Cooking Guide
Your gas oven is a newly designed oven which incorporates an indirect burner located
under the oven base plate.
If you have previously been used to cooking with gas you may need to slightly alter your cooking methods.
The bottom of the oven is hot and is ideal for browning the underside of shallow pastry dishes and pizzas.
Other items should be cooked nearer the top of the oven.
When baking cakes, scones etc on more than one shelf the best results will be achieved by swapping the
shelf positions over half way through the cooking process.
Safety
NEVER allow fat to build on the oven base.
As with all ovens, clean and empty fat regularly from the trays and oven base to avoid the possibility of
fat fires.
The oven contains a cooling fan at the top of the appliance which forces cool air over the fascia panel when
the oven reaches a set temperature to prevent it from becoming too hot.
The fan will continue to operate after the oven has been switched off, until the appliance cools down.
However, the oven door can become hot - keep children away from this appliance.
NEVER place anything on the bottom of the oven.
Do not line the oven walls with aluminium foil.
Do not place baking trays or the drip tray on the base of the oven chamber.
