5. Before Use
Before using the appliance:
- Ensure that all packaging materials have been removed.
- Clean the appliance with warm water and household detergent and dry carefully with a soft cloth.
- Ensure that the gas supply is connected and turned on.
- Ensure that the appliance is connected to the 12V DC battery for the cooling fans and spark ignition.
- Ignite the burner and heat the grill for about 20 minutes to eliminate any residual factory lubricants that might impart unpleasant smells to the food being cooked. Smoke may occur during this procedure. Open any windows and turn on mechanical ventilators to help remove the smoke.
- Ignite the burner and heat the oven for about 30 minutes at 200°C to eliminate any residual factory lubricants that might impart unpleasant smells to cooked food. Smoke may occur during this procedure. Open any windows and turn on mechanical ventilators to help remove the smoke.
? Only use LPG (Liquefied Petroleum Gas). The appliance operates on propane or butane. Propane is preferred over butane, because butane provides poor performance at an ambient temperature below 10°C and cannot be used at an ambient temperature below 5°C.

8. Safe Cooking
⚠️ The pans and trays supplied with this appliance are the maximum sizes. Do not use larger pans and trays. They may restrict good circulation of heat, which may increase cooking times.
The oven shelf allows 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 it forward until it stops, raise at the front and remove.
To place a shelf in the oven, lower it at the front and slide it backward until it stops.
The appliance is fitted with a cooling system. The cooling fan 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 fan will automatically switch off a few minutes after the appliance has been switched off, when the appliance has cooled sufficiently.
When either the grill or oven is first lit or after switching off, the cooling fan may operate intermittently. This is normal.
⚠️ Do not leave the appliance unattended when in use.
⚠️ Do not use the appliance while the vehicle is moving.
Turn the control knob back to the 0 position after cooking.
Keep the appliance clean and prevent accumulation of grease and food scraps.
⚠️ Never cover slots or holes in the appliance and never cover a shelf with materials such as aluminium foil. That restricts the airflow and may cause carbon monoxide poisoning.
⚠️ The food shelves and trays in the appliance are hot during and after use. Allow all parts to cool before touching them, as this can cause serious injury. Always use oven gloves when removing the shelves and trays.
9. 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 for SOG700 / 750 & SOV700 and over the range 130°C to 220°C for SOG52 & SOV52.
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, as 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.
Table 1: Approximate temperature zones
| Gas mark | ? [Oven Burner] | ? [Grill Burner] | ? [Broiler/Grill Element] | Dish |
|---|---|---|---|---|
| 1/4 - 1/2 | 90°C | 110°C | 130°C | Meringues |
| 1 | 110°C | 130°C | 150°C | Stewed fruit |
| 2 | 120°C | 140°C | 160°C | Rich fruit cake, rice pudding |
| 3 | 130°C | 150°C | 170°C | Baked custard, shortbread fingers |
| 4 | 140°C | 160°C | 185°C | Victoria sponge |
| 5 | 155°C | 180°C | 200°C | Whisked sponges, ginger nuts |
| 6 | 170°C | 190°C | 220°C | Short crust pastry |
| 7 (SOG700/750 & SOV700 only) | 185°C | 210°C | 230°C | Bread, scones, flaky pastry |

| 9 (SOG700/750 & SOV700 only) | 215°C | 240°C | 260°C | Quick browning |
⚠️ 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.
10. Maintenance and Cleaning
Thetford recommends an annual inspection service by an approved service centre. Between annual servicing, clean the appliance regularly after use. Before any cleaning work is started, the appliance should have been left to cool and be disconnected from the gas and/or electrical supplies.
- Always remove any spills or contamination immediately after use with soap and hot water. Towel dry the surface with a soft cloth.
- Use a non-abrasive multi-purpose cream cleaner and a nylon scourer pad to clean more stubborn dirt or grease.
- Use a proprietary stainless steel cleaner or polish to remove superficial surface scratching.
⚠️ Do not use abrasive cleaners, metal scouring pads or hard brushes. They could damage the appliance.
⚠️ Do not leave wet cloths, cleaning pads, residues of food or cleaning products or other dirt to dry on the surface. It can cause pitting, marking or even rusting.
⚠️ Always clean in the direction of the brushed finish and not across the grain.
⚠️ Cleaning agents containing bleach should not be left in contact with stainless steel.
? Mineral content in water (such as iron or lime scale) can affect the appearance of the metal.
The control knob can be removed for cleaning. The knob is easy to replace.
11. Gas Leaks
As soon as you smell gas:
- ⚠️ Ensure that all burners are turned off.
- ⚠️ Extinguish all naked lights and do not smoke.
- ⚠️ Shut off the gas supply at the gas bottle immediately.
- ⚠️ Do not use electrical switches.
- ⚠️ Open all doors and windows.
⚠️ LPG is heavier than air. Escaping gas accumulates at lower levels. By following the strong, unpleasant smell of gas, you can determine where the leak is located. To investigate where it is exactly, use a special leak detection spray. Never use an open flame to find the leak!
12. Troubleshooting
| Problem | Possible cause | Solution |
|---|---|---|
| Burner does not burn or burns unevenly | Gas bottle is empty Gas tap is closed Burner is wet or clogged |
Change gas bottle Open tap Dry or clean burner |
| Spark ignition does not spark | 12V DC battery is discharged Connections are loose Ignition points are wet or dirty |
Charge battery Secure connections Dry or clean ignition points |
| Control knob does not function | Knob is mounted incorrectly | Install knob correctly |
? If you cannot solve a problem, contact the authorised local Service Centre or Thetford Customer Service in your country.
