the control knob until the line on the knob is aligned with dot on the
control panel.
7. Always make sure the control knob is in the off position when you have finished grilling.
8. The grill door must always be open when the grill is in use.
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. Smoke may
occur when using for the first time, open any windows and turn on mechanical ventilators to
help to disperse the smoke.
Although the grill heats up quickly, it is recommended that a few minutes preheat be allowed.
Depending on the food to be cooked the correct grilling height can be achieved by inverting
the pan trivet into either the high or low position. It is normal for the flames on this burner to
develop yellow tips as it heats up.
OPERATION
•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 grill door open.
•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 to ensure the cooling
system operates correctly.

11
OPERATION
Using the Oven
1. Ensure gas cylinder/supply is connected and turned on.
2. Open the door, push in the control knob and turn to full rate (Gas Mark 9, 240°C).
3. Continue depressing the knob whilst holding a lighted match or taper to the burner.
4. After the burner is lit continue depressing the knob for approximately 10 - 15 seconds.
5. Release the knob and turn to required heat setting.
6. If the burner has not lit within 15 seconds, release knob and wait at least 1 minute
before repeating operations (2) to (5).
7. Place the oven shelf in the required position and close the door.
8. Although the oven heats up quickly a 10minute preheat is recommended. The oven
should reach full temperature in about 15-20mins.
9. To turn off, rotate the control knob until the line on the knob is aligned with dot on the
control panel.
10.Always make sure the control knob is in the off position when you have finished.
For models fitted with Spark Ignition the procedure is similar except that the burner can be
ignited by depressing the ignition button located on the fascia. Ignition must be carried out
with the door open.
The oven shelf has been designed to allow good circulation at the rear of the oven. A raised
bar at the rear of the shelf prevents trays or dishes contacting the back of the oven. To
remove a shelf, pull forward until it stops, raise at front and remove. Installation of a shelf is
the reverse of this procedure.
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. The table below provides a guide to the approximate temperatures at
each of the shelf positions with respect to the gas mark setting.
Good use can be made of the temperature variation between the shelf positions 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, allow adequate spacing to ensure free
circulation of heat. When roasting with aluminium foil ensure the foil does not impair
circulation of heat or block any oven flue outlet.
Before first use we recommend heating the oven for about 30 minutes at 200oC,
to eliminate any residual factory lubricants that might impart unpleasant smells to
the meals being cooked. Smoke may occur when using for the first time. Open
any windows and turn on mechanical ventilators to help disperse 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.

To reduce energy use on the hob whilst cooking.
Use the correct size of pan –a pan which fits the hotplate will use less energy than one that is
too large or too small.
Use the minimum heat setting to maintain simmering or boiling –additional heat is just wasted.
Cover pans or kettles with a lid whenever possible –this helps to retain heat.
Do not use old, damaged or distorted pans, they will reduce efficiency.
Do's and Don'ts
DO Read the user instructions carefully before using the appliance for the
first time.
DO Allow the burners to heat before using for the first time, in order to expel
any smells before the introduction of food.
DO Clean the appliance regularly.
DO Remove spills as soon as they occur.
DO Always use oven gloves when removing food shelves and trays from
the oven.
DO Check that controls are in the off position when finished.
DO NOT Allow children near the cooker when in use. Turn pan handles away
from the front so that they cannot be caught accidentally.
DO NOT Allow fats or oils to build up in the oven trays or base.
DO NOT Use abrasive cleaners or powders that will scratch the surfaces of the
appliance.
DO NOT Under any circumstances use the oven as a space heater.
DO NOT Put heavy objects onto open grill and oven doors.

other than cleaning. After the unit has cooled all parts should be cleaned using warm soapy
water. Do not use abrasive cleaners, steel wool or cleansing powders. When cleaning the
burner ring it is essential to ensure that the holes do not become blocked. The control knobs
are a push fit and can be removed for cleaning. They are interchangeable without affecting
the sense of operation.
INSTALLATION
Regulations and Standards
In your own interest of safety, it is law that all gas appliances are installed and serviced by a
competent registered person who will undertake to work to safe and satisfactory standards.
Failure to install the appliance correctly could invalidate any warranty or liability claims and
lead to prosecution. This appliance shall be installed in accordance with the local and
National/European standards in force. Particular attention shall be given to the requirements
regarding ventilation. Read the instructions before installing or using this appliance.
Ventilation
This appliance is suitable for installation into Holiday Homes, Touring Caravans and Boats. In
all cases the national standards regarding ventilation for the particular vehicle into which the
appliance is to be installed must be adhered to.
The European Standard EN1949 - "Specification for the installation of LPG systems in leisure
and other road vehicles", specifies appliances be installed in accordance with the
manufacturer’s instructions, including the adequate provision to avoid the accumulation of un-
burnt gases. We recommend a gas dispersal hole venting to the outside, with minimum size
Ø12mm, maximum Ø25mm, which should be baffled to prevent direct draughts to the
appliance.
Location of Appliance
This appliance maybe installed in a kitchen/kitchen diner but NOT in a room containing a bath
or a shower. LPG appliances must not be fitted below ground level. e.g. in a basement.
To ensure correct operation and prevent changes in air pressure affecting oven
performance we recommend the following installation requirements: -
•Built into self contained cabinet which is not connected to externally
vented chambers in adjacent furniture, other than correct size gas
dropouts.
•The installation must ensure free exchange of air between enclosure and
living environment.
•Holes for cables & pipes have minimum clearance where possible
•A gas dispersal hole shall be fitted, this must not exceed 1960mm2
•Cupboards below appliance must not allow gas to enter the living area.
•Air vents and gas dispersal holes shall be kept clear.

14
INSTALLATION
Position
A cut-out should be prepared as shown in the enclosed diagram –Fig. 3. The location of the
cut-out shall comply with the dimensions shown and include a gas dispersal hole venting to
the outside, indicated by in the diagrams. We recommend the dispersal hole is baffled
and positioned close to the front of the appliance. If this is not possible due to design
constraints the dispersal hole should be located at the rear. Do not locate the dispersal hole
directly below the oven burner. A warning notice located near the dispersal hole with the
following text is recommended. WARNING
Under no circumstances should the gas dispersal hole be obstructed.
A horizontal distance of 200mm must exist between the edge of the burners and combustible
material unless protected by a layer of non-combustible material. Unless the appliance is
fitted with a glass lid a non-combustible heat shield (splash back) must be fitted onto the rear
wall directly behind the appliance. For models with a glass lid, the distance from the edge of
the burner to the rear wall can be reduced to 110mm.
All combustible materials such as curtains and shelves must be kept well clear of the
appliance. Any fitments such as a cupboard above the appliance must have a minimum
clearance of 500mm between the fitment and the top of the pan support –see Fig. 2
The appliance should be fixed in place using the fixing screw positions located on either side
of the front trim (2 in the grill opening, 2 in the oven opening and 2 at base of oven opening)
and each hob side trim. Make sure the appliance is located correctly in the aperture prior to
final fixing.
The performance of this appliance meets the requirements of the European Standard for
Domestic Cooking Appliances (EN30) which specifies a maximum allowable temperature rise
of the furniture into which the appliance is installed of 65oC above the ambient temperature. It
is important the installer verifies the furniture construction material and that it is suitable for
the application - i.e. plastic materials used in the construction may have a softening point
lower than the maximum allowable temperature rise specified in the European Standard.
We recommend the installation follows the minimum dimensions shown in this manual as any
deviation could result in excessive temperature rise. If minimum dimensions must be reduced,
due to design constraints, a temperature rise test of all furniture fitted around the unit MUST
be performed. The design is deemed permissible providing the results of this test comply with
the allowable temperature rise specified above and with all standards in force. In addition
comply with all requirements detailed within the furniture manufacturer’s material
specification. Where minimum dimensions are reduced we recommend protecting with non
combustible material.
On completion of the installation a warning notice complying with EN721 Annex A should be
affixed adjacent to the appliance.
