Operation of the Door
This appliance is fitted with our unique slide under door. As you open the door fully, it
slides neatly under the oven. This feature maximises the space in the kitchen area by
reducing the protruding door, giving easy access to the inside of the oven.
To open the door:-
1. Pull the handle forward and down, as with any other drop down door
2. When in fully open position push the door horizontally to slide the door in.
3. Continue pushing until door stops in the parked position below the oven.
To close the door
4. Grasp handle and slide door out from parked position.
5. Continue until door fully extended.
6. Rotate door upwards into the closed position.
Operation
The burners on this appliance have fixed aeration and no adjustment is required. The
burners should flame quietly with a blue/green colour with no sign of yellow tips.
On the SD Duplex model the single control tap operates both the grill and oven burners.
To ensure safe operation it is not possible to operate both burners at the same time.
The burners on all SD models are controlled individually and each is monitored by a
thermocouple probe (FFD). 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.
Using the Grill
1. Ensure gas supply is connected and turned on.
2. To light: Open door and slide under, push in the control knob and turn clockwise to
full rate – large flame on control knob () Fig. 1.
3. Continue holding the knob depressed whilst holding a lighted match or taper to the
burner. 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.
4. After the burner is lit continue depressing the knob for approximately 10 - 15
seconds before release.
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 anti-clockwise until the circle on the knob is
aligned with the dot on the fascia panel.
OPERATION
WARNING
Pans or utensils MUST NOT be placed on the door when in its open position.

8
Using the Grill - cont.
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.
Although the grill does heat up quickly, it is recommended that a few minutes preheat be
allowed. It is normal for the flames on this burner to develop yellow tips as it heats up.
Grilling should be carried out with the grill pan on the middle shelf position. 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
The grill MUST only be used with the door open.
Using the Oven
1. Ensure gas supply is connected and turned on.
2. To light: Open door and slide under, push in the control knob and turn anti-clockwise to
full rate – Mark 9 on control knob Fig. 2.
3. Continue holding the knob depressed whilst holding a lighted match or taper to the
burner. 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.
4. After the burner is lit continue depressing the knob for approximately 10 - 15 seconds
before release.
5. If burner has not lit within 15 seconds, release knob and wait at least 1 minute before
repeating operations (2) to (4).
6. Place the oven shelf in the required position and close the door. Rotate the control
knob to the required gas mark 5 setting. Although the oven does heat up quickly, it is
recommended that a 10 minutes preheat be allowed. The oven should be up to full
temperature in about 15-20mins.
OPERATION
WARNING
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.
IMPORTANT
•The appliance is fitted with a fan cooling system. The cooling fan will
automatically switch on after lighting the grill or oven burner.
•The fan will automatically switch off a few minutes after the burner is
extinguished, when the front of the appliance has cooled sufficiently.

7. To turn off: turn the control knob clockwise until the circle on the control knob is aligned
with the dot on the control panel.
8. To remove a shelf, pull forward until it stops, raise at front and remove.
On first use of the oven, it should be heated for about 30 minutes at gas mark 5 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.
Oven Temperature Control
The temperature in the oven is controlled by a thermostatic gas tap and is variable over
the range 130°C to 260°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 each shelf position is approximately equivalent to one gas mark.
Good use can be made of this temperature variation if several dishes requiring different
temperatures are to 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 – please see chart on next
page. It is not necessary to preheat the oven but advisable for a range of dishes. The oven
is capable of 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.

Do's and Don'ts
DO read the user instructions carefully before using appliance for the first time.
DO allow the oven 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 appliance.
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 or oven doors.
DO NOT use or store flammable materials near this appliance.

Leaks
If a smell of gas becomes apparent, the supply should be turned off at the cylinder
IMMEDIATELY. Extinguish naked lights including cigarettes and pipes. Do not operate
electrical switches. Open all doors and windows to disperse any gas escape.
Butane/Universal LPG is heavier than air; any escaping gas will therefore collect at a low
level. The strong unpleasant smell of gas will enable the general area of the leak to be
detected. Check that the gas is not escaping from an unlighted appliance. Never check for
leaks with a naked flame, leak investigation should be carried out using a leak detector
spray.
Abnormal Operation
Any of the following are considered to be abnormal operation and may require servicing.
•Yellow flames.
•Soot on cooking pans.
•Burners not igniting properly.
•Burners failing to remain alight
•Gas valves difficult to turn
