7. Always make sure the control knob is in the off position when you have finished grilling.
8. The grill must only be used with the door fully open.

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 nontoxic smoke may occur when using for the first time, open any windows and turn on mechanical ventilators to help remove the smoke.
Although the grill heats 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.
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.

Pans or other utensils MUST NOT be placed on the door when in its open position.

Operation of the Door
This appliance is fitted with our unique slide under door. When the door is opened 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 it stops in the parked position below.
   

To close the door
Follow above sequence in reverse.

• The grill pan supplied is multi functional, for use in grill or oven.
• The handle design allows removal or insertion whilst pan is in use.
• Always remove the handle when the pan is in use.
• The grill MUST only be used with the door open.

Using the Oven

2. Open door, push in the control knob and turn anticlockwise to full rate (Gas Mark 9, 240°C) – see Fig. 4.
   Fig. 4 – Oven Operation, Control Positions
   
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 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.

• 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.

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 making contact with 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

• Ignition must be carried out with the door open.
• 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.

Before using your oven for the first time we recommend the following:- Clean all surfaces with hot soapy water. Light the oven and set control knob to Gas Mark 5 (200°C) and heat the oven for about 30 minutes to eliminate any residual factory lubricants that might impart unpleasant smells to cooked food. A non-toxic smoke may occur during this procedure, open any windows and turn on mechanical ventilators to help remove the smoke.

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.

Do's and Don'ts

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/Propane gas is heavier than air; any gas escaping will therefore collect at 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 unlit appliance. Never check for leaks with a naked flame; leak investigation should be carried out using a leak detector spray.

MAINTENANCE

We recommend an annual service by an authorised service agent to maintain efficient appliance performance. In between annual service the appliance needs little maintenance other than cleaning. 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.

Regulations and Standards
In your own interest of safety, it is law that all gas appliances are installed and serviced by an approved competent person, in accordance with the local and National/European standards in force Failure to install the appliance correctly could invalidate any warranty or liability claims and lead to prosecution. 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 with regard to 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. LP gas appliances must not be fitted below ground level. e.g. in a basement

Position
A cut-out should be prepared as shown in the enclosed diagrams – Figs. 1 & 2. The location of the cut-out MUST comply with the dimensions shown and include a gas dispersal hole venting to the outside. We recommend the dispersal hole is baffled and positioned as shown in the diagrams. 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.

Under no circumstances should the gas dispersal hole be obstructed.
The appliance should be fixed in place using the fixing screw positions located in each side of the Oven opening. Make sure the appliance is fully home in the cabinet/aperture before fixing in place.

INSTALLATION

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. Ensure all combustible materials such as curtains and shelves are well clear of the appliance.
If other appliance/s are located below the oven we recommend conducting a temperature verification test to confirm any rise in temperature of the cabinet materials are within allowable limits and meet requirements specified in EN30-1-1, EN1949, EN1645-1, EN1646-1, EN1647, and EN721.
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 65^oC 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.

Gas Connection
Prior to connection ensure the local conditions for gas type and gas pressure match the appliance specification. (Gas type and pressure for this appliance are printed on the data badge located on the base of appliance)
The Ø8mm gas inlet is located to the rear of the appliance. Prior to connection remove the plastic protection plug from the fitting. The appliance MUST be connected using metal pipe manufactured from either copper, seam welded steel, seamless steel or stainless steel, which complies with the requirements of EN1949. Rubber tubing MUST NOT be used.

Electrical Connection
Cooling System: - A constant 12V supply is necessary at all times to ensure the cooling system operates correctly.
Spark Ignition: - The spark ignition generator MUST only be connected to a suitable 12V DC supply. We recommend using sheathed spade connectors to connect the generator to the power supply.
Ensure all electrical cables and wires are routed well clear of any heat source, including this appliance. Excess cord must be routed away from the appliance and must not come into contact with the oven or grill body. Any plugs must be accessible after installation to aid servicing.
To ensure correct operation and prevent changes in air pressure affecting 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 MUST be fitted, this must not exceed Ø25mm
• Cupboards below appliance MUST not allow gas to enter the living area.

Construction materials: - All cooking appliances become hot during use. It is important that 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 (EN 30-1). If it is not possible to install the appliance as detailed within these instructions please refer to Thetford Ltd for guidance.
